Dam Protection in Llyn Bodlyn, Wales

A Reno Mattress Solution in an Area of Natural Beauty

Llyn Bodlyn reservoir is situated above the village of Tal-Y-Bont, near Barmouth in Gwynedd, Wales, it’s an absolutely beautiful sight to behold for Maccaferri Engineer Alex Jones.  As the winter season approaches so does the risk of higher water levels and increased wave action, leaving the dam wall vulnerable to water breaches.

A technical solution was needed to prevent the erosion of materials directly below the downstream side of the dam wall in the event of a water breach.  Mott MacDonald Bentley (MMB) has been commissioned by Dwr Cymru (Welsh Water) to carry out remedial works and a rockfill berm was the favoured option.

The 6m wide berm will span approximately 80m at approximately 1.5m in height.  The reno mattresses which will be placed on top and on the slopes of the berm are designed to withstand the scour impact of water breaching the dam wall.

A successful install and happy clients at J N Bentley.
