How about this: “Is your garage floor cracked and sagging in the centre?”

The Causes

When a slab cracks down the centre, it often indicates that the ground beneath has shifted, creating a void underneath. These voids can result from water erosion of the soil or the natural settlement process.

Settlement occurs as the weight of the building compresses the ground. Granular soils, such as those with sand or gravel, are more loosely packed and prone to forming air pockets, which can contribute to settling.

If erosion is the problem, check where your gutters and downspouts discharge water. We advise downspout extensions of at least ten feet. away from your home to minimise erosion and water damage. Need help to extend your downspouts?

The Solution

If there is a space beneath your garage floor, slabjacking is an effective way to lift the concrete back into place. This technique involves injecting polyurethane foam beneath the slab. The foam rises as it thickens and solidifies the concrete to its original position. Once the slab is aligned correctly, you can fill and seal any cracks in the floor.

Is your garage floor sinking or sloping downward?

If the floor tilts to one side, it may indicate that the garage foundation is settling, often accompanied by cracks in the foundation and walls. We evaluate the floor’s alignment with the walls to determine the best repair approach.

Does your garage floor meet the wall or extend across the entire area? In some cases, as shown in the images below, the concrete slab floor also serves as the base of the wall, making it a crucial part of the foundation.

This means that helical piers are the primary solution required. Installing piers can stabilize both the wall and the floor simultaneously. The picture on the right shows a classic stair-step crack on the garage’s exterior, indicating that Pulling away from the remainder of the wall, the front corner has settled. Piers is going to guard this corner and prevent further movement.

If the piers also raise the foundation, we recommend performing slabjacking. Slabjacking fills any voids created by the lift rather than lifting the floor itself. If the floor isn’t lifted, no void will be formed so that slabjacking foam won’t be necessary.

Conversely, if your garage floor stops at the wall and isn’t part of the foundation, it is considered a “floating slab” floor. In this case, repairing your garage will require both piers and slabjacking. Piers will address the foundation issues, while slabjacking will lift the floor once the foundation is stabilized.

Does your garage need foundation repairs?
