INSITU REPAIRS

At present, we undertake two different types of in-situ drain repair, essentially, structural lining and localised patch repairs. In-situ repairs do not require any excavation of pipe work and therefore serve as a cost effective and environmentally friendly alternative to drain replacement.

LINING (CIPP) Cured in place pipe

In simplified terms lining is a method of rehabilitating the internal surface of a pipe by introducing a continuous chemically hardened sleeve.

Our in-house lining crew can carry out lining to drains from 100mm in diameter through to 300mm; we can also line drains with 90 degree bends without creasing the liner.

EPOXY RESIN PATCH REPAIRS

Designed more for a localised repair, fibreglass patches are a cost effective solution to repair a cracked, fractured or damaged drain. This technique essentially involves inflating and bonding an epoxy resin impregnated glass fibre patch to the internal surface of a pipe in order to seal and strengthen damaged areas of drain. Again we are able to patch repair drains from 100mm through to 300mm.

PITCH FIBRE REHABILITATION

In addition, we carry out a pitch fibre drain rehabilitation service that incorporates the technique of pipe bursting and reshaping the host drain then lining in one process.

LATERAL CUTTING / BRANCH RE-OPENING

After lining has been carried it is sometimes necessary to re-open the now sealed off blind lateral connections. This is carried out with a robotic cutter and CCTV camera. Once complete the newly lined drain is now fully functional.
