Containment Solutions, Inc. (CSI) Fiberglass Manholes

Fiberglass Manholes While the ultimate life span of a fiberglass manhole would be dependent on the types of chemicals present in either the ground water or the wastewater, it is possible to state that fiberglass will far out last concrete in virtually every application. This benefit is immediately perceptible to owners that have had problems in the past with the degradation of traditional concrete manholes. Lightweight and structurally sound to withstand HS-20 axle loads, fiberglass monolithic manholes from Containment Solutions resist the effects of hydrogen sulfide gas and minimize the amount of infiltration and exfiltration through the treatment system. Our manholes offer an economical and effective solution to your wastewater system needs. CSI Manholes and Wetwells come with a 20-year structural and corrosion warranty, the most comprehensive warranty in the industry.
