Great job Testdrill!
After two major landslips close to our house in March '16 we engaged Testdrill to construct two terraced retaining walls. Unfortunately a very wet winter and spring prevented work until November, except for the testing process on the site. When work did commence (and I stress the delay was no fault of Testdrill) it was completed quickly, with minimum disruption to our household routine. The resulting walls and terraces are very strongly constructed, with great attention to detail, and are very attractive as well as totally functional. Great job Testdrill!!
