Okertalsperre (D) – Sealing under water
The Okertalsperre, completed in 1956, has become leaky over the years in the entire area of the construction joints. The PROOFMATE FD System was used for efficient renovation – for bonding even on wet substrates, even under water.
PROOFMATE® FD Sealing membrane based on EPDM (ethylene propylene diene monomer). Thickness: 1 mm.
- High elasticity even at low temperatures
- High compressive strength due to vulcanisation
