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.
Jefferson Coal Slurry Impoundment Closure
In Jefferson County, Alabama, MIRAFI® CR440 was used with CCR fill to create a reinforced construction platform over soft fine coal refuse, supporting safe equipment access and efficient coal slurry impoundment closure.
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.
Brookshire-Katy Drainage District (BKDD) maintains a drainage channel that runs along Stalknecht Road in Waller County, Texas. Extreme stormwater flows caused by Hurricane Harvey caused the roadside drainage ditch to experience erosion and slope instability, reducing the channel’s capacity.
The severe erosion and reduction in channel capacity prompted BKDD to pursue permanent erosion protection.
An early phase in the design process used rock filled gabion baskets to armor the channel, however, the design engineer wanted a more economical and environmentallyfriendly solution. Gabion baskets require the removal and transportation of excavated material from the site, but PROPEX® Scourlok® allows the reuse of on-site soil to fill the units.
Stakeholders selected PROPEX Scourlok for the remaining phases of the project because it was a more cost-effective solution. PROPEX Scourlok is a stabilization system that features rigid and interlocking cells armored with erosion protection from a highly UV stabilized High Performance Turf Reinforcement Mat (HPTRM). The system is engineered to provide a vegetated, gravity wall system that resists sliding and overturning for up to 75 years.
The design included an eight-foot wall, comprised of two tiers of PROPEX Scourlok that spans 500 feet along the eastern side of the channel. The design also included 300 square yards of PROPEX Armormax® along the top of the channel.
