EPDM geomembrane

EPDM is a highly elastic waterproof membrane, with very good elongation (elongation of over 300%, which helps the membrane to take the shape of the insulating substrate) and temperature-independent properties (it retains its elasticity even at temperatures below -45°C, allowing it to adapt to large temperature fluctuations).

EPDM contains UV and erosion protection while being completely safe for the environment (ISO 14001). The lifetime of a geomembrane is over 50 years.

EPDM rolls are available in widths of 6,1; 9,14; 12,19 and 15,24 m. Each roll is 30.48 m long.

EPDM geomembrane, like any other membrane, needs protection against mechanical damage. Therefore, the geomembrane surface must be protected with a layer of geotextile or fine sand. Do not place gravel or coarse gravel on the surface of the membrane, as sharp-edged stones can damage the membrane.

EPDM geomembrane panels are joined together and membrane penetrations are made using a special Elevate tape. The panels of the geomembrane are glued together using a special double-sided tape between the joints. The pipe and other geo-membrane penetrations are made using a raw rubber-based tape.

At the top of the shore, the EPDM geomembrane will be anchored in an anchor trench (depth approx 15-20cm). For smaller ponds, an anchor trench is not necessary – the top edge of the membrane can be hidden in soil, under stone lining, etc.

For large isolated areas, it is advisable to install a circular or flat gas and water drain under the geomembrane.
