Enhanced durability with Controlled Permeability Formwork Liner (CPF).
Zemdrain® improves the concrete’s ability to resist chemical attack by reducing the water-cement ratio and surface porosity, which limits the depth of chloride ion penetration into the cover zone and prevents induced corrosion. The result – an extremely durable concrete surface that is resistant to all forms of physical and chemical attack, as well as minimising biological growth and graffiti staining.
For a quality concrete surface to complement the use of Zemdrain® CPF liner, we recommend the use of MAX FRANK’s extruded fibre concrete spacers. Our fibre concrete spacers are produced from high-strength material to provide the most cost-effective, high performance spacers available on the market.
