Why Choose AllenCo Constructions for Structural Underpinning?

Your home is likely one the biggest investments you have, make sure it’s sitting on a solid foundation to ensure it retains and grows in value in years to come.

Cracked walls, uneven floors and doors that no longer align to their frames are all signs that the foundation of a house may have sagged due to unstable soil beneath the structure.

Underpinning concrete footings is a means of 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.

AllenCo 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 up, 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 is 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.


Underpinning the foundations of your precious home can solve your wall cracking problems, repair structural damage and safeguard your investment.
