Marquee Flooring Solution

Marquee Flooring Solution

Have you ever walked into your company’s warehouse, manufacturing floor, or retail area to discover a large crack in your concrete floor that you're pretty sure wasn’t there the day before? Perhaps you’ve just had a brand-new concrete floor poured for your new facility, and a week later it’s covered in tiny cracks. Cracking is part of concrete’s natural tendency. When it’s first poured, concrete is a liquid. Over the course of a couple of days, it hardens into a solid, shrinking as it does so. This initial shrinking often results in hairline cracking within the first few days of installation. Different mixtures and ratios of the cement may minimize some cracking, but can’t eliminate it completely. The chemical and physical reactions within the concrete don’t fully stop after it initially settles. Occasional cracking due to shrinkage can continue for years—so the occasional crack isn’t anything out of the ordinary. This kind of cracking is natural and inevitable and generally does not compromise the strength of the floor. Concrete has very high compressive strength, but low tensile strength—that is, it stands up very well under heavy loads, but does not tolerate stretching or bending of any kind. If exposed to severe changes in temperature (as in a building without climate control) a concrete floor may crack as it expands. A sudden increase in your concrete cracking may result from unusual pressures beneath the foundation. For example, after a heavy rainstorm, some types of soil may swell with water and exert pressure upward against your concrete foundation, creating more tensile stress than it can handle.

In the same way, unstable soil can cause shifts beneath the slab (as is possible with a construction site that hasn’t been graded properly). Especially large and deep roots from nearby trees can also cause cracking, though this is more common in residential areas than industrial ones. Again, in most cases, hairline cracks are harmless and don’t compromise the strength of the floor. Deeper cracks can cause a few other problems, however. Since concrete is porous, some transfer of vapours from the ground into the building is inevitable (Marquee’s WFM has vapour-proof capabilities due to its gas/air sealing properties). Deep cracks, however, can create a larger channel for gases such as water vapour or radon to enter, creating potential problems for workers. Cracks can also become a place where moisture and spilled liquids can more easily seep in, causing staining or (if your facility deals with food or organic matter of any kind) can encourage the growth of bacteria within your floor. Cracks that physically disrupt the surface of the floor can also cause issues. Not only can they create a tripping hazard for employees or customers, the exposed edges become more susceptible to spalling, especially if there are forklifts or other vehicles running over it regularly. Cracks on the smooth surface of the floor become a gathering spot for dust and debris, making it harder to keep your floors sanitary.

Marquee™ Flooring Solution is a major advancement in flooring waterproof technology. A single coat of WFM™ will gives a hard, durable 0.5mm thick coating with excellent resistance to water and aggressive chemicals for the protection of concrete floors in the most demanding internal and external environments. 2-3 coats of WFM™ application for flooring system, at 0.5mm thickness per coat, are always recommended. Marquee™ has also developed her own spray-gun machine to enable the ease of application and to give a smooth surface finishing. It hydrates rapidly to form a dense, hard wearing, durable coating, which exhibits waterproofing and elasticity properties, ensuring no permeability to water, air or gases and long term performance without cracking.
