Monmouthshire & Brecon Canal : Relining Project

Client:

CPC Civils

Employer:

Canal & River Trust

Location:

Llangattock, Powys

Contract Size:

Supply and installation of 8,000m² 1.20mm Landflex PVC120AP

Summary:

Supply and installation of 8,000m2 PVC120AP 1.2mm geomembrane linings sealed to Fosroc water bar (as shown below), with protection geotextile and additional in-situ welding at two bridges.

• Highly robust & resilient materials required due to waterways traffic.
• Recommended materials must be approved by the Canal & River Trust.
• PVC120AP has been successfully installed in other canal relining projects in previous years.

Our PVC120AP geomembrane with liner protection 8000CBR geotextile above and below was recommended due to its durability and suitability for applications of this nature. The materials have a proven track record following successful completion of other canal lining projects in the area in previous years.

Challenges:

The lining system had to be installed within a rigid time frame due to other planned works and contractual requirements, and in order to minimise environmental impact to the surrounding area and wildlife.

The initial project was completed on time including sealing to the Fosroc
water bar where required and the mechanical fixings to bridges 115 and 116 and the head walls, and was successfully passed back to the client for the concrete to be poured. Once the concrete was poured it became apparent that while the
water edging installed and lined was entirely to spec, there was a requirement for additional material to be welded to the edging.

Our Solution:

The canal section had already been refilled , meaning that the additional material welding operation had to be completed from a boat on the water. Our approach to this final challenge was deemed outstanding by the client, CPC Civils, who were very grateful for our initiative in providing a resolute solution.

Contract Period:

7 Weeks
