Drain relining is a cost-effective and no-mess alternative to traditional drain repairs. Our non-intrusive methods will ensure your drains are back to perfect working condition in no time, and will remain free flowing for years to come
Relined drainage pipe
This is a method of repairing drains and sewers by inserting a sleeve inside the pipe which once cured adds strength to the pipe and also by making it watertight, increases flow. Any size of pipe work can be repaired using this method. Hot cure and ambient cure methods are used on both Polyester and Epoxy resin. This method of repair is the most financially economical.
A resin impregnated felt is pulled into place and inverted using either water or air. Upon curing, the inversion tube is withdrawn and this creates a pipe within a pipe. If there are any incoming lines these can be exposed using a lateral cutter.
How is the liner installed?
A resin impregnated felt tube is inverted or dragged into the damaged host pipe. A calibration tube is then usually used to inflate and compress the wet out liner to the host pipe to form a pipe within a pipe. The resin is cured by a chemical process, and heat. Once cured in place, the calibration tube is removed; and the drain is then formed and watertight.
Drain Doctors Lining Process restores structural integrity to your damaged drain pipes.
Localised patch repairs
Typically used in areas where traditional excavation is difficult or with awkward access, localised patch repairs are a fast, cost efficient method of rehabilitating blistered pitch fibre or crushed pipework in diameters of 100 to 450 and to a length of usually 1 metre. Remedial work can include re-forming the pipe if necessary and then installing the patch liner.
