No-dig technology or relining is the fastest and most cost-effective way to repair a damaged drain or sewer. It involves installing a lining which bonds to the inside of the pipe — creating a pipe within a pipe — so that the integrity of the drain or sewer is restored, with minimum disruption.
From big to small
Drain relining can be carried out on pipes from as small as 100mm diameter right up to 1.5-metre culverts and, depending on access and logistical considerations, in single lengths or in a series of shorter, overlapping liners. Patch liners can be installed in pipes as small as 60mm diameter up to 1.2-metres, which is the size of the largest packer currently available (see glossary below).
An industry leader
Lanes adopted no dig or trenchless technology back in the 90s when it was relatively new. As a result, we are now firmly established as a leading reline specialist in the UK. Our team trials new materials and techniques and works closely with international manufacturers and industry bodies. We regularly hit the headlines for our pioneering projects and currently hold the record for installing the longest single liner in the UK.
Lanes has accomplished much in this specialist field of drain relining in a diverse range of projects and places: major schemes for water utility companies relining crumbling, brick Victorian sewers; strengthening drains as enabling works for Manchester’s tram network; rehabilitating pipes running beneath suspension bridges; renovating drains and sewers running alongside canals or rivers; repairing drains in Sites of Special Scientific Interest (SSSIs) which have to be renovated without destroying the surrounding land — to name just a few.
Local drain relining expertise
Equipped with the latest technology and equipment and staffed by an unrivalled team of experts, our Sewer Renovation Division operates throughout the Lanes’ network of depots nationwide, so you have access to our specialist drain relining service wherever you are in the country.

Drain relining jargon explained:
The method of repairing a drain or sewer by creating a new pipe within the existing one, without the need to excavate.
The ‘tube’ of material (often special felt or a fibre glass matrix) manufactured to a specific length and diameter for the renovation, then installed in the sewer or pipe to create a new pipe inside the damaged one.
The liner is impregnated with resin prior to being installed into the pipe. The resin then ‘cures’ to harden, creating this new inner pipe.
The method by which the impregnated liner is installed. The tube liner is forced through the damaged pipe by water pressure. At the same time, the water turns it inside out pushing the resin impregnated side outwards to adhere to the inside of the pipe, sewer or drain.
Various methods are used to cure the resin-impregnated liner so that it hardens — hot water, ambient, or UV lighting.
Similar to a liner, but used for isolated defects or small damaged areas within a drain, sewer or pipe.
Used to position a patch repair liner and force it against the internal surface of the pipe to effect the repair.
Used to stop water ingress in manholes. Polyurethane resin is injected into the manhole where it expands to 40 times its original volume on contact with water, sealing the holes and cracks.
