Our own design and patented underground tank system is constructed using a combination of steel and prestressed panels with all joints sealed using an approved sealant.

The system is a quick and cost effective way to construct an underground tank. It is a tried and tested system and can be installed successfully by any competent farmer or contractor.

The Underground storage tanks can either be left open as a lagoon, covered with slats or if a suspended floor covered with slats, cubicles and passage covers.

We are able to supply underground tanks in any size and various depths up to 2.4m (8’) deep. The tanks system is structurally certified and approved by the statutory environment agencies.

They are suitable for the storage of slurry, sewage or water.
