Sustainable Natural Stone: A Timeless Choice for Eco-Friendly Design

In the age of sustainability, the materials we choose for construction and design play a pivotal role in shaping a greener future. Among these, natural stone is sustainable and stands out for its timeless beauty, durability, and its remarkable eco-friendly characteristics. Architects, landscape designers, and builders seek to reduce the environmental impact of their projects. Natural stone offers an eco-friendly option that aligns with aesthetic and ecological goals.

The Enduring Appeal of Natural Stone

Natural stone has been used in construction for millennia, from the ancient pyramids of Egypt to the Parthenon in Greece. Its enduring appeal lies in its organic beauty, variety, and versatility. Whether it’s granite, limestone, travertine, marble, or slate, each type of stone brings a unique texture, color, and character to a project. This aesthetic richness is complemented by the stone’s inherent strength and longevity. Structures and landscapes remain resilient and visually appealing for generations.

Sourcing and Extraction: Minimizing Environmental Impact

One of the key factors in natural stone’s sustainability is responsible sourcing. Unlike synthetic materials, natural stone requires no chemical processing or harmful manufacturing processes. However, the environmental impact of stone extraction can vary significantly based on practices employed at the quarry.

Sustainable stone quarries focus on minimizing the ecological footprint by:

– Rehabilitating Quarry Sites: After extraction, quarries can be restored to their natural state or repurposed for new uses, such as nature reserves or recreational areas.

– Efficient Use of Resources: Advanced techniques in quarrying reduce waste and optimize the use of natural stone, ensuring that the maximum amount of material is extracted with minimal disruption to the surrounding environment.

Energy Efficiency and Carbon Footprint

Natural stone is also lauded for its low embodied energy, which refers to the total energy required to extract, process, and transport the material. Compared to materials like concrete, brick, or synthetic composites, natural stone has a relatively low carbon footprint. Additionally, its thermal mass properties make it an excellent choice for energy-efficient buildings. Stone’s ability to absorb, store, and release heat can help regulate indoor temperatures, reducing the need for artificial heating and cooling.

Durability and Longevity: Reducing Waste

A significant advantage of natural stone is its durability. Structures built with natural stone often outlast those made with other materials, reducing the need for repairs, replacements, and the associated waste. In landscape architecture, stone features like walls, pathways, driveways, and patios can withstand the elements for decades without losing their integrity or aesthetic appeal. This longevity contributes to the material’s sustainability by minimizing the need for additional resources over time.

Recyclability and Reuse

Another sustainability benefit of natural stone is its recyclability. Unlike many synthetic materials with minimal processing, natural stone can be reused or repurposed. For instance, stone from demolished buildings can be reclaimed and used in new construction, preserving its embodied energy, and reducing the demand for new materials. Additionally, stone’s natural beauty often improves with age, making reclaimed stone a desirable choice for new and restoration projects.

Health and Environmental Benefits

Natural stone is a non-toxic, hypoallergenic material that doesn’t release harmful chemicals or volatile organic compounds (VOCs) into the environment. This makes it a healthy choice for indoor spaces, contributing to better air quality and a more comfortable living environment. Moreover, stone’s natural ability to withstand mold and pests reduces the need for chemical treatments, further enhancing its environmental credentials.

A Timeless Choice for a Sustainable Future

In conclusion, natural stone is not only a material of timeless beauty but also a sustainable choice for modern design and construction. Its minimal environmental impact, combined with its durability, energy efficiency, and recyclability, makes it an ideal material for projects that prioritize sustainability. As we look toward a future where the built environment harmonizes with the natural world, natural stone will continue to play a crucial role in creating spaces that are both enduring and eco-friendly.

By embracing natural stone, architects, landscape designers, and builders can contribute to a more sustainable future, where beauty, function, and environmental stewardship coexist in perfect balance.

Cleaning & Sealing Natural Stone – Limestone, Travertine, Marble

Cleaning and sealing a natural stone (limestone, travertine, or marble) pool deck or patio is less maintenance than its wood counterpart.  Stone sealer and cleaner products are very high-tech and require minimal maintenance to keep your natural stone looking like new over the years.

