IKON recently completed a stabilization, cap and cover project associated with over 8 acres of low-strength, saturated petroleum waste basins in an active petrochemical plant along the Texas Gulf Coast.
A series of 4 waste basins had been consolidated, the subgrade strengthened, and capped with compacted fill prior to installing a multi-layer ClosureTurf system. The project consisted of utilizing earthen sumps, bleeder trenches and stabilization reagents along with high-strength geotextiles and geo-grid to strengthen the subgrade. As the subgrade was completed, IKON utilized approximately 45,000 cubic yards of onsite borrow soil along with approximately 15,000 cubic yards of import clayey fill to build and shape the compacted earthen cap.
As the earthwork for each of the basins received compaction and design certification, IKON worked with a third party liner installation company to install a geocomposite, 60mil textured HDPE liner, gas vents and ClosureTurf system. Along the outer perimeter of the combined basins, IKON installed geotextile and stone in order to stabilize the outer slopes. An outfall extension was installed and routed a county ditch completing the flow through design of the capped basins. The dewatering and subgrade stabilization activities extended throughout the winter months requiring dedicated and deliberate work sequencing.
