Product description: Due to the poor quality of traditional concrete surfaces, visible damage to the concrete often occurs after just a few years. The use of Zemdrain® modifies the surface characteristics of the concrete which considerably improves all concrete properties increasing quality and durability. Zemfrasa is exactly the same as Zemdrain® MD just with the adding of a self-adhesive backing. Zemfrasa promotes the increase of density in surface concrete.
Zemdrain® controlled permeability formliners (CPF) considerably improve the quality of the concrete surfaces of vertical and inclined walls. The low water / cement ratio, virtually blowhole free concrete surface produced by Zemdrain® is uncontaminated by release agent residues. Thus, the concrete has an increased service life expectancy with reduced maintenance requirements.
