Oct 01, 2020· Cellular concrete is a mixture of cement, water, and preformed . The purpose of the is to supply a mechanism by which a relatively high proportion of stable air voids can be induced into the mixture and produce a cellular or porous solid upon curing of the mixture. When cellular concrete hardens, it has an oven-dry density of 50 lb/ft3 (.8 t/m3)or less.

How it works. Our polyurethane method uses the concrete slab itself as a means of delivering poly s that raise concrete, fill voids, and stabilize soils. A ⅝" hole is drilled through the slab into the subgrade. A tapered delivery port is installed into the ⅝" hole. The injection gun is connected to the port.
