Signs of slab settlement

When a floor slab settles, the damage can manifest itself in many ways. Along with cracks in the concrete, the floors can separate from the walls as they sink downwards. Alternatively, the interior wall may be pulled down with the floor, instead of separating from the ceiling. Walls can also pull away from other walls, and interior wall cracks can form -- commonly off the corners of interior doors.

What causes a concrete floor slab to settle?

When a concrete floor settles, it can mean serious damage to your home. The causes of floor slab settlement are almost always due to the soils underneath being unable to support the weight of the concrete. They often accompany other foundation problems in your home.

The three most common causes of settling concrete floor slabs are as follows:

Drying & Shrinking of the Soil Under the Slab

HVAC (Heating, Venting, and Air Conditioning) systems may be installed beneath the floor slab. Over time, the ductwork can leak air, which can dry out the soil.

As the soil dries and shrinks, gaps form under the floor slab, creating voids. Because the soil no longer supports the floor slab, the floor begins to crack and sink into the voids.

Washout of Soil Under the Slab

This is usually caused by plumbing leaks. If the plumbing leak is severe and there is a path for the water to flow through, it can wash soil out from under the slab.

With a void underneath the floor, there's nothing supporting the concrete slab anymore. In time, it begins to crack and sink downwards.

Poor Compaction of Fill Soil

During construction of a new home, layers of soil are commonly moved around or spread out to get to the desired grade level. When the home is built, footings may be deepened to extend below weak fill soils and avoid a foundation settlement issue.

The slab, however, remains on the fill soils. If the fill was poorly compacted, the fill soil compresses and settles, and a void is formed under the slab. In time, the slab cracks, breaks, and settles into the void.
