CFA piles and Sheet Piling installed in Newark to facilitate the replacement of a tunnel with a 1.5-metre diameter one.
Sheet Piling and Continuous Flight Auger (CFA) to sewer scheme in Newark, Nottinghamshire, UK. Leading UK foundations and sheet piling contractor Aarsleff Ground Engineering has completed the CFA and Sheet piling works for a major new scheme that will protect homes in Newark from sewer flooding and provide a reliable water supply for decades to come. In 2016, Nick Wallace from Severn Trent explained that £60 million would be spent to replace more than 12 miles of old piles with new, larger ones.
Aarsleff worked on Queens Road to facilitate the replacement of a tunnel with a 1.5-metre diameter one. We employed an ABI TM13 /16SL with a Hydropress to pre-auger, and further installed 28no PU22- 12m long sheet piles. Due to being in a residential and restricted area, Aarsleff employed a Silent Hydropress to drive in the sheet piles to reduce the vibration.Download Case Study
