High-quality elastomeric waterproofing membrane whose bitumen mixture consists of refinery bitumen and elastomers (SBS). The membrane has as reinforcement non-woven polyester (P), or glass felt (V) and as top coating polyethylene film (F), aluminum foil (ALU), natural gray mineral mosaic (M) or colored mosaic (white, red, green ). Alternatively, quartz sand or talc can be used.

Asphalt can be made more elastic by adding polymers of the SBS type (styrene-butadiene-styrene)

APP Plastomer waterproofing membrane, we characterize the membrane, the bituminous mixture of which consists of refinery bitumen and thermoplastic polymers (IPP,APP). The membrane is reinforced with non-woven polyester. The upper surface of the membrane is protected by a mosaic, while the lower surface is covered by a polyethylene film suitable for use as a flamethrower.
Plastomer: Asphalt can be made more plastic by adding polymers such as APP (disordered polypropylene)

• Good resistance to low and high temperatures
• Completely waterproof
• Good resistance to acids and bases

• Good tensile strength and correspondingly high elongation
• Good resistance to nail tearing and static loading

• Excellent UV protection
• Increases membrane life
• Reduces the spread of flame in case of fire

The reasons for the evolution of sealing surfaces with two or a single layer of bituminous membrane have been analyzed, as well as the selection criteria for bituminous membranes in general. In fact, examining specialized examples over the last 35 years, we came to the conclusion that the two-layer waterproofing system with modified bitumen membranes and high-quality reinforcement is – from an economical and technical point of view – the most reliable and longest-lasting solution.
