EPDM membrane is a synthetic waterproofing membrane made from ethylene-propylene-diene rubber, which is used to protect structures against water and moisture penetration. In the wellness sector, it is mainly used for insulating cooling tubs, ponds, pergola roof structures or as a protective layer beneath technical components. The material is extremely resistant to UV radiation, temperature fluctuations and mechanical stress. EPDM retains its elasticity even after decades of use, which minimises the risk of cracks or leaks. Unlike cheap PVC membranes, there is no rapid degradation or loss of elasticity. It is a standard technology used in the construction industry and professional waterproofing applications.

Advantages of EPDM membranes

• Long-term protection against water ingress: The membrane forms a reliable barrier that protects the structure from moisture and damage.
• Exceptional durability and UV resistance: EPDM can last for 30–50 years without any significant deterioration in its properties.
• High elasticity and crack resistance: The material adapts to the movement of the structure without compromising its seal.
• Minimal maintenance requirements: Once correctly installed, it requires virtually no maintenance throughout its entire service life.