Cleaning natural stone on a regular basis:

  • Use any non-caustic degreasing agent (mild dish or hand soap) mixed in warm water. Agitate/scrub with a broom.
  • Use Stain Proof Alkaline Cleaner, formerly Oxy-Klenza™, https://www.drytreat.com/cleaners/regular/hanafinn-oxy-klenza.html
  • Power washing with residential strength power washers (i.e. 3000 PSI or less) is recommended. 

Minor restoration cleaning (mild surface etch):

This treatment will renew the original look of the stone surface and make the color ‘pop’ and is only recommended occasionally (maybe once every several years). Not in lieu of regular cleaning.

  • Dilute muriatic acid 10 parts water to 1 part store-bought muriatic acid.
  • Hose down the entire stone surface.
  • Pour diluted mix and move it around with a broom or rag mop – consider doing it in 10-15 square foot overlapping sections.  Don’t let it sit in one place without moving and agitating it.  The acid will neutralize after 10-15 seconds. Be sure to follow all safety procedures (eye protection, rubber gloves, etc.) as with any caustic material. However, this weak solution of diluted muriatic acid will not attack the skin under normal circumstances.  Additionally, after 10-15 seconds of contact with the stone, the acid will be neutralized (100%, more or less) and not harmful to plants, shrubbery, pets, etc.  
  • Finish by rinsing the surface with clean water.

Sealing natural stone when dry-set installation:

For a dry-set installation, it is not necessary to seal the stone.  However, sealing the stone with a high-quality penetrating sealer does provide some attractive benefits.

  • If you choose to seal the stone (to prevent staining that can naturally occur with any masonry product) we recommend ICP brand products, ‘Stain Proof’ sealer, and cleaner products.  Please be sure to follow all recommendations stipulated on this page for optimal results: https://www.drytreat.com/sealers/residential/stain-proof.html.  
  • Another benefit is the additional ‘locking in’ effect that the sealer has on prolonging the natural coloration of the stone. Over many years, the stone can fade slightly due to acid rain and other environmental factors. 
  • NOTE: Do not use concrete paver sealers – they are formulated as topical sealers. They can be very slippery and appear as an undesirable shiny coating on the surface.  Furthermore, the topical coating traps moisture. It doesn’t allow the stone to “breathe” (which is important for all natural stone products). 
  • NOTE 2: If you choose to purchase sealers from a “big box” retailer, be aware that (even within the same brand name) you will get a lesser quality product. The “big box” retailers force the manufacturers to make less expensive (lower quality) versions for them under the same brand labels. 

Sealing natural stone when wet-set installation:

  • It is best to seal the stone BEFORE grouting as the sealer also acts as a “grout release” and will make the grouting process faster and easier.
  • Please be sure to follow all recommendations stipulated by the sealer manufacturer. If using Stain Proof, please follow the recommendations on this page for optimal results: https://www.drytreat.com/sealers/residential/stain-proof.html.  
  • NOTE: you mustn’t use concrete paver sealers! They are formulated as topical sealers. It can be very slippery and appear as an undesirable shiny coating on the surface.  Furthermore, the topical coating traps moisture. It doesn’t allow the stone to “breathe” (which is important for all natural stone products). 
  • NOTE 2: If you choose to purchase sealers from a “big box” retailer, please be aware that (even within the same brand name) you will get a lesser quality product, as the “big box” retailers force the manufacturers to make less expensive (lower quality) versions for them under the same brand labels.

Driveway Installation Best Products (and Technologies) for Lifetime Value

Natural stone paver driveways are a thing of beauty, a real estate highlight, and a feat of engineering. They increase property values, up the curb appeal, and boost resale prices. So, what’s the best way to protect that investment and maintain its physical appeal? Let’s start at the basics, which means ensuring the natural stone driveway installation is done correctly.

There are two options for natural stone paver driveway installation.

