Ground investigation work for the next phase of coastal protection work at Borth in west Wales has been successfully completed by Lankelma.
Working between tides, Lankelma carried out cone penetration testing to 25m below ground level to investigate the nearshore geology for Ceredigion County Council under supervision of Royal Haskoning DHV.
The information will be used to design new coastal defences to replace the existing ones that were constructed in the 1960s and 1970s, which have suffered from overtopping leading to coastal erosion and flooding in the village of Borth.
The CPT work was designed to characterise the deformation of the highly compressible soft clays which underlay the area. Lankelma also undertook 24 excess pore pressure dissipation tests were undertaken during four inter-tidal day shifts to acquire data and derive the in-situ measured coefficient of consolidation.
