Rhondda Cynon Taf Council will begin a six-week programme of work on Allen Street in Mountain Ash starting Monday, 16 November. The project focuses on repairing and strengthening river walls and embankments along the Nant Ffrwd watercourse, which runs through a residential area.

The council said the scheme is designed to improve the resilience of existing infrastructure during storms. Planned work includes temporary repairs to areas affected by scour and undercutting, vegetation clearance, repointing of masonry river walls, and rebuilding a leaning headwall.

Edwards Diving Services has been appointed as the contractor. The work is funded through the council’s Highways and Engineering capital programme (2026/27).

For contractors working in similar settings, this job is a reminder that masonry maintenance is not limited to buildings. River walls and headwalls rely on sound mortar joints and stable geometry to hold line under pressure from moving water. The council expects local traffic management with barriers and some carriageway incursion, with no road closures anticipated. Some footway sections are set for closure, with diversion routes maintained where possible, while access to nearby premises is expected to remain unaffected.
