48 Inch Square Sump, Square Cover
Underground Enclosures and Transition Sumps
Our range of GRP/FRP containment systems can be used for pipework and cable transition chambers and to house underground pumps and other electrical equipment. Our systems comprise of a solid base chamber, frame and a flat sealed composite manhole cover, providing the perfect watertight solution.

GRP (glass reinforced plastic) also known as FRP (fiberglass reinforced plastic) is very strong, non corrosive and requires minimal maintenance during its working life. Chambers can be produced to be resistant to specific chemicals, by using a special resin during the manufacturing process. We can also add an anti-static material within the surface of the chamber, to ensure it is fully conductive. This makes GRP the ideal material to use for many industries and utilities.

Our covers are designed with a watertight seal and are flush with grade level, to prevent trip and fall injuries. Our ergonomically designed lifting handle (model FL7A), provides safe removal and replacement of covers, without risk of injury to the back and fingers.

Fibrelite produce high quality one-piece molded, semi-rigid components, with a smooth finish for easy handling during installation. Designed and manufactured to withstand high ground water pressure after installation for the lifetime of the site. The new fully conductive chamber is manufactured using the latest in GRP/FRP technology which ensures consistent wall thickness and quality.
