Bitumenemembraane

Bitumenemembraane, often referred to as asphalt membranes or built-up roofing (BUR) membranes, are a fundamental waterproofing material used extensively in construction. They are composed of asphalt (bitumen) that has been modified or blended with other materials to enhance its properties. The asphalt is typically applied in layers, often in conjunction with reinforcing fabrics like polyester or fiberglass, to create a durable and continuous waterproof barrier.

The primary function of bitumenemembraane is to prevent the ingress of water. This makes them ideal for a variety of applications, including flat or low-sloped roofs, foundations, tunnels, bridges, and retaining walls. The multiple layers of bitumen and reinforcement provide excellent resistance to hydrostatic pressure and environmental degradation.

Installation usually involves heating the bitumen to a molten state and applying it with mops or specialized equipment. The reinforcing fabric is embedded into the hot bitumen, and subsequent layers are added to achieve the desired thickness and performance. The top layer may be coated with granules or a reflective coating to protect the bitumen from UV radiation and reduce heat absorption.

Bitumenemembraane are known for their longevity, cost-effectiveness, and proven track record in waterproofing. While they require careful installation to ensure a seamless and effective barrier, they remain a widely trusted and reliable solution for many construction waterproofing needs. Their adaptability to various shapes and substrates further contributes to their enduring popularity in the building industry.
