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.
GSE HD geomembrane lined salt ponds ensure long-term brine containment
GSE® HD geomembrane lined over 3.4 million m² of evaporation ponds to prevent brine seepage under extreme heat and UV exposure. This continuous barrier eliminated salt discharge and protected the surrounding environment.
Ensuring secure tailings containment at Saudi Arabia’s Umm Wu’al Phosphate Project
Solmax supplied 900,000 m² of double-sided GSE® HD FrictionFlex geomembrane for Maaden’s Umm Wu’al tailings ponds in Saudi Arabia, meeting strict quality controls and ensuring flawless containment in extreme conditions.
The Government of Mauritius, through the Road Development Authority, initiated the construction of the A1-M1 Link Road to create an effective and efficient road network that supports socio-economic development. The project aimed to improve traffic flow, reduce congestion time and costs, enhance road safety, and provide high-quality infrastructure.
At the junction of the Chebel Bridge and A1-M1 Link Road, the road's embankment was supported by an L-shaped concrete wall. To address the need for drainage, a system was constructed to evacuate ground and pore water. This drainage system effectively transported water along the wall to the drainage pipe, protecting the wall from direct contact and potential damage.
Two drainage systems were considered: conventional gravel drains and geosynthetic drainage mats like FABRINET® DC 401 E. Gravel drains, although commonly used, posed challenges due to the cost and transportation of gravel from natural resources. In contrast, drainage mats provided a practical alternative. With comparable drainage capacity and easier installation, they offered economic benefits for both the project owner and contractor.
FABRINET DC 401 E, a geocomposite, consisted of a geonet and a filter geotextile. The geonet is made from high-density polyethylene (HDPE), and the filter geotextile from polypropylene (PP). These materials exhibit low compressibility, enabling high discharge capacity even under heavy loads. They are suitable for various surface drainage applications.
Both the geonet and filter geotextile demonstrated excellent resistance to chemicals and biological factors, allowing their safe use in contact with soil and construction materials such as concrete.
