Additional Details
Zemdrainsup®/sup is a Controlled Permeabity Formner (CPF) made from fine polypropylene fies assembled in such a way as to create a sheet with a large number of fine pores of controlled size, with appropriate porosity and permeable to water and air. The two sides of the faic are different and have different functions: The draining side collects air and water and allows their evacuation at the interface with the shuttering. It is composed either by black coarse fies, embossed (Zemdrainsup®/sup 'Classic') or by a specially shaped plastic grid(Zemdrainsup®/sup MD). The filtering side retains the cement particles at the surface of the concrete so that a dense, strong cover Crete is obtained. It is composed of very fine fies bonded in a way that will not stick to the concrete. Fies are 'grey' for Zemdrainsup®/sup Classic, and 'white' for Zemdrainsup®/sup MD. No release agent shall be apped on Zemdrainsup®/sup. Zemdrainsup® /supproducts are covered by several DuPont patents. You will find the precise product specifications under the section Data sheet.r