  1. ‘Dry set’
  2. ‘Wet set’

And, at Gothicstone, we suggest all ‘dry set’ and ‘wet set’ installations include a cellular confinement system (CCS) underneath for maximum longevity and lifetime value.

Insider notes: ‘wet set’ driveway installation with natural stone pavers

An issue with ‘wet set’ (poured concrete slab substrate) particularly in climates that have a lot of freeze-thaw cycling, is that concrete slabs are used as the sub-base/substrate and often will crack. It’s often not a question of “if” the underlying concrete slab will crack, it’s “when” it will crack. And a cracked concrete slab will commonly transfer the crack(s) to the adhered surface stone or any material on top, such as concrete pavers, for that matter. The reality is very few contractors are willing to put the effort into making a slab that won’t crack because it takes extra work and expense. Utilizing rebar, a geo cellular confinement system, and a ‘separation membrane’ (such as Schluter®-DITRA & DITRA-XL) will mitigate the possibility of failure, as described below.

Geo Cellular Confinement System (CCS) to the rescue: Why implement in a ‘wet set’ driveway application?

Some people think the cellular confinement system isn’t needed under a large concrete slab. But we disagree. The fact is the minimal extra expense will all but guarantee that you will never have slab cracking. Water is going to get underneath the concrete slab and during freezing, it will expand. The cellular confinement system holds everything in place minimizing movement resulting from freezing and thawing environments.

Steps to installing a ‘wet set’ long-lasting driveway with a cellular confinement system:

To recap, if you want your installation to last a long time, follow these 9 steps:   

  1. Excavation with appropriate drainage considerations to mitigate water pooling underneath.
  2. Installation of geotextile to prevent gravel from sinking into the soil below it.
  3. Installation of the cellular confinement system following manufacturer’s best practices. 
  4. Fill the confinement system utilizing only clean (washed and graded) gravel. We strongly advise against using ‘modified/unwashed’ gravel mix.
  5. Installation of a top layer of geotextile on top of the gravel.
  6. Installation of rebar grid on the top of the gravel (preferably epoxy coated or ‘high-tech steel alternative’ composite rebar to avoid the risk of rust-causing future failure).
  7. Pour a fiber-reinforced concrete slab. It is imperative to follow the local code regarding the implementation of expansion joints.
  8. To ensure longevity, an extra step we recommend is to install a separation membrane such as Schluter®-DITRA & DITRA-XL on top of the concrete slab to mitigate cracks transferring through to the surface stone.
  9. Professionally install the appropriate natural stone including grout lines (and expansion joints where necessary) to enable expansion and contraction. This is imperative in extreme weather conditions. In a perfect world, ½” thin natural stone can be used when all the above steps are adhered to with precision. Otherwise, we would recommend the 1 ¼” standard thickness for exterior applications.   

In conclusion, there are redundancies in the above best practices instructions. There is almost zero chance of failure if all these steps are completed, and the resulting driveway should last a lifetime. 

Insider notes: ‘dry set’ driveway installation with natural stone pavers 

‘Dry set’ installation is the ideal method for driveway stone pavers. It avoids excessive movement of the stone due to heaving in colder climates. Also, stress from an expansion of the stone in hot climates. These unwanted issues are inherent in poured concrete slab systems. ‘Dry set’ installation is an environmentally sustainable alternative that allows water to pass through it rather than create problematic water runoff.

For the safest approach, it’s best to select natural stone pavers of smaller sizes. When working with smaller pieces, such as 4”x4”, 4”x6”, or even 6”x6” cobblestones, use a ‘dry set’ application.  But if your customer wants something different than the classic cobblestone 4”x4” granite, limestone, or porphyry block, the key is to consider the flexural stress on the stone. If the stone surface is longer than 6 inches in any one direction, then a strong (high ‘flexural strength’) material is optimal, particularly when considering a ‘dry set’ application. Avoid natural stones prone to having natural fissures or clefting. 

