Monday, July 18th, 2016 by Jaimie Hooker

Being a homeowner comes with much responsibility. If you have a sinking slab, hosting a party or cookout could be a major liability and safety hazard for your guests. Once a slab is cracked and sinking, it simply won’t get better with time. In fact, it only gets worse.

Concrete pool decks, patios, and porches can all sink and settle for different reasons, it’s important to understand why your home is suffering from slab settlement.

There are three common reasons for slab settlement:

There are three common reasons for slab settlement

1.) Changes in the soils moisture content

The most common soil type for the Tar Heel Basement Systems service area is clay. When clay becomes wet, it holds onto the water and expands in size. When it is dry, it shrinks.

The result? Cracked and unlevel concrete.


As water moves beneath your concrete slab, it can wash away the soil that's supporting the weight of the concrete2.) Wash-out of soil under the slab

As water moves beneath your concrete slab, it can wash away the soil that’s supporting the weight of the concrete. This can be caused by plumbing leaks, erosion, and large rains.


3.) Poorly compacted fill soil

Poorly compacted fill soil leads to slab settlement

During construction of the pool deck, patio or concrete porch soil is commonly moved around or spread out to get the desired grade level. Oftentimes, the concrete slab is poured directly on top of the fill soils that have been moved around. If the soil was poorly compacted, the fill soil compresses and settles, and a void is created under the slab.

Don’t let your sinking pool deck, patio or porch become your family’s main worry this summer. Tar Heel Basement Systems can correct and prevent your sinking slab from ruining your summer fun! Call our office to schedule a free evaluation.
