Project: Fisher Street Wallsend
Works: Underpinning using micro piles.
Equipment used: Klemm 500 mini rig
C&J Geotechnical Services carried out the design and installation works to underpin the corner of a building which had begun to sink at one corner. The Micro piling works consisted of a self-drilling system using a hollow fully threaded 38mm diameter drill rod with a 150mm diameter sacrificial drill bit , both the drill rod and the bit are left in situ to form the cement grouted micro pile. The piles were drilled through stiff clays to a depth of 9.0mtrs using our powerful but very small Klemm 500 drill rig. 54 piles were installed in a two week period , on time and budget.
