Garage Floor Concrete Levelling

Concrete Levelling Garage Floors

Whether it is a detached or an attached garage, you can experience a sinking floor. People often notice their garage slab has sunk when they see a gap under the overhead door. Another sign could be if the water in the eave troughs is not running down the drainpipes but is spilling over the edge or if water from a vehicle is pooling in only one area. Nevertheless, once noticed, a sinking garage floor should be raised as soon as possible.  


When it comes to detached garages, the damage normally occurs to the wood portion if the floor has sunk to the wood structure’s outer edge. Only recently have garage floor plates been manufactured from treated lumber to avoid rotting. The problems with attached garages, however, are different.

In the case of an attached garage, as a result of poor compaction during backfill, floors often sink at the foundation wall. This causes water from vehicles to spill towards the foundation. In general, floor slabs are dowelled into the foundation, and this water causes these metal dowels to rust. As a result, these dowels will eventually fail and cause cracking. This makes raising the slab far more difficult for several reasons. First off, the concrete will jamb into the foundation and become so locked that the floor’s outer edge may need to be cut to raise the floor, adding extra costs. Another issue is that the cracks will fill with debris, the weight of the vehicles will further pack the debris into these cracks, and it will become impossible to close the cracks. Finally, water that runs down the side of the slope will only further sink the floor.

All and all, as made clear in the reasons above, it is always best to address the issue of a sinking floor as soon as possible. Call Ground Level Solutions for a consultation and free estimate.
