DALROD – Drain relining

DALROD sewer renovation and drain relining lorry and engineers

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.

The drain relining method

A flexible liner impregnated with resin is pushed through the drain, whilst an air bag is also pushed through to mould the resin to the pipe. The liner is heated, and once cooled will mould exactly to the sides of the original pipe. Once the air bag is removed, it leaves behind a smooth new pipe inside the original.

DALROD have recently introduced the Browliner® environmentally friendly re-lining system for working on sensitive projects and in the majority of situations would use epoxy resin EP09 100-1 conforming to BSEN13566-4:2022 which is the only resin to attract WRC approved PT/313/1010.

Full drain relining benefits include:
  • No excavation of surfaces
  • Less disruption and down time
  • Suitable for diameter ranges 100 to 1200mm

  • Runs of of up to 550 to 600 metres relined in one continuous length

  • All renovation and reline works are covered by our 25 Year Guarantee
DALROD flexible reliner is pushed into the drain

A flexible liner impregnated with resin is pushed or pulled into the drain. Once in place, an air bag is blown through and inflated to shape the liner to the size of the drain.

Drain pipe re-rounding service

DALROD offer a pipe re-rounding service to pitch fibre drains together with hydraulic pipe bursting and directional drilling. A lead bullet is pulled through the collapsed drain which re-opens the pipe allowing the liner to be put in place. When the liner has cured, the result is a drain once again in perfect working order.

Localised patch repair service

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.

Water Authority Standards

We provide an extensive in-depth quotation before undertaking any sewer or drain repair works, which can be shown to insurance companies if necessary. Furthermore, we use the most modern and up-to-date sewer renovation methods to ensure all works are carried out to Water Authority Standards.

One of our engineers will be able to come out and assess the situation prior to quotation, and will thoroughly explain the action plan required to get your drains running smoothly again.
