Underpinning

What is Underpinning?

Underpinning  is remedial repair work for structural problems associated with foundation movement.

It is a systematic process where extra concrete is placed under the existing footing on new appropriate foundings.

It is the only sure fix when a building shows signs of movement or stress associated with foundation settlement.

When might I need underpinning?

  • Your floors are out of level.
  • Door and windows are not closing.
  • There are cracks in the plaster.
  • You have cracking in your brickwork.

What are the causes of the damage?

  • Shrinking of subsurface clays.
  • Inadequate founding of footings.
  • Large tree roots impeding under your foundations.
  • Drainage or water issues.
  • Drought or flood causing extremely dry or wet soil.
  • Substandard building practices.

What is the repair procedure?

  • Assessment of building including reasons for distress.
  • Design and document a systematic remedial repair including placement of underpins and associated works.
  • Organize plans and paperwork for permits as required.
  • Removal of landscape units as needed.
  • Excavate to suitable founding.
  • Building surveyor inspection and confirmation.
  • Pouring of new concrete.
  • Lift and grout off building of new underpin foundation til original position or as close as possible.
  • Tidy-up brickwork or superficial repairs as needed.
  • Re-instate landscape to original condition.
