The contract required immediate response to a relief programme, developed to respond to unprecedented flooding of the Somerset levels, as widely publicised in the international news media. Hundreds of homes and many farms in the surrounding villages were overwhelmed with floodwater and overflowing foul water, following a series of heavy storms over a number of weeks.
Extensive flooding in recent years has started to erode the footings of some of Network Rail’s river bridges.
The contract required TMS Maritime to repair a bulging, misaligned existing random stone and sheet pile sea wall, which had been breached during heavy storms in early 2014 and was in danger of collapsing.
Extensive flooding in recent years had eroded the foundations of the level crossing and the river bank, supporting the main line rail track running only 8 metres from the water’s edge. Scour protection and a new river bank of rock armour was needed, to prevent further track movement and level crossing subsidence.
Salmon’s Brook has been associated in the past with significant flooding both historically and more recently back in October 2000.
In recent years, scour has resulted in the river bank failing, with bank material falling into the river and this therefore required remediation.
As part of Somerset’s flood defences, TMS were called in to replace a failing outfall head wall along the bank of the estuary at Tuckett’s Clyce in Somerset.
