SaarGummi has been producing pond lining systems for over 40 years. Our experience with watertightness contributes to projects such as water retention for ponds and swimming pools, and dike ponds. The special EPDM rubber material stays elastic, root resistant and resilient to heat and frost. NovoProof® sheets and membranes are eco-friendly, prevent the drainage of water and support eco-systems through their maintenance free durability.
