Pouygostar has 10 years experience in developing and manufacturing Elastomer gaskets for the tunneling industry. They are made of sophisticated and high-grade rubber compounds quality to meet the high standards and requirements with regard to durability and project life expectancy.

A segmental lining made up of reinforced concrete segments possesses numerous longitudinal and T-joints. These joints have to be sealed against the maximum water pressure that affects the tunnel tube. This takes place by means of Elastomer gaskets, which are installed in the continuous grooves of the segments.
Elastomer rubber gaskets are used to provide long term water tightness in joints of concrete segments.
Gaps and offsets between segments are tightened by compression of a pair of gaskets
