Canals
- Applications
- Coletanche advantages
- Other characteristics
- Navigation, fret canals and waterways,
- Hydroelectric power plant supply pipes,
- Irrigation canals,
- Distribution canals.
- Flexibility: enables transverse anchoring, ideal to counteract swelling, facilitate leak detection by dividing the canal into sectors.
- Wind resistance up to 70 km/h without anchoring: limit lifting and tearing when the canal is partially or completely empty.
- Excellent Manning’s coefficient: the geomembrane remains in permanent contact with its substrate, without creases. It is resistant root or vegetation penetration thanks to the Terphane film on the underside.
- High density (1.22), it can be immersed: underwater repair is therefore possible by bonding the joints with bituminous adhesive.
- Potability and compatibility with drinking water: All Coletanche geomembranes are NSF ANSI 61 certified by NSF international.
- Easy to install: only one layer is efficient, no need a protective layer.
- Excellent performances over time, even in exposed conditions.
- Long term mechanical (tension, puncture, elongation) and chemical (leaching, acid, UV, gas) resistance
- Compatible with all types of materials (concrete, steel, PVC, etc) by sealing or gluing.
- Dimensional stability: no sensitive to expansion phenomena and stress cracks.
