Project: A4233 Maerdy Mountain Road
Owner: Rhomdda Cynon Taff Council
Designer: Tony Gee & Partners LLP
Contractor: Alun Griffiths
Purpose: To create a weight-retaining wall spread along the toe of a re-profiled slope for landslip stabilisation adjacent to the road and offer protection against further landslides.
RamWall type: 8m diameter 200mm x 200mm galvanised RamWall mesh plus 5mm diameter, 50mm x 50mm galvanised facing mesh, 25 mm rebar spikes.
RamWall Fill: The RamWall consisted of a graded granular fill.
Date: August, 2017.
The vital project at Maerdy Mountain Road was undertaken following a landslip caused by prolonged rainfall in December 2015, which had resulted in the damage of a 150-metre stretch of the road. Taking advantage of a necessary full road closure, wider improvements to future-proof the route were undertaken thanks to significant Council investment through #RCTinvest. RAMWALL was selected by the designer to stabilise the toe of the re-profiled slope immediately alongside the road. The RAMWALL is mostly 1-metre in height, which increases to 1.5-metres over a 30-metre stretch of the slope. It is filled with graded granular rock fill and backed by a waterproof membrane, provided with a back of wall catch drain at the bottom of the slope constructed using concrete canvas.
The chosen materials and techniques ensured long-term stability and durability, addressing both structural and environmental considerations. On-site training for the contractor’s personnel was happily and readily provided by ISS, who also worked closely with the designer to produce an efficient, cost-effective, and visually sympathetic design for this sensitive landscape in the Brecon Beacons of South Wales. The work was completed to time and budget with only minimal disruption to local traffic flow and access.