Large format natural stone pavers in a driveway installation

Large format pavers can be successfully installed if the installation is done properly. You can install 12”x12”x1¼”, 16”x16”x1¼”, 8”x16”x1¼” or larger if it is installed correctly. But that’s a BIG “if”. Many contractors/masons rely too heavily on laborers to do the installations, emphasizing speed over quality. This isn’t a good idea. A small void or a “pea under the mattress” can cause failure.

Geo Cellular Confinement System (CCS) to the rescue

To mitigate shifting and cracking, install a cellular confinement system. Gothicstone recommends a cellular confinement system (CCS) under any base.  With driveways, it’s almost imperative due to tire track “rutting” to use a CCS.  For example, if you have a sand or dirt driveway, ruts inevitably occur over time.  But it also happens with blacktop driveways or any driveway where you have constant stress and load on two narrow tire tracks. The vehicle load will compress the ‘track’ area, whereas a CCS can keep the substrate from spreading out. This method prevents stress on the tracks from making ruts in your installation, and thus pieces from failing. Because when the ruts happen, there’s uneven compression on the pieces.  It’s the unevenness of the load where problems like this occur.   

Small 4”x4”x4” cubes/pavers typically won’t break, which is why people typically use this size of material, but they will be susceptible to rutting and shifting.  Often people want to use a larger format driveway stone. If so, a ‘dry set’ and a cellular confinement system are the approaches to use.

Ruts and cracks can be avoided

The larger pieces will help in that they won’t rut as readily, however, they may crack.  Whereas small driveway stone pieces will allow the material to “sink down” into the ruts without breaking. But they’ll allow the ruts to occur more easily.  Plus, more water is washing in between the joint areas because you have more joint areas. 

If you have a 4”x4” compared to a 16”x16”, you’re going to have about 1000% more joint area with a 4”x4” installation.  That’s an incredibly exponential amount of joint area because in a 16”x16” area, you will have 16 pieces of 4”x4” material (4 in one direction and 4 in the other direction) and then all those joint lines in between where the water will be entering and then allowing for either washout or heaving underneath it. 

So, the smaller driveway stone pavers do allow for more movement to happen but, eventually, they may cause ruts unless you use a cellular confinement system to keep everything underneath in place.

Keep in mind that vehicular weight will be on the pathway of the vehicle tires; that is where the bulk of the load or stress will go. 

Steps to installing a ‘dry set’ long-lasting driveway with a cellular confinement system:

To recap, if you want your installation to last a long time, follow these 8 steps:   

  1. Excavation with appropriate drainage considerations to mitigate water pooling underneath.
  2. Installation of geotextile to prevent gravel from sinking into the soil below it.
  3. Installation of the cellular confinement system following manufacturer’s best practices. 
  4. Fill the confinement system utilizing only clean (washed and graded) gravel. We strongly advise against using ‘modified/unwashed’ gravel mix.
    1. Follow local code requirements regarding the height/quantity of crushed stone/gravel required in your geographic area. 
    2. It’s considered best practice to compact every two inches of height when applying the gravel. 
  5. Installation of a top layer of geotextile on top of the gravel.
  6. Installation and compaction of screenings/’fines’ (concrete dust, sand, or small/fine gravel)
  7. Professionally install and compact the appropriate natural stone pavers.  Where small grout lines are open between the pavers, sand or polymeric sand can be swept between the joints. 
  8. To retain the beauty of the stone, you should use an impregnating stone sealer using a color enhancing impregnating stone sealer, so it keeps the stone looking new.  If you want the stone to age naturally, you don’t have to use any stone sealer at all. In any case, sealing in a ‘dry set’ application is not necessary.  Never use a ‘topical’ stone sealer (non-impregnating).

