Alvatech FIX (HDPE – LLDPE)

A waterproofing membrane made of high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE). The surface is textured on one or both sides, with a large number of spikes (57,000 spikes/m2) over 0.9 mm in height, which makes the membrane extremely stable when waterproofing steep slopes (high coefficient of friction and angle of friction).

We are the only company that offers a textured geomembrane with a width of 7.5 metres, which optimises installation costs as it reduces the number of welding seams required.

It is mainly used in structures that have very steep embankments (recommended for slopes of approximately 20% -12º or more).
