Controlled permeability formwork (CPF) liner with a self-adhesive backing.
Controlled permeability formwork (CPF) liner that considerably improves the quality of the concrete surfaces of vertical and inclined walls. It is fixed to formwork before erection and once erected, concrete is placed and compacted in accordance with normal practice.
The liner retains the concrete fines whilst allowing the controlled drainage of excess air and water that is normally trapped at the concrete/ formwork interface. Additionally, water retained within the formwork side of the form liner is given back to the concrete during the curing phase.
Use of the liner optimizes the surface water/ cement ratio, minimizes blowholes and improves early age curing to give a high quality durable concrete surface with optimum resistance to all forms of environmental attack.
Flat, convex, concave, timber, steel and plastic.
