Bituminous membranes are multi-layer membrane made by distilated and modified bitumen, additivated by synthetic polymers APP or SBS elastomers, reinforced with woven/non woven polyester or glassfiber mat for elasticity and durability.

This hydroisolation solution is a result of long experience in waterproofing research and high technology.

APP membranes can be applied until -10 Celsius degrees and SBS until -25 Celsius degrees.

The upper face of the membrane consist of slate grains of different collors or aluminium layer, which reduces heat intensity and deterioration because of UV rays.

Bituminous membranes can be applied on:

- terrases, roofs, open roof buildings, using polyester reinforced membranes covered with slate grains.

- tunels, underground works, bidges, garden terrase, using stronger polyester reinforced membranes or counter roots membranes.

- on materials that can dammage on fire, as polystyrene, wood. In this case it will be used auto-adhezive membranes as intermediate layer.
