Project Overview

In September 2022, 1,700m² of CC Hydro^™ GCCB was installed to provide containment and hard armour protection for a newly installed tertiary containment lagoon in Kinsgbury, England.

An overflow lagoon was required for the terminal as a number of tanks at the site were only operating at ~60-70% capacity due to secondary containment bunds around the tanks not being at a suitable size to contain a spill if the tanks were at full capacity. A number of options were considered, however, the availability of unused land adjacent to some tanks was chosen to install a new overflow lagoon.

Lagoon being excavated, cut into a uniform profile, CCH8^™ laid transversely, CCH8^™ deployed using a spreader beam

1700m²

of CCH8^™ used to line the drainage channel

14 Days

to install including the excavation of the lagoon

300m²

of CC5^® was used to provide protection to the outer slopes

Solution

To ensure that the lagoon prevented harmful petrochemicals seeping into the ground a number of lining solutions were considered. CCH8^™ was chosen as the material to line the lagoon, providing both containment and hard armour protection.
