Strong and Reliable Waterproofing
Bituminous membrane is a safe and comfortable waterproofing material that protects structures from the harmful effects of water. It provides an effective solution for critical areas such as foundations, retaining walls, basements, gardens, terraces, and roofs, as well as for bridges and viaducts that are exposed to heavy loads. Thanks to its polymer-reinforced structure, bituminous membrane offers high durability. It is produced with polyester and fiberglass reinforcements, which provide different levels of tensile, tear, and break resistance, enhancing flexibility and strength. Additionally, it offers a practical and long-lasting waterproofing solution due to its easy application.

- TS 11758-1:"Polymer-bitumen sheets – For waterproofing – Applied by torch welding – Part 1: Specifications"
Essential Waterproofing for Structural Protection
In reinforced concrete structures, steel reinforcements exposed to water undergo corrosion, rapidly losing their load-bearing capacity and reducing earthquake resistance. Studies show that in buildings without waterproofing, the load-bearing capacity can decrease by 50% within just five years, and steel reinforcements may completely lose their function within 24 years. Therefore, the use of bituminous membrane in foundations, roofs, and terraces is of vital importance. Effective waterproofing applications extend the lifespan of structures while protecting load-bearing systems and enhancing earthquake resistance.
Safe Structures
The 2018 waterproofing regulation, which made waterproofing mandatory in construction, was a significant step toward creating safe buildings. However, risks persist due to deficiencies in older structures. According to the Ministry of Environment, Urbanization, and Climate Change, 6 million buildings in Turkey are at risk, and 2 million need urgent transformation. In Istanbul alone, 600,000 buildings require rapid strengthening. Constructing earthquake-resistant buildings is not a choice but a necessity, and membrane application plays a crucial role in effective waterproofing.
