Aarsleff Piling has installed what are thought to be the longest mass produced precast concrete piles ever driven in a single piece in the UK. The 17m long, 250mm square section piles were manufactured at the company's precast concrete pile factory in Newark, Nottinghamshire and driven by one of the company's Banut rigs. Work was for a new housing scheme on St Mary's Island in Chatham, Kent for developer Countryside Residential (South Thames)
Aarsleff says that key to the pile's development, is its computerised reinforcement cage fabrication and welding robot. This can rapidly make extremely rigid, high quality cages with very strong spot welded joints at every steel to steel interface, unlike flexible handmade cages which rely on wire wrapped joints.
