Bitumen Membrane:

Bitumen Membrane: The Integrated Engineering Solution for Protecting Structures Against Water Leakage

Moisture and water accumulation are among the most dangerous factors threatening the structural integrity of buildings. Over time, they lead to concrete deterioration and steel corrosion. At Taj Al Rahmah, we recognize that choosing the right waterproofing system is the most critical investment in a building’s lifespan. Therefore, in this article, we highlight Bitumen Membranes as one of the world's most trusted and approved waterproofing solutions.

What is a Bitumen Membrane?

Bitumen membranes are waterproofing shields made from Modified Bitumen. They are internally reinforced with layers of polyester or fiberglass to provide the necessary strength and flexibility. They usually come in rolls with a thickness typically ranging from 3 mm to 4 mm.

Why Do We Rely on Bitumen Membranes in Our Projects?

These membranes possess characteristics that make them the first choice for contractors and engineers, most notably:

  • Superior Water Resistance: Provides a completely impermeable protective layer against rainwater and groundwater.

  • High Flexibility: Thanks to additives like SBS or APP, the membranes withstand minor structural movements without cracking.

  • Long Lifespan: They resist soil chemical reactions and temperature fluctuations for many years.

  • Strong Adhesion: When installed correctly, they bond perfectly to the concrete surface, preventing water from seeping under the insulation layer.

Common Types of Bitumen Membranes

  • APP (Atactic Polypropylene): Modified with thermoplastic, making it ideal for high-temperature regions (such as the Gulf countries) due to its high UV resistance.

  • SBS (Styrene Butadiene Styrene): Modified with synthetic rubber, offering extreme flexibility, making it best for areas exposed to severe cold or constant thermal expansion and contraction.

Professional Waterproofing Stages at "Taj Al Rahmah"

To ensure maximum efficiency, we follow precise steps during execution:

  1. Surface Preparation: Thoroughly cleaning the surface and treating any cracks or honeycombing in the concrete.

  2. Priming: Applying a liquid bitumen primer to ensure strong adhesion of the membranes.

  3. Torch Welding: Using a blowtorch to heat the underside of the membrane and bond it accurately.

  4. Overlapping: Ensuring a proper overlap (approximately 10 cm) and carefully welding the joints to eliminate any gaps.

  5. Testing: Conducting a flood test to ensure the success of the waterproofing process before proceeding to the next steps.
