Teranap 331 2M/4M

Prefabricated Bituminous Geomembrane


In the 1970s, Siplast developed the world's first bituminous geomembrane, Teranap.  Since then, Teranap has proven itself as a reliable, practical, and durable liner for concrete and earthen canals, settling basins, embankment stabilization, dams, mine waste containment, waste water storage, reservoirs, and ponds.


Siplast Teranap 331 is a high performance elastomeric bituminous geomembrane. Unique among waterproofing materials, Teranap 331 combines SBS polymer and the highest quality asphalt with puncture resistant polyester reinforcements. This special combination dramatically increases performance in key areas such as mechanical properties, cold flexibility, elasticity, and resistance to the elements. The result is a geomembrane that is able to consistently maintain its integrity in an ever-changing, inconsistent environment.
