HDPE (High Density Polyethylene)
With Proven results in New Zealand since 1964. Polyethylene liners have an estimated projected life expectancy more than 150 year.
HDPE Geomembranesexhibits outstanding chemical resistance, exceptional ultraviolet light resistance and excellent tensile properties.
HDPE Geomembrane is one of the most commonly used liner. It provides a tough, durable lining system with a wide variety of applications a thickness as well as being available in a smooth or textured surface.
LLDPE (Linear Low Density Polyethylene)
With similar properties to HDPE, LLDPE geomembrane has high elongation properties making it ideal for applications where differential settlement may occur.
Geotextiles are used as a protective layer either above or below the Geomembrane Lining System.
This is used to reduce puncturing of the membrane in rough sub-grade conditions or placed above the membrane for protection when cover materials are placed on top.
Geotextiles rolls come in a range of thickness to suit a variety of applications.
GCL (Geosynthetic Clay Liner)
GCL’s utilise a layer of Sodium Bentonite clay between two geotextiles. The geotextiles are needle punched together through the Bentonite to ensure high, long-term shear strength. This provides an exceptional hydraulic barrier.
This lining system requires simple on-site overlapping of panels, no welding required and installation is cost effective.
Polylock is a HDPE made strip insert. These strips are welded together to form either a continues loop or attachment point which is designed to be cast in the concrete during construction. The HDPE Geomembrane is then welded to the Polylock creating a seal between the liner and the concrete.
