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%.
Lake bank stabilization at Vivid Shores
At Vivid Shores in Bonita Springs, Florida, PROPEX® Armormax®, MIRAFI® FW403 and MIRAFI 140N stabilize lake banks exposed to wind-driven wave erosion. Completed sections are performing as designed.
Monarch Dunes is a resort community that offers residents golf, recreation, and a community vineyard. During construction, a drainage channel was installed in the vineyard to convey surface runoff from the housing development to detention storage basins. Due to the steepness of the slope, the amount of flow, and the erodible sandy soils, the channel severely eroded and failed. The developer needed a solution to provide long-term stabilization of the channel.
Initially hard armoring solutions were considered, but the developer wanted a more natural aesthetic. A combination of PROPEX® Armormax® and PROPEX Pyramattress®, an engineered mattress system that uses PROPEX Pyramat® 75 HPTRM to construct a geosynthetic/soil/rock composite for protection of channels, slopes, and spillways, was selected. The combined system was designed to provide erosion control on the side slopes and scour resistance in the channel bottom caused by the constant flow of water.
Unlike hard armoring technologies, PROPEX Pyramattress components are corrosion resistant and promote vegetation, allowing for an increased design life that is environmentally friendly.
The installation of this project was quick and easy because PROPEX Pyramattress and PROPEX Armormax are more easily transported than hard armoring solutions. The systems also install faster than convention methods, saving time and money.
