Structural Wall Repair

Repair. Rebuild. Restore.

Structural damage can occur for many different reasons. Some of the more common repairs we do are listed below.

Bowed wall – Block foundation

Bowed Foundation Wall Repair

The bowed foundation wall misfortune arises due to frost and/or frost susceptible material, usually clay soil. The clay adheres to the block wall and with the frost expansion the mortar bond is broken. Now the lateral load of the soil on the wall can force the wall inwards. It happens most often along the side of a house where there is a laneway.

Depending on the severity of the bow, we can strengthen the wall and stop the bowing without replacement of the wall. We use carbon fiber and epoxy for this type of repair.

Underpinning – Stone wall


Underpinning may be required when it is determined that the soil material under a footing is not suitable to hold the load for the structure it’s required to support. If suitable soil is found within a few feet lower, we can excavate, form and fill the void with concrete. All under Engineer’s supervision and approval. Permit Required.

Frost Heave Repair

(usually on Garage Foundations)

One weather condition that can adversely affect the foundation of your home is frost heave. This condition consists of ice/frost forming underneath in the soil. As the soil beneath and/or against your foundation alternates between freezing and thawing, shifting occurs, which can lead to structural damage in your foundation. Other frost related issues that are quite common are: frost heaving on garage walls. This happen on garage walls because the frost susceptible material is on both the inside and outside of the walls. The material sticks to the concrete wall and lifts the foundation. Usually causing a long horizontal crack. The frost susceptible material can also expand from the inside of the garage pushing the wall(s) outward.


Settling can occur when the bearing capacity is not sufficient for the weight being placed on it. This type of settling occurs very soon after construction and can last for many years until it is complete. It can start again with added weight. Like adding a second floor or material against the walls.

Trees are a common cause of settling. This happens when a tree matures, and the root system starts to draw moisture from the clay soil under footing of you foundation. This causes desiccation of clay, and the footing then drops.
