Alvatech 5002 (HDPE)

A smooth waterproofing membrane made of high-density polyethylene.

The specific formulation of this product gives it excellent weldability, enhancing its mechanical properties and chemical resistance. It is manufactured by a flat die extrusion process (calendering system) using the latest technology, which ensures excellent thickness control and a uniform surface finish (with a slight relief to make the product easier to install on the structure).

The 7.5 m width optimises installation costs and quality control on site, and significantly reduces the number of welding seams required to attach the membrane to the structure, when compared with a narrower sheet.
