Mold on hardscaping can be avoided with simple techniques! Hardscaping can be relatively maintenance-free. However, issues may arise if your patio or pool deck is not properly maintained or the initial installation isn’t correct. The first topic in the “Battling Mother Nature” series addresses how to avoid having a persistent mold and/or algae issue on any type of hardscape installation. The problem is often thought to be not enough sunlight in that area (particularly in the case of mold and mildew). Of course, it may help to have plenty of sunlight to mitigate the mold growth on the hardscaping. However, the problem is not the surface. It lies underneath. The problem is almost always about the substrate in paver, tile and other types of exterior or interior environments. The unfortunate appearance of mold and/or algae can readily be avoided with proper installation vs the age-old excuse of insufficient sunlight or other natural causes. The Problem and Solutions So,[...]
Natural stone for residential or commercial vehicle specification One of our prospective clients asked us about the ability to use natural stone pavers ie: travertine, limestone, sandstone or marble for re-designing a commercial and pedestrian plaza area where commercial trucks and cars will be driving on the plaza. They also wanted to know if we could produce the pavers in 2 ¼” thickness, as well. The plaza carries both commercial vehicles and cars. Along the plaza are pedestrian walkways. Yes, we can produce pavers at 2 1/4″ thick as well as 3″ or any thickness desired. As far as the concern re: the ability to handle truck traffic, the larger issue is the surface dimension of the pavers (ie: not necessarily the thickness of the pavers) as a fulcrum point or large void underneath the center of any paver can easily result in failure. Consequently, a 4″x4″ paver would be highly unlikely to ever snap or fail, whereas, a large format paver[...]
Cell-Tek Stabilization Grids Yes, even for the backyard pool deck or patio. The need for stabilization grids is something that is largely unrecognized throughout the construction industry which sort of boggles the mind. I would say that the large-scale industrial masonry world is understood because they have heavy-duty architects working on road projects, etc. those that requires forethought, and longevity. Unfortunately, on the mid-size to small scale projects ie: parking lots to backyard patio or pool projects, it’s usually not a consideration for reasons that are not understood by me. Stabilization is at the heart of the project when it comes down to longevity of the installation. Anybody can lay down some stone or pavers on soil or grass or anything and they’ll stay there for a week, a month or a year, but if you want them to stay in place for 10, 20, 50 years, you need to[...]
Whenever rebar is used to reinforce concrete around a paving project (I emphasize a paving project because of the horizontal nature of the concrete usually means there will be water sitting on it for extended periods of time) the use of COATED rebar is imperative. The iron in the rebar will eventually oxidize (rust) and expand in the process. The more it oxidizes, the more it expands. The more it expands the more water it can collect and therefore the more it oxidizes and so on and so forth. Eventually you will get a massive failure like this municipal project on the Malaga (Spain) Beach Promenade.
By the way, no sense in using coated rebar if you don’t also coat the ends yourself after cutting the pieces to the necessary length for your install.
For those that may be interested contact me for information regarding a new generation of lightweight rebar that is a[...]
Remember, when implementing or installing a certain fixed pattern it is important to stick within the parameters of the original design. Improvisation and creativity are acceptable and even very admirable in the appropriate …..in this example; not so much!
