Trees which in the past had to be removed because of their damaging effect on foundations, can now remain and exist quite happily along side of the buildings, without causing any problems underground. Root Barrier keeps the roots out and the moisture in. Due to new developments in the product and installation system, costs have been vastly reduced, and the requirements for heavy earth works with heavy machinery removed.
