ROWAD is manufacturer of widest selection of HDPE & LLDPE Geomembrane by innovative three-layer Co-extrusion facilities with highest Quality of Polyethylene Resin . Carbon black & antioxidant added for best UV protection and for long life.
Our facilities are able to produce thickness ranges 0.5 to 3.0 mm, width of 8 Mtr Rolls which reduces the installation time & cost.
We produce liners with Smooth/Smooth , Smooth/Texture, Texture /Texture, & white/black surfaces.
All RIG geomembranes are manufactured to meet or exceed the test values, frequency of testing & functional requirements of the GRI GM13 /GM17 specification which was established by Geomembrane Research Institute (GRI), USA.
HIGH DENSITY POLYETHELYNE (HDPE)
Chemical Resistance: HDPE has an excellent chemical resistance and is not threatened by typical solutions or hazardous waste.
Ultraviolet Resistance: HDPE's resistance to UV exposure is further enhanced by the addition of carbon black. Additionally, with the absence of plasticizers, volatilization is not a problem.
LINEAR LOW DENSITY POLYETHELYNE (LLDPE)
Flexibility: In addition to UV and chemical resistance, LLDPE geomembranes exhibit a high degree of flexibility. Greater flexibility helps in installing LLDPE around complex shapes and corners. It is much more flexible than HDPE.
Puncture Resistance: High puncture elongation properties make LLDPE liners ideal in applications where conformances to sub-grade irregularities increase the possibility of puncture.
TEXTURED GEOMEMBRANE
High Coefficient of Friction: Rowad co-extrudes its textured liners with nitrogen to provide increased friction angles for higher stability on steep slope applications. This increased friction significantly reduces slippage, allowing for a more reliable install. |
