Introduction to prefabricated waterproofing

Prefabricated waterproofing is a material designed to protect structures against the penetration of water and humidity. It comes in the form of sheets or rolls that are already prepared at the factory, making it easy to apply on different surfaces. These membranes are widely used in construction to guarantee the durability and resistance of roofs, terraces, walls and other elements exposed to the elements.

Its manufacturing includes waterproof materials and compounds that provide high mechanical, chemical and thermal resistance. The use of prefabricated waterproofing represents an efficient and reliable solution to prevent leaks, helping to maintain the structural integrity and improve the interior comfort of buildings.

Chemical composition and base materials

Prefabricated waterproofing materials are commonly composed of asphalt modified with polymers, such as SBS (Styrene-Butadiene-Styrene) or APP (Atactic Polypropylene), which improve the flexibility and resistance to aging of the product. In addition, fiberglass, polyester or non-woven fabric reinforcements are incorporated to increase mechanical resistance and prevent the formation of cracks.

These base materials ensure that the membrane maintains its integrity in the face of thermal changes, structural movements and chemical exposures. The combination of these components allows the prefabricated waterproofing to have excellent elasticity, adhesion and durability properties.

Physical and mechanical properties

Among the most important physical properties are tensile strength, elongation, punching and tear resistance. These characteristics guarantee that the membrane withstands mechanical stress derived from installation, settlement or structural movements without compromising its waterproof function.
