A coal-fired power plant owned and operated by a regional utility company located in Kentucky required the construction of a new impoundment and improvements to multiple existing impoundments to handle the residual cooling and run-off water. A multi-layer geosynthetic liner system was needed to bring the power plant in compliance with new federal regulations.
Hallaton Environmental Linings was contracted to provide and install a multi-layer geosynthetic liner system. The owner was required to install a geosynthetic liner system consisting of a GCL installed on a prepared subbase, 40 Mil LLDPE textured geomembrane liner, 12 oz non-woven geotextile and a 6” fabric formed concrete system filled with highly fluid concrete mix. The final layer of the installed system was a fabric formed concrete layer. Hallaton’s crew installed on average 120 cubic yards of the highly fluid concrete mix on a daily basis. The completed system will provide added protections to the environment and allows the owner to maintain the upgraded impoundments in a more efficient and cost-effective manner.
