Project Size – 250,000 SF.
Problem – New construction with high levels of moisture in concrete. High Moisture levels in new concrete can cause issues for carpet, tile and coatings
Solution – Areas with high moisture content were shotblasted to prep flooring followed by application of Mapei Planiseal VS to cap the moisure. Mapei Novoplan 1 self leveling cementitious product was then applied to level surface. High areas were mechically removed with scarifiers. 60,000 SF of deep areas were filled with Ardex K500 and polystyrene beads providing a lightweight filler solving elevation issues in the surface.
About Products – Moisture Mitigation System
Shotblasting – If not familiar with shotblasting, this is a surface prep machine that shoots tiny ball bearing at the concrete at high velocity. The process removes the top layer of the cement removing bond (adhesion) breakers while opening the pores. It also increases the surface area increasing adhesion of the epoxy moisture cap (Mapei Planiseal VS)
Mapei Planiseal VS – This is a two part, low viscosity epoxy with 100% solids that soaks into and adheres to shotblasted concrete. It is a highly effective commercial product for capping moisture in new concrete slabs. Because it is a low viscosity epoxy it penetrates deep into the floor creating an iron bond. It is a low odor, VOC compliant and a single coat application. Planiseal PDF
