No-Dig (Repairs without excavation)

Where defects are localised in a small area, this can be ‘’patched’’ to produce a permanent high quality repair. Patches are applied by coating a fibre-glass mat with epoxy resin. The mat is then wrapped around an inflatable packer and pushed into position. The packer is inflated and the resin left to cure.

Section Lining – Where the drain is damaged along its length, the whole section can be lined. It involves the insertion of a lining ‘’sock’’ impregnated with a polyester resin fibre along the length of the damaged drain. It is then moulded into place using air or water pressure and left to cure. The result is a new fibre reinforced pipe within the old damaged pipe.

RH Group (UK) Ltd has a Vactor unit which is specially designed to meet the demands of fast clearance of pipes, culverts and sewers from 100mm upwards. This unit is designed to clean the large, deep and most inaccessible of heavily silted drains.

It operates at speeds of up to six times that of conventional jetters. However, high flow rates and variable low pressures mean there is no risk to the structural integrity of the drainage system.
