The controlled permeability formwork (CPF) liner Zemdrain® drains the water from the concrete surface, achieving a harder, denser and more resistant surface finish. This significantly increases the service life of the concrete structure.
As well as delivering increased surface hardness, Zemdrain® CPF liner produces a blowhole free, low-porosity concrete finish. The improved surface ensures lower growth of microorganisms and algae as well as better freeze-deicing salt resistance, and at the same time increases abrasion resistance.
