No-Dig & Trenchless Drain Repair

No-Dig Repair Methods We Use

CIPP lining (cured-in-place pipe) is the most widely used no-dig method for commercial drainage. A flexible resin-saturated liner is inserted into the existing pipe, inflated against the pipe walls, and cured — by UV light, steam, or ambient cure depending on the liner system. Once cured, the result is a continuous, jointless structural pipe inside the host pipe. CIPP is suitable for most commercial drainage from 100mm to 1,200mm diameter, including clay, concrete, PVC, and cast iron. Liners carry a 50-year design life.

Patch lining addresses localised defects — a single cracked joint, a root ingress point, or a short section that does not warrant full-length lining. A pre-formed liner is positioned precisely over the defect and inflated. It is significantly more cost-effective than full relining where the rest of the drainage is in good condition. Pipe bursting is used where the existing pipe needs to be replaced entirely rather than relined — a bursting head fractures the old pipe outward while simultaneously pulling a new pipe through. This is the right solution where pipes are severely deteriorated but the route is otherwise suitable.

Why No-Dig for Commercial and Industrial Sites

The case for no-dig on commercial sites is not simply about convenience — it is often the only practical option. Drainage beneath warehouse floors, under car park tarmac, across active loading bays, or below mechanically strengthened yard surfaces cannot be excavated without significant operational disruption, reinstatement costs, and potential liability for damage to adjacent infrastructure. No-dig relining is completed through existing manholes and access chambers without opening a trench.

On occupied premises — retail, hospitality, healthcare, office buildings — the absence of open excavations removes the safety, public liability, and reputational risks that come with traditional repair. There are no spoil piles, no temporary road closures, no reinstatement patches. The site returns to normal operation far sooner. For facilities managers under pressure to limit contractor presence and minimise disruption, no-dig is the standard commercial repair approach wherever it is technically viable.

How Long Does a No-Dig Drain Repair Last?

CIPP liners are designed to a 50-year minimum service life under BS EN ISO 11296-4 and equivalent standards. In practice, liners installed 40 or more years ago are still in service. The liner creates a fully structural new pipe independent of the host pipe — it does not simply seal cracks or slow deterioration. Once cured, the only mechanism for failure is external damage that the host pipe itself would be equally subject to.

Patch liners carry equivalent design lives when correctly sized and installed. Pipe bursting replacement pipes are typically new HDPE, which has a similarly long service life. Unlike chemical drain sealing products, structural liners are permanent solutions. They are not affected by normal jetting pressures or root intrusion — roots cannot penetrate a cured CIPP liner. Post-repair CCTV verification confirms the installation is correct before the job is signed off.
