When Traditional Sand Bunds Fail: A GEOTUBE Marine Solution for Land Reclamation
When traditional sand bund construction failed on an extremely soft marine clay seabed, GEOTUBE® Marine systems provided a stable containment solution that helped advance a land reclamation project for 112 acres.
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 Almacen River, located in Bataan, Philippines, is one of the major rivers in the area. However, it experiences annual flooding during the rainy seasons, causing concern for the residents of Orani, Hermosa, and Dinalupihan Bataan. This flooding is primarily due to severe siltation caused by a lahar deposit from the upstream river heading to Mt. Pinatubo.
To effectively address the issue of severe siltation, the Department of Public Works initiated the use of GEOTUBE®. These are deployed as silt depots at the river mouth and used to dredge the 2.5-mile (4.0 km) river, removing the lahar deposit and deepening the river channel. This allows for a greater volume of water to flow during the rainy season, helping alleviate the recurring problem of severe flooding in the surrounding municipalities of Hermosa and Orani, Bataan.
The Almacen River Improvement project utilizes GEOTUBE GT750M as riverbank protection. The dredged material from the river is used as filling soil for the river embankment and slope protection. By using GEOTUBE GT750M on-site, there is no need to source materials from off-site, saving time and resources. Additionally, the project includes the improvement of waterways leading to the Almacen River, diverting floodwaters away from farmlands in the villages.
The construction involves the placement of GEOTUBE GT750M, scouring apron, and protection geotextiles. These structures act as erosion-resistant revetment protection, with a primary function of serving as a mass gravity structure. The GEOTUBE GT750M is filled by hydraulically pumping a sand/water slurry through the filling ports. The fill material is a mixture of sand and water, allowing for easy flow. Water from the river can be used for this purpose. The GEOTUBE, being permeable, allows excess water to pass through the geotextile skin while retaining the sand within. The installed GEOTUBE GT750M acts as gravity-based building blocks for erosion protection along the river.
The use of GEOTUBE GT750M speeds up project completion, requiring less manpower as the installation process is fully mechanical.
