Bitumen-Rubber Based Waterproofing Materials: Flexible and Durable Solutions
Waterproofing is vital for the longevity and structural integrity of buildings. Especially in areas exposed to water, such as floors, foundations, terraces, and retaining walls , flexible waterproofing products with high crack-bridging capabilities should be preferred. In this regard, bitumen-rubber based waterproofing materials stand out with their superior adhesion and elastic structure. The combination of bitumen’s water impermeability and rubber’s flexibility provides effective protection in both reinforced concrete structures and detailing solutions.
What are bitumen-rubber based insulation products?
Bitumen-rubber based waterproofing materials are single-component or two-component products, usually applied cold, produced by mixing modified bitumen (asphalt) with synthetic rubber polymers. After application, they form an elastic waterproof layer, protecting the structure from the harmful effects of water.
Areas of Application
-
Foundation waterproofing and retaining wall waterproofing.
-
Terrace and balcony surfaces
-
Wet areas (bathroom, kitchen, toilet)
-
Underground parking lots and retaining wall applications.
-
Expansion and detail solutions
-
Joints between asphalt surfaces and concrete.
Advantages of Bitumen-Rubber Based Materials
✅ High Flexibility: Thanks to rubber additives, it has high crack bridging properties. It adapts to the structure’s operation.
✅ Cold Application: Generally does not require oven or heating. Easy to apply.
✅ High Adhesion: Excellent adhesion to many surfaces such as concrete, metal, brick, and PVC.
✅ Water and Moisture Impermeability: Provides complete protection against water and moisture thanks to its bitumen content.
✅ Chemical Resistance: Some formulations are resistant to salt water and mild chemical environments.
✅ Ease of Use: Can be applied with a roller, trowel, or brush. Dries quickly.
✅ UV Resistance (in select products): Some products are also resistant to direct sunlight.
Things to Consider Before and After the Procedure
-
The surface must be free of dust, dirt, oil, and loose particles.
-
If necessary, a primer should be applied to improve adhesion.
-
Application thickness should be adjusted according to manufacturer instructions, taking curing time into account.
-
A protective layer (geotextile, screed, ceramic, etc.) may need to be applied.
