Channel alongside major trunk route in Merthyr Tydfil, South Wales, remediated using Concrete Canvas

07 March 2018

In March 2017, Concrete Canvas® GCCM* (CC) was used to remediate a channel which runs alongside the A4060 in Dowlais, Merthyr Tydfil in South Wales.

The A4060 links the A470 Pentrebach roundabout and Dowlais areas of Merthyr Tydfil. Running adjacent to the A4060 lies a large drainage channel, approximately 410m in length with a variable profile of between 5.5 – 10 linear metres, which takes surface run-off from the hillside, protecting the A4060 from flooding and undermining.

The original earth channel has been remediated using several different methods over the years, including a concrete poured invert, cement filled sandbags to stabilise the batters, concrete slab-work and lean mix grout pours. The dilapidated channel was in disrepair, with significant vegetation growth, collapse and signs of scouring. This would eventually have led to undermining of the embankment on the near side of the A4060.

The works were carried out by ALD Plant Hire, CEMEX’s Civils Engineering partner, for SWTRA (South Wales Trunk Route Agent), with design specifications provided by AECOM.
