HDPE geomembranes have a high dense cell structure making them an ideal choice for containment applications. Its low cost, excellent chemical resistance, and excellent weathering properties further promote it to be the world`s most popular geomembrane.  HDPE geomembranes are produced in various thicknesses, textures, and standards of performance. Penteco`s HDPE series meets or exceeds GRI`s GM-13 specifications. With any geomembrane it is crucial to narrow down the design parameters, and then match it with the best suited product. When comparing smooth vs textured surface, one must consider the parameters surrounding the coefficient of friction, load transfer, and the installation time-frame.

When it comes to the mechanical properties, the smooth sheet will always fare slightly better, however, most of these variations do not pose an impact on the quality or longevity of the liner system. Design engineers must consider going with a thicker liner if they are concerned with both the mechanical properties and the need for a textured surface.

Monofilament geotextiles are manufactured by weaving extruded, prestressed and round strands of polypropylene. These are characterised by greater strength & higher modulus, owing to the extrusion and the pre-stressing of its fabric. They also provide better drainage & filtration than the slit film woven geotextiles, and exhibit low potential for clogging. They are typically used for applications requiring both strength and filtration.

Geonets are made from high-density polyethylene (HDPE) extrusion strands intersecting at different angles and spacings creating a mesh-like interconnected set of ribs. It`s main function is to provide planar drainage for liquids or gases. Most geonets are biplanar thus allowing the transmissivity of fluids in any direction.
