What is Underpinning and how do I know if my home needs it?

Underpinning concrete footings is a means of foundation repair by propping up and strengthening the foundation so the structural damage of the home or property is repaired, and further damage and unsightly signs of a poor foundation are avoided.

You may require underpinning if you notice the following:

  • Cracked walls
  • Uneven floors
  • Doors that no longer align to their frames
  • Windows that are hard to open
  • Persistently damp ground
  • Dry, cracked soil
  • Sagging or sloping floors or ceilings

allenCO construction structural underpinning involves excavating the original footings, then pouring more concrete underneath the footings and reinforcing it with steel to give additional strength and stability.

Once the concrete has cured (this typically takes around five days depending on damage and weather conditions) – heavy-duty jacks are placed on the reinforced concrete and the whole structure is jacked up, this closes up those cracks and voids.

Once the cracks have been successfully closed, either heavy-duty props are positioned to stop the building from sagging again, or the jacks are left in place and more concrete and steel reinforcement are used to make the repairs permanent and strong. The job is finished once we are convinced the foundation is as strong as it can be.
