Waterproofing sheet manufactured with a formulation based on linear polyethylene that provides high flexibility and welding properties, suitable for works that require a waterproofing barrier with greater stability than HDPE.

Smooth (ALVATECH 5002) or structured (ALVATECH FIX) waterproofing sheet made of high density polyethylene. The specific formulation improves the welding performance, emphasizing its mechanical properties and chemical resistance.

High density polyethylene profile is a joining element between the geomembrane and a concrete work, which ensures a complete sealing of the work.

This is a polyethylene sheet, also known as Thermofilm, use during the bioleaching process with sulphurous metal for non metallic mining.

The formulation gives an excellent chemical resistance, 70% of light transmission and high thermic effect.