5 design approaches using natural stone pavers:

  • Creating a “deco” look. Use smaller pieces that can manage the load in the heavy traffic areas and install the larger stone along the sides.  
  • Placing smaller format material at apron entrances of driveways. The entrance apron, where vehicles turn in off the main road, typically takes an enormous impact as they swing into the driveway. In most of the United States, when you approach a driveway, there will be a bit of a bump or a swale causing impact. So, on the apron entrance, from the road to the driveway, consider using a smaller format stone. The smaller format driveway stone mitigates the impact of flexural stress, while at the same time smoothing the sloping transition to the street. 
  • Mixing and matching alternating sizes to provide attractive applications. Smaller driveway stone pieces on the apron can be cut from the same blocks of stone as the rest of the project applications. Whether it’s a long driveway, walkway, or pathway leading up to a patio or pool, for example, the entire project stone can match no matter the size or thickness of the material.
  • Picking the appropriate material if you select larger format driveway stone pieces. Gothicstone™ SEAHAZEtm limestone is extremely strong, has high compressive strength, and high flexural strength.
  • Choosing 4”x4”x4” cubes is not necessary.  It’s not necessary to go that thick, however, with carbon footprint, shipping costs, and other green initiatives being an increasingly important consideration, a 4”-thick paver is going to double the shipping cost of a 2”- thick paver. From both a cost-effective value engineering perspective and a carbon footprint perspective, a 2”-thick piece gives you a better value and is good for the earth!

Stabilization grids for large & small paver projects

Yes, even for residential pool decks or patio pavers!

Largely unrecognized throughout the construction industry in paver installation is the need for stabilization grids.  These grids are also called cellular confinement systems (CCS), load support grids, or geocells.  I would say that the large-scale industrial masonry world understands because they have heavy-duty architects working on road projects, those that require forethought, and longevity. On small to mid-size projects ie:  parking lots to driveways, backyard patios, or pool deck paver projects, it typically is not a consideration to use stabilization grids. 

Stabilization equals Longevity of Paver Installations

Stabilization is at the heart of the project when it comes down to the longevity of the installation. Anybody can lay down some stone or pavers on soil or grass and they’ll stay there for a week, a month, or a year. If you want pavers to stay in place for 10, 20, or 50 years, you need to have a stable substrate.  As with interior tile projects and exterior paver projects, it’s all about the substrate. Without the proper substrate, nothing else matters because you will have failure – 100% guaranteed.

Courtesy CellTek

So, without the soil stabilization under a paver installation, you’re extremely likely, in almost every scenario, to have some movement. There are some very stable environmental situations that may not necessitate it. Climates that don’t have much temperature change, climates that don’t have a lot of rain, and have very compact sandy soil, are where you will not get a lot of movement underneath. As you know, that is a small portion of the world we live in that has that kind of climate.

So, conversely, if you have a lot of rain, if you have a lot of temperature change, particularly if you have a lot of cycling in freeze/thaw, and that’s the real killer, you’re going to have movement in your substrate.  When you have movement in your substrate, you are going to have movement above your substrate because the substrate is what is holding your stone or pavers. For that reason, stabilization grids are recommended.

Paver Installation on Concrete Slab with Stabilization Grids

When you have a concrete slab, it’s the adage, it’s not IF your slab will crack or fail, it’s WHEN. Concrete slabs are extremely prone to failure because they are asked to perform very unforgiving and next-to-impossible tasks…to endure movement underneath them without cracking or failing. And, again, when you have movement underneath, you’re going to have the material on top crack and fail.  Even the concrete itself is prone to failure without movement from underneath because of heat, especially in hot climates, and or cold or thermally cycling climates, where it gets cold then hot, cold then hot. The slabs will expand and contract according to the heat and cold they are exposed to and particularly, the cycling of heat & cold, heat & cold. 

Small concrete slabs, for sidewalk sections 3’x3’ or 4’x4’ are not a big concern.  Unfortunately, enough people do not put on expansion joints, they use control joints, which when it fails, fail along the control joint. A control joint is nothing more than a little line cut into the surface of the concrete making it a little bit weaker on that line so if it cracks, the crack goes along that line that was cut into it. So, it’s a prettier failure.  The concrete slab is not the best solution. 

If there are no elevation problems or choose to raise your elevation, it’s perfect to put a grid down on top of the existing concrete slab and put pavers on top of that. 

