Max Frank Zemdrain CPF Liner, 50m Roll
During compaction, the oiled impermeable/low-absorbent faced formwork traps air and excess water at the formwork interface. This results in an increased surface ratio with increased porosity and permeability. The resulting reduced density and blowholes produce a more open concrete structure.
The solution: Zemdrain® CPF liners drain excess air and water from the surface of the concrete. This reduces the water to concrete ratio in the outer 20 mm of the surface to nearly optimum values, and virtually eliminates blowholes. The resulting concrete has increased resistance to all aggressive elements.
Zemdrain non-woven liner lends concrete the following properties:
