About Us


Based in Kidwelly, we are a family run business that provides specialist ground investigation and develop Sustainable Drainage Systems (SuDS).


With over 30 years experience in the construction industry, we pride ourselves on being a one stop shop for Sustainable Drainage Approval Body (SAB) applications with our in house engineering team.

We can also undertake complex groundwork projects such as raft foundations, screw pile foundations and underpinning.
