Often referred to as substrate “porosity,” substrate surface water absorptivity refers to the ability of a flooring substrate surface to absorb liquid relatively quickly. The coalescence of an impermeable floorcovering material and a non-porous concrete surface not only reduces moisture from coming in, but also from escaping.
Today, there is a growing demand for large-format ceramic and natural stone tiles. This necessitates proper specification and execution of floor surface preparation, particularly in relation to floor flatness, which is critical to successful floorcovering installation.
Waterproofing below-grade portions of buildings is increasingly important to owners as technological advancements and limited city space have pushed basements deeper into the ground and further into water tables.
When materials like concrete are constrained to prevent volume changes, large internal forces and stresses develop. Therefore, it is important for architects and engineers to work together to avoid inappropriately constraining building materials.
Building owners, designers, and residents/tenants are increasingly using exposed polished concrete floors for a variety of interior spaces because of its pleasing aesthetics. A polished concrete topping slab can be used to also encase embedded hydronic heating systems.
