Drain Relining And Drain Pipe Re-rounding Service


Posted on: January 14th, 2014

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.

 

Drain relining benefits include:

  • No-dig or excavation of surfaces
  • Minimum disruption and down time
  • Suitable for drain/ pipe diameter ranges 100 to 1200mm
  • Suitable for handling bends and offset joints
    • Increased flow rates
  • Various types of pipe material can be renovated
    • Tree root infestation prevention
  • Lining systems available for runs containing diameter changes
  • Runs of up to 100 metres relined in one continuous length
  • Renovation and reline works are covered by our Company guarantee

Inversion Drain Lining Using No Dig Technology


Posted on: December 30th, 2013

Repairing drain lining using No Dig Technology is a proven and established method of inserting a new replacement pipe within an existing damaged pipe without needing to excavate.

The new drain lining is inserted into the damaged pipe by a method called inversion which uses either water or air pressure to fit it tightly within the wall of the existing damaged pipe. When the inversion process is complete the new pipe structure is completely rigid, producing a stronger, reinforced pipe fitted within the existing pipe resulting in a minimal loss of diameter of approximately 6%.

The drain liner is manufactured from a special dense impermeable felt and is designed and tailored to fit exactly the internal dimension of the pipe to be refubished. The thickness of the lining material can be varied according to design specifications required. We recommend the following products:

 

Drain Lining - Renoline Flexiliner

  • For use in any inversion machine, and can also be dragged-in

 

  • For use in bends up to 65° (inversion) or 90° (Drag-in)

 

  • Low Friction

 

  • Double heat-welded seam for added strength

 

  • For air-tight and water-tight applications

 

  • Fast resin absorption
