FLAGON® GEOP AT 1.2, 1.5, 1.8 and 2.0 mm
FLAGON GEOP/AT is a TPO thermoplastic membrane dimensionally stabilized with a sheet of glass fibre, specifically designed for waterproofing tanks and containers used for drinking water. This membrane is also recommended for projects of natural pools.
FLAGON® GEOP AT has different physical-chemical properties
on each side: - the upper surface (green) is treated against UV rays -
the underside (black) is highly resistant to puncture and perforation by
roots Any tears in the green upper layer of the membrane can be seen immediately
due to the difference in colour between the two sides. The raw materials
used to produce FLAGON® TPO membranes are obtained by mixing modified
polyolefins with different additives by means of a process that creates
a paste which is later transformed into granules.
This combination gives the synthetic membranes the following advantages:
- high resistance to ageing and weathering,
- the elastomer component provides suppleness and flexibility with high mechanical and chemical resistance,
- compatible with drinking water,
- resistant to aqueous solutions of sodium hypochlorite,
- high resistance to weathering and UV rays,
- insensitive to freeze-thaw cycles,
- high mechanical resistance,
- high puncture resistance,
- resistance to perforation by roots,
- environmentally-friendly and non-toxic.
FLAGON® GEOP AT is a TPO thermoplastic geomembrane reinforced with a glass fibre mesh, specifically designed for waterproofing tanks and containers used for drinking water. It is particularly suited to hillside dams and structures subject to high mechanical stress. This geomembrane lining can contain salt or fresh water and lowconcentration liquid chemicals. The strips are usually welded together by applying hot air using a manual or automatic welder with a minimum a 30mm overlap. They can be double-welded with a central canal using a wedge welder. FLAGON® GEOP AT is compatible with all the accessories and membranes in the FLAGON® TPO range.
