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 Clark International Airport in the Clark Freeport Zone is making progress in the aviation industry with its modern passenger terminals. It serves as a northern gateway and an alternative to the main airport in Metro Manila.
As part of the project, an artificial waterway is being created to collect water runoff within the airport. However, the abundance of lahars (thick debris slurry) in the area poses a significant concern for erosion in the waterway. To address this, a revetment structure is needed for erosion protection.
To protect against slope erosion, we proposed using GEOTUBE® SFM for the waterway section. This solution offers excellent robustness, abrasion resistance, and durability. A special substrate integrated into the upper surface of the sand-filled mattress promotes rapid vegetation growth, ensuring long-term vegetation cover.
Before installation, a layer of Polyfelt® TS 60 non-woven geotextile is placed on the slope to separate and prevent scouring during hydraulic filling of the sand-filled mattress.
The GEOTUBE SFM rolls are then laid on the slope, running parallel in tubular sections with a 1:1 slope (45-degree angle). The mattresses are hydraulically filled with sand through top openings. A small hopper is used to introduce the sand, which is washed down with water. Adjacent rolls are joined by seaming on-site.
Finally, the sand-filled mattresses are anchored in a trench at the top of the slope.
The GEOTUBE SFM serves as revetment for the entire waterway network at the new Clark Airport Terminal.
The rolls are easy to transport, and installation is quick and straightforward, requiring simple equipment. Skilled labor is not necessary. This erosion protection solution offers long-term effectiveness due to its high robustness, durability, abrasion resistance, and UV resistance. A site revisit showed significant growth of natural vegetation covering the sand-filled mattresses.
