Contaminated concrete can be Controlled by injecting With Epoxy grout

Remediation of air pollution can be costly and theoretically difficult. Many condition and local pollution control agencies have discovered that encapsulating contaminated concrete is the most cost-effective and long lasting solution for existing contamination. 100% sound epoxy can seal pollutants into the concrete with levels of 10 to 100 mils dense. In effect, the encapsulation works like an insect trapped in amber. Solids, gasses, and fluids are all trapped inside a sound hard capsule. Contaminants are thus in a position to be left in place, with no risk to crews that might have had to work in close proximity to remove them.
It is a good idea to choose a white, yellowish, or red color for the first coat, or “seal layer.” Subsequent topcoats are a contrasting color like grey or brown. In this manner, workers active the contaminated floors are alerted when wear has made re-coating necessary. The contrasting colors thus give a “wear meter.”

100% epoxy has no odor, can continue as heavy as needed, and comes in colors as well as clear. When applying floor seals that can be 20 to 500 mils solid as they repair and level imperfect floor areas, it is advisable to consider the elevation of the layer as well as the length and width issues of normal roll-on applications. When drinking water is poured on a glass, it protrudes above the surface at the edges. Tugging a finger though the water, one views flattening at the access and exit factors due to its surface pressure. When leveling floor surfaces, these same ramifications of the epoxy’s surface anxiety must be dealt with. Quite simply “self-levelling,” which is imperfect even for fluids like water, won’t produce a toned top level of epoxy.

100% epoxy coatings do not shrink and can harden at any level it is remaining at after being catalyzed. But special procedures are needed in order to assure a set surface while filling up uneven anomalies in the substrate. Experience has motivated that using a squeegee-like movement with an extremely short nap roller (3/16″) creates a pool of epoxy that can be pulled towards you to drip into low areas while keeping the top flat. Care must be used to apply a straight coat at the surface, and too much moving can cause the top to try to contour along the floor’s imperfections.
