The watertightness in concrete structures is provided by the concrete itself, but due to the concrete’s characteristics, the likelihood of developing cracks and other leaking pathologies requires the waterproofing treatment of the upstream side. On the other hand, masonry structures are even more critical in developing leakages and therefore require an effective waterproofing system.
The KÖSTER TPO Aqua 2.5 Geo is an extremely robust TPO membrane made with the highest quality polymers and special additives that provide a very flexible, but at the same time very strong, membrane. The membrane features a 2.5 mm homogeneous PE-based TPO layer with a factory-embedded 500 g polyester fleece geotextile on the underside, providing additional protection against irregularities and protrusions which, under water pressure and weight, could otherwise compromise the integrity of the membrane.
This special membrane allows one of the fastest waterproofing application methods available, both for new structures and for existing structures requiring renovation. It is applied by mechanical fixation to the structure, without the need for surface preparation or removal of existing coatings, and offers high stability even on steep slopes as well as long-term durability against atmospheric agents.
The use of KÖSTER TPO Aqua 2.5 Geo reduces almost to zero the negative effects of cracks, substrate erosion, and vegetation growth on concrete or masonry surfaces.
This special membrane is a truly environmentally responsible product, completely free of plasticizers and other volatile compounds, and helps to save millions of cubic meters of water with maximum safety and respect for the environment.
