Drain relining is a cost effective alternative to traditional drain repairs and one major benefit is the lack of mess it creates. At Scanprobe, our non-intrusive, no-dig technology will ensure your drains are back to perfect working condition quickly, and that they remain free flowing.
The drain relining method
A flexible liner impregnated with resin is pushed through the drain while 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 that is in fact stronger than the original.
Drain pipe re-rounding
This is a method of winching a specialist re-rounding tool through the pipe to reform it to its original shape enabling the pipe to be re-lined.¬†Scanprobe 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 repairs
Typically used in areas where traditional excavation is difficult or with awkward access, localised patch repairs are a fast, cost efficient method of repairing blistered pitch fibre or crushed pipework in diameters of 100m to 450m and to a length of usually 100m. Repair work can include re-forming the pipe if necessary and then installing the patch liner.
Water Authority Standards
We will provide an extensive in-depth quotation before undertaking any sewer or drain repair works, which can be shown to insurance companies if required. We use the most modern and current sewer renovation methods to ensure all our work is carried out to Water Authority Standards.¬†One of our engineers will be able to perform a site survey prior to quotation, and will explain the necessary steps required for the repair.
