This type of coating uses one coat of primer and a couple of top coats applied with a roller, spray or trowel. Compared to cement waterproofing, it offers more flexibility. This is because it becomes a gummy coating on the wall when the liquid cures. PU (polyurethane) waterproofing systems are known for their exceptional flexibility, elongation properties and capacity to eliminate cracks.
They offer excellent resistance against water, chemicals and UV radiation. Polyurethane systems can be applied to a wide range of surfaces, such as concrete, metal and wood. They are commonly used for roofs, terraces, balconies, and wet areas such as bathrooms and kitchens. Weberdry PUR Basic, PUR seal, PUR seal aqua and PUR seal 2K are the ideal choice for polyurethane-based waterproofing.
Waterproof membranes with fewer seams will generally last longer because they have fewer weak spots. As a result, liquid membranes can be more durable than solid membranes, as long as equipment installs sufficient layers. Redundancy is another factor to consider. Materials such as thermoplastics come in individual layers, and that lack of redundancy can make them more susceptible to fail.
Before explaining what waterproofing materials are, it is necessary to explain the concept of waterproofing. Many of the product warranties used by waterproofing companies can be void if they are not installed by a certified professional waterproofing contractor. The cementitious method of waterproofing can be used to cover waterproof roofs, such as those of bridges, dams, wastewater treatment plants and tunnels. PU-B 2K polyurethane, a bitumen-based two-component liquid waterproofing material, which is included in the Baumerk product catalog, provides ideal living spaces by providing the most accurate waterproofing required on outdoor surfaces such as balconies, terraces and roofs.
Structural waterproofing systems of a mixture of hot melt liquid bituminous rubber with an interspersed reinforcement can be used in roofing and podium applications to provide a seamless waterproofing membrane for roofs and podiums with high vegetation and are sometimes specified for winter applications where low temperatures are common. The durability of the waterproofing coating depends on the type of polymer used by the manufacturer to manufacture the liquid waterproofing agent. Comprehensive waterproofing measures are often added to the building to control humidity during construction, and waterproofing materials are applied after the structure is built to eliminate any problems that may arise. Membrane waterproofing materials are one of the most preferred waterproofing materials in the construction industry.
Bitumen waterproofing systems use bitumen, a petroleum-based material, to create a reliable waterproofing membrane. Weber offers a wide range of chemicals and waterproofing products that have been specially designed to meet the diverse waterproofing requirements of different areas of a building, ensuring comprehensive protection.
