Causes & Repair Solutions For Cracked, Sinking Concrete Floors

slab-piers-thm

Concrete slab piers being used underneath a floor to help stabilize the floor permanently.

Notice how the piers can extend deep below the floor, extending until they reach competent supporting soils.

The Problem:

Your concrete slab floor is showing signs of sinking, sagging, or settling. Your floor may be cracking, or the walls may be separating from the floor below or ceiling above.

Telltale Signs:

  • Cracks in the concrete floor
  • Floors dropping and separating from the walls, forming a gap between the floor and wall.
  • Interior walls separating from the ceiling, forming a gap between the wall and ceiling.
  • Walls pulling away from adjacent walls
  • Interior wall cracks, commonly off the corners of interior doors.

How to Fix It:

Install a slab pier system underneath your concrete slab floor. These piers can extend down to strong supporting soils, ensuring long-term support.

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:

Shrinking Soil

Drying/Shrinking Of Soils Under The Slab

Soil Washout

Washout Of Soil Underneath The Slab

Dirt

Poor Compaction Of Foundation Fill Soils

Installing The Supportworks Slab Pier System

Supportworks Slab Pier System stabilizes the concrete floor slab in your home. It provides the best opportunity to relevel the floor and lift non-load bearing partition walls that may have settled along with the slab. To install our system, our contractor will take these six steps:

What NOT To Do

As with most home repairs, some work all of the time, some work some of the time, and some don't work at all. Here are two fixes that we at MidAmerica Basement Systems do NOT recommend:

Jackhammer

Concrete Slab Replacement:

To perform a job like this, all home furnishings, floor coverings, and interior walls must be removed. Then a crew jackhammers the existing floor into small pieces and removes them by hand.

Once this is complete, a new floor is poured and the homeowner must allow two weeks for the grout to cure sufficiently.

The interior partition may be rebuilt, floor coverings may be reinstalled, and home furnishings may be returned.

While this situation is disruptive and expensive, the real problem here is that the issue that caused the problem in the first place has not been addressed. Without addressing the soil problems that lead to the floor cracks, your new floor may break over time too!

Releveling

Releveling Grout On Top Of The Slab:

To begin this process, all floor coverings that were placed on the slab must be removed. The floor is then prepared so that grout will be able to bond with the slab surface.

A self-leveling grout is poured along the slab surface, where it begins to fill in the low portion of the floor and create a level surface. After the grout is allowed to cure for several days, the floor coverings can be replaced.

However, if the floor wasn't prepared properly, the grout may not bond well to the surface of the slab, leading to chunks of it breaking off. Additionally, the grout will add weight to the slab, potentially making the situation worse by causing further settlement. And, just like with the last two options, the real problem of soil settlement is not addressed!
