Polythene building film will provide a moisture and vapour barrier for use with slab on ground construction. The low density polythene film membrane is available in a range of thicknesses and roll sies, and can be used as a concrete underlay and as a curing blanket.
The concrete underlay membrane will prevent moisture from penetrating beneath the slab. This prevents damage to floor coverings from rising damp and mould.
It also gives a stronger and denser slab, prevents concrete wastage and slows the curing process. It resists attacks by acid or alkaline soils and does not deteriorate when it comes in contact with water. Polythene building film also facilitates and speeds the removal of formwork.
Used as a curing blanket, the film gives a stronger slab by preventing the escape of heat and moisture, thereby slowing the curing process.
