Soakaway Tank Installation
Ground Technology Group are expert installers of soakaway tank systems. Unlike attenuation, soakaways are designed to slowly disperse water into the surrounding ground via infiltration. We tailor every solution to your exact specification, installing any shape or system nationwide. Our service ensures efficient, compliant, and sustainable surface water drainage.
Gas Membrane Installation
We are UK-wide specialists in the installation of gas resistant membranes. Essential for safety on sites with ground gas risk, these barriers prevent the ingress of harmful gases such as radon and methane into buildings.
