Sump Pit Waterproofing at a Kasoa Filling Station — How We Stopped Groundwater From Contaminating Fuel

CASE STUDY · COMMERCIAL WATERPROOFING

Kasoa · popular filling station · groundwater ingress into fuel dispenser sump pit · completed without interrupting operations.

A popular filling station in Kasoa had a serious problem. Groundwater was pushing up from below — through the concrete of a fuel dispenser sump pit — pooling around the fuel plumbing. Left unfixed, water in the sump would eventually reach the dispenser lines and contaminate the fuel stock. NPA compliance issues. Customer complaints about bad fuel. In the worst case: station shutdown.

This is the exact problem most Ghanaian waterproofing contractors get wrong. It's not roof waterproofing. It's not spray-on paint. Sump pit waterproofing at a filling station is a specialized commercial job that requires understanding hydrostatic pressure, fuel resistance, and negative-side application on damp concrete. Get any of those three wrong and the sealant fails within months.

Here's how Fest Ghana Limited solved it — with zero interruption to station operations.
