Laycock Centre


Value: £130,000
Size: 167m2
Duration: 10 weeks
Rig: Klemm 702

Scope of work:

  • Abbey Pynford were approached by the local authority to underpin the corner of a building which suffered from severe ground movement.
  • A piled cantilevered scheme was proposed to avoid extensive internal works and to accommodate the extreme depth (5m+) of desiccation in the clay based subsoil. The scheme was designed by our in house design team and comprised of 300mm diameter SFA piles installed to a depth of 19m, with a Klemm 702. We used temporary casings to the top 4m to overcome the made ground and seal into interface with the London Clay below.
  • The piles and ground beams were carefully configured to ensure that the scheme did not conflict with the extensive services and the existing structure.
  • The 600mm2 reinforced concrete ground beams were installed on 110mm clayboard to provide a heave void beneath. The existing walls were supported on Pynford Stools to allow the masonry to be removed and the beams / antiheave precautions to be installed above the existing foundation. A continuous beam was formed within the existing wall to span between the ends of the cantilevered ground beams.
