Flood Defence and Prevention Expo

Mostyn Sea WallWrekin Products, a leading supplier of geosynthetics for environmental protection, erosion control, ground reinforcement, stabilisation, drainage and grass protection will be exhibiting at the inaugural Flood Defence and Prevention Expo at ExCeL, London on 4 and 5 December. Wrekin’s technical team will be on stand no F554 to demonstrate their latest products and offer specification advice.

Wrekin Products geotextile products played an integral role in rebuilding damage caused to sea defences during last winter’s extreme storms. Working with engineers and contractors to provide practical ways to repair sea walls and embankments against a harsh and challenging environment .

At Mostyn in Flintshire storms breached approximately 200m of the sea wall in 6 separate locations, closing the Chester to Rhyl railway line along the sea front.

Working around the clock, Network Rail engineers faced the huge task of removing around 1,000 tonnes of fallen sea wall from the railway and completing emergency repairs to the wall and track before the next high tide. Wrekin Products’ technical team worked with the engineers and Alun Griffiths (Contractors) Ltd to devise a highly effective solution using sand bags wrapped in polythene, Wrekin Multitrack SNW non-woven geotextile and tonnes of rock armour. Over 10,000m2 of Multitrack SNW80 was placed beneath the rock armour acting as a heavy duty filtration and separation layer.

Multitrack SNW was also chosen for Network Rail repair work to the embankment at Old Colwyn, Conwy. Completing the works in just 5 weeks the 100 year old sea defence is now fit to withstand the rigours of constant wave attack from the Irish Sea storms, protecting the an important arterial railway line.

Multitrack SNW is one of Wrekin Products’ range of specialist and general geotextiles and geogrids. SNW non-woven geotextiles offer excellent puncture resistance properties combined with high permeability making then ideally suited for protection, separation and filtration.
