Hanson supply specialized concretes for Dawlish sea wall

摘要

Hanson have supplied a range of complex concrete mixes to BAM Nuttall to build a new sea wall in Dawlish, Devon. The existing sea defences along this stretch of coast had been eroding to the point of failure, threatening the main railway route to the South West. The new sea wall will protect the line and nearby houses, as well as improving safety for pedestrians. Hanson supplied a total of 6,000m~3 of ready- mixed concrete for the works, which involved pouring concrete foundations on the seafront to house a precast nib section. A separate precast facing panel sits in the nib, tied to the existing wall behind, and the void between the existing wall and the facing panels was then infilled with ready-mixed concrete before a paving concrete was laid on top to create a new, widened pedestrian walkway.
