Mostyn Sea Wall Repairs

Mostyn Sea Wall Repairs

  • Network Rail Wales

  • Mostyn, Flintshire

  • 10,000m MultiTrack

When gale force winds combined with high tides on Thursday 5th December 2013, the result was the worst storm surge to hit North Wales in years.

At Mostyn in Flintshire, where the Chester to Rhyl railway line runs along the sea front, the result was approximately 200m of the sea wall being breached in 6 separate locations, forcing the closure of the railway.

Network Rail engineers along with Alun Griffiths (Contractors) Ltd immediately started working around the clock using three heavy excavators to undertake the huge task of removing around 1,000 tonnes of the fallen sea wall from the railway. They replaced 150 tonnes of ballast, then repaired the track, signalling and other electrical equipment to allow the railway line to re-open.

This was achieved in the early hours of Tuesday 10th December when the focus moved to undertaking emergency repair work to the breaches in the sea wall before the next high tide on 2nd January 2014.

To ensure the sea wall repairs were completed as soon as possible, work continued around the clock and in between the high tides.

The storm surge has caused significant damage to the railway in North Wales. We are doing everything we can to get passengers on the move again, but the scale of the work needed means it is likely to be several days before train services resume through the affected areas.

A solution devised jointly by Atkins, Alun Griffiths (Contractors) Limited and Wrekin Products was agreed. This consisted of sand bags wrapped in polythene, Wrekin MultiTrack™ SNW80 non woven geotextile and 2-4 tonne rock armour. The rock armour was placed to fill the breaches in the wall with the MultiTrack™ SNW80 beneath the rock thus forming a key part of the solution by acting as a heavy duty filter/separator.

Thetford Woodland Lodges

Thetford Forest is the UK’s largest man made lowland forest. It’s patchwork of pines, heathland and broadleaves provide the ideal setting for a great day out, and a welcome refuge for a rich variety of animal and plant life. Due to the weight involved, it was clear that the correct selection of ProtectaWeb™ depth was imperative to the success of the project.
