GSE® HD geomembranes were placed directly over compacted soil subgrades to form a continuous impermeable lining for the canals.
The geomembrane liners were installed beneath a concrete layer, creating a protected barrier that limits seepage and improves durability.
The lining system was constructed to ensure stable interaction between soil, geomembrane, and concrete layers over the canal alignment.
Installation was carried out across large canal sections, requiring consistent placement methods over millions of square meters.
Single-sided textured GSE® HD geomembrane was applied to balance anti-slip performance with material efficiency beneath concrete linings.
Double-sided textured GSE® HD was used where enhanced interface friction was required to reduce movement during construction.
Omega Mine extends AMD treatment capacity with dewatering
At Omega Mine in West Virginia, GEOTUBE® GT500 units help the West Virginia Department of Environmental Protection treat and dewater acid mine drainage from abandoned mines while supporting long-term capacity and compliance.
Dredging and reuse of contaminated sediments
Embraport used dewatered contaminated sediments as structural fill within its terminal platform, saving 400,000 m3 of imported material and reducing earthfill platform costs by 20% to 30%.
Remediation of contaminated marine sediments at Port Ouest, La Grande-Motte using GEOTUBE dewatering systems
Contaminated sediments were dredged from Port Ouest in La Grande-Motte and dewatered using GEOTUBE technology to support port modernization while meeting environmental requirements.
Large-scale irrigation canals constructed to support agricultural expansion in Egypt faced the persistent problem of water loss through seepage. In regions dependent on controlled water distribution from the River Nile, unlined or inadequately lined canals reduce hydraulic efficiency and limit the ability to expand cultivated land. To address this issue, a long-term canal lining program was initiated in northern Egypt, including the North Coast and New Delta areas, and in southern Egypt in the Toshka region. The project began in 2021 and is planned over a ten-year timeframe. The purpose of the works is to conserve water resources, improve canal performance, and support sustainable growth in agricultural areas by implementing a reliable lining system for new canals.
The core challenge was to prevent water losses across extensive canal networks constructed in varying geographic conditions while ensuring long-term performance. The lining system needed to function effectively beneath a concrete layer and over compacted soil subgrades, requiring stable interface behavior and resistance to movement during and after installation. The large surface area involved, measured in millions of square meters, added complexity to material supply and installation consistency over time. Achieving uniform quality across different construction zones and contractors was essential to ensure that the canals would perform as intended and deliver measurable water savings.
The adopted solution was the use of GSE® HD geomembrane liners designed specifically for canal applications. The system included 1.0 mm double-sided textured GSE HD geomembrane, supplied in quantities of approximately 2 to 3 million square meters, and 1.5 mm single-sided textured HDPE geomembrane, supplied in quantities of approximately 1.5 to 2 million square meters. These geomembranes were installed over compacted soil and beneath the concrete lining layer. The textured surfaces provide anti-slip performance, improving stability between interfaces and reducing the risk of movement during construction. The GSE HD lining creates an impermeable barrier that significantly reduces seepage losses, enabling more efficient use of water resources and supporting the expansion of agricultural land. Contractors involved in the project reported consistent material quality throughout the works, with no complaints recorded, reinforcing the effectiveness of the solution in addressing the core problem of water conservation in large-scale canal systems.
