Wilkinson Environmental Ltd's patch repair system is designed to achieve a point repair without the need to reline the full length of a sewer.

A fibreglass matting is impregnated with an epoxy resin, which is then secured around an inflatable flow-through packer and allows the sewer to continue operating without the need for over-pumping. The packer is pulled into place and inflated to cover the defective area. A choice of 600mm and 1000mm patches can be used to repair defects.

This method offers a cheap and efficient system of repair and can be installed in pipe work from 100mm to 900mm.

Suitable applications for epoxy patch repairs:

• Spot repairs on foul and storm drainage systems, including all private, S24 and main sewers
• Prevent root growth on single joints after root cutting
• Sealing leaking joints, preventing infiltration and ex-filtration of sewers
• Repair damaged sections of sewer lines bringing a grade 5 sewer back to grade 1
• To cap off redundant or root filled connections and junctions
• To repair defects within diameter changes
