BITULINE Extra Waterproofing Membranes

BITULINE Extra Series

Foundations, basement retaining walls, and all below-ground structural elements are constantly exposed to increasing soil pressure, groundwater movement, and temperature fluctuations. In conditions where standard waterproofing membranes may not provide sufficient performance, the BITULINE Extra Series offers a more robust solution.

Manufactured with APP (Atactic Polypropylene) modified bitumen, the Extra Series features heavier reinforcement and enhanced tensile and crack resistance, providing durable, long-lasting waterproofing for demanding construction environments.

What Is BITULINE Extra?

BITULINE Extra is a premium APP-modified bituminous waterproofing membrane designed with increased reinforcement weight for superior mechanical performance.

Key features include:

  • Enhanced reinforcement for greater mechanical strength
  • APP-modified bitumen for reliable performance in both hot and cold climates
  • Heat-welded joints that ensure complete waterproof sealing
  • Consistent quality through advanced manufacturing processes

These characteristics make BITULINE Extra a dependable waterproofing solution for projects exposed to demanding environmental conditions.

Frequently Asked Questions

What is the difference between BITULINE Extra and BITULINE Prima?

The Extra Series features heavier reinforcement, providing greater mechanical strength and improved performance in harsher climate conditions compared to the Prima Series.

Where is BITULINE Extra recommended?

It is ideal for foundation waterproofing projects located in regions with significant temperature variations or demanding environmental conditions.

Can water penetrate through the membrane joints?

No. When installed using the recommended heat-welding method, the membrane forms fully sealed joints that provide complete waterproof protection.
