Full Face/Partial Face/Treatment of Joints and Cracks

Deterioration of concrete dams can be due to shrinkage, creep, freeze/thaw cycles, loss of strength under permanent and repeated loading, aggressive water, thermal loading and swelling caused by chemical reactions (alkali-aggregate and alkali-silica reaction, sulfate attack) etc. Deterioration results in water infiltrating the dam body with consequent increase of uplift forces, reduced stability and accelerated further deterioration.

SIBELON® geomembrane systems prevent/stop leakage, reducing or preventing uplift forces, bridge cracks and opening of joints, protect the concrete against freeze-thaw deterioration and aggressive water, assist in retarding swelling and protect against chemical attack, and can withstand seismic events.

Surface preparation required for the installation of SIBELON® geomembrane systems is minimum.