Benefits of using STABILIZATION GRIDS

When there is failure such as washing out from too much rain underneath, and without a properly compacted substrate, you can have the substrate washing out. This happens from normal flooding, heavy floods, and the constant flow of water eventually eroding the substrate and gravel. A stabilization grid (or cellular confinement system) will hold the substrate in place so that it’s not possible to wash out.  The gravel can’t travel through the walls of the grid, so it holds it all together and in place. 

Use stabilization grids to combat the freeze-thaw danger

One of the bigger dangers is the freeze/thaw expansion and contraction issue that is extremely common in the climates of the upper forty-eight states in America and around the world. When you have snow and wintry weather, warm weather, then freezing weather, warm weather, and moisture-cycling, the moisture gets underneath the pavers and freezes. And, as we all know, when you look at ice cubes in your freezer, they all have a hump in them because when water freezes, it expands. So, you’re going to get the substrate holding water. If there is quick freezing overnight, the water will expand and therefore, your whole installation will heave up a little bit. 

When it heaves down, when you use the grids, the grids will hold it in place instead of it shifting a little bit every time. When it shifts a little bit every time, from heaving then relaxing,  heaving then relaxing,  heaving then relaxing, you can imagine things will start to spread out over many cycles and next thing you know your pavers are 1/8” apart then ¼” apart, next thing you know, they have those openings and more water attacking it and now you have bigger gaps for the water to go in and turn to ice and more washout issues, etc. The whole thing kind of goes to hell without the use of a stabilization grid or cellular confinement system.

Stone Cleaning and Sealing Tips for Natural Stone Pavers, Tile, Coping, and Step Treads. 

Hardwood decks/patios, as well as wood on houses/buildings, need to be power washed, cleaned, and sealed on a regular basis.   Although you power wash and seal a hardwood deck every year, natural stone deck maintenance is much less frequent.  Stone sealer and cleaner products are very high-tech and require minimal maintenance.

Stone Cleaner Maintenance for Natural Stone Pavers, Tile, Coping or Treads:

  1. Regular, basic maintenance type cleaning: *
    • Use a stone cleaner that is easy to find at any hardware store or
    • Use any non-caustic degreasing agent (mild dish or hand soap) mixed in warm water.
  2. Deep cleaning, minor restoration (mild etch) type cleaning:
    • Dilute muriatic acid in ten-part water to 1-part store-bought muriatic acid.
    • Wet the entire stone surface.
    • Pour dilute mix and move it around with a sponge mop – consider doing it in twenty square feet overlapping sections.  Don’t let it sit in one place without moving and agitating it.  The acid will neutralize after 10-15 seconds.
    • Finish by rinsing the surface with clean water.

Note: The acid should not be strong enough to do any damage to the ecology or be harmful to your flower beds next to the stone patio. Once the acid contacts the stone, there is a little bit of sizzle, a bit of chemical reaction that happens and then it should be neutralized.

Stone Sealer Maintenance for Natural Stone Pavers, Tile, Coping or Treads: **

With natural stone, you should never use a prophylactic coating type of sealer because the stone wants to breathe.  Using a “breathable” stone sealer tends to last many years longer.  When using a high-quality sealer, you will only have to seal every 5-15 years or longer.  Some companies offer both a color-enhancing stone sealer and a “matte” finish stone sealer. Both types of sealers are impregnating sealers and penetrate the stone about a ¼”.  The color-enhancing stone sealer will help the stone “pop” its deep rich darker color (like when it is wet but doesn’t add shine or sheen to the stone). The “matte” finish stone sealer leaves the stone the same color when it is dry. Gothicstone recommends Stain Proof, stone cleaner, and stone sealer products.   

Considerations when applying stone sealer:

  1. If grout was newly applied to the tile, pavers, coping, or treads, you should wait at least 2 weeks for the outgassing to complete before using a stone sealer.
  2. If only stone cleaning was done, seal after the stone is thoroughly dry, typically a day or two. 
  3. Follow the directions on the bottle for the impregnating sealer.

** We highly recommend purchasing sealer products from a tile showroom.  We recommend Stain Proof by Dry-Treat.
