INSTALLATION METHOD STATEMENT

Our Geopoly team of skilled and experienced Technicians are committed to provide efficient and reliable installations service. Installations require detailed planning and co-ordination with the Project Owners, Consultants, Engineers, Contractors, Applicators and Site Personnel to ensure special attention and timely completion of their lining projects.

We provide professional and comprehensive advise on the proposed Pond, Cell, Tank or Site preparations including advise on earthworks, perimeter anchor trench preparation, sub grade, anti-floatation sub-soil piping systems and other project preparations details.

HDPE geomembrane liners can be installed quickly when compared to concrete, clay or other spray-on membrane liners. Geomembrane liners are easily unrolled and laid over the prepared surfaces and seamed by our trained technicians or authorized applicators. Each panel deployed and seamed is recorded to indicate the roll identity, date, time, equipment, supervisor and other details.

HDPE geomembrane liners are welded by Fusion Weld method using a Hot Air or Hot Wedge Welding machine for long linear welds. The Hot Air or Hot Wedge Welder creates a fusion weld by heating the overlapped liner surfaces, with a pair of rollers pressing them together while in molten state to result in a permanent bond.

Specific areas such as sumps, pipe penetrations, concrete structures, fittings and accessories shall require special termination techniques. Non-linear seams, roll ends, pipe penetrations sumps, patches, corners or anywhere it is impractical to use a Hot Air or Hot Wedge Welder are welded by Extrusion Weld method using an Extruder Resin or Extruder Rod Gun. Folds at wall edges are neatly trimmed, overlapped and welded by the extrusion weld.

Any minor cuts, punctures or repairs are patched by a Hand Tool Hot Air Blower and may be further reinforced by the extrusion weld.
