Tunnel geomembrane TERANAP 431TP GTX

composite

Composite SBS elastomeric bitumen geomembrane fitted with factory-applied antipuncturing geotextile. The close factory-bonding of Teranap TP to an antipuncturing geotextile enhances its mechanical performance. Improved frictional resistance on the underlying substrate. Allows innovative methods of application of layered concrete above the Teranap 431TP GTX membrane, such as: extruded concrete applied voing slipform. shotcrete (fibre-reinforced concrete). Successfully applied on new and refurbished canals. The use of Teranap 431TP GTX dispenses with the use of protection board as a mechanical protection when used in tanking. Repairs of accidental leaks can be carrie. MAIN USES Waterproofing of sloped areas: canals, reservoirs, embankments. For new or refurbished works. For Tanking: the use of Teranap 431TP GTX dispenses with the use of protection board as a mechanical protection. DESCRIPTION Teranap 431TP GTX is a Teranap TP geomembrane with a factory-bonded geotextile comprising the same elastomeric compound and reinforcement as Teranap 431 TP. The close bonding of the membrane to an anti-puncturing geotextile enhances the mechanical performance of Teranap TP. The underside, covered with polyester film, is highly resistant to root penetration. The surface is coated with silica sand. Teranap 431TP GTX is a Siplast patented product.
