Cat & I Concrete Cutting & Demolition is an expert concrete foundation contractor for residential and commercial properties.

A cracked concrete slab foundation can invite unwanted structural problems that a homeowner or business owner may not notice until too late. For example, an excess of moisture can seep into the cracks and weaken the concrete over time. Eventually, this causes the concrete foundation to collapse along with the building on top of it.

That is why it is essential to pour concrete slab foundations correctly the first time, and why this job should only be trusted to trained concrete foundation contractors.

The Importance of a Well-Planned Concrete Foundation

At Cat & I, we prepare the ground so that your concrete slab foundation will be efficient.

A reliable concrete foundation is the most important base of any effectively built structure. It is the first fabricated part of a construction project, setting a precedent for the overall success of the building.

A poorly laid concrete foundation will cause building problems that lead to additional structural conditions later, like sinking.

Professional concrete foundation contractors recognize that properly poured concrete slab foundations can last a lifetime but need to be planned and executed with extreme preparation. This means that soil conditions, backfill, water tables, and overall design must be thoroughly considered before the concrete slab foundation is poured.

A professionally executed concrete slab foundation can prevent costly repairs in the future.

3 Signs a Concrete Foundation Is Defective

Some of the structural problems a defective concrete foundation can create are:

Foundation Upheaval

When a concrete foundation starts to curl up or down or appears uneven, it’s referred to as upheaval. Upheaval means that the foundation is moving upward.

Signs of upheaval include cracked walls, raised or cracking floors, and sticking doors, among other indications.

Foundation cracks allow insects and moisture to enter the building and cause unseen mold to grow. Mold can cause respiratory issues as it circulates throughout a building and aggravates health issues.


A certain amount of settling is to be expected as a concrete foundation sinks into the ground. Extreme, unwanted settling can cause uneven floors, separation around walls or garage doors, displaced moldings, and a cracked foundation.


Gaps in the concrete can be caused by not matching the temperature of the wet concrete with the outdoor temperature when a contractor pours a concrete slab foundation. Gaps can also occur when the concrete poured is not thick enough, when the mix is not right, and when the rebar is not spaced correctly in the foundation.

Gaps in a concrete foundation can cause cracks, splintering, and general weakening of the concrete.

Advantages of Concrete Foundations

Expert concrete foundation contractors understand the dangers of pouring concrete slab foundations haphazardly. However, a concrete slab foundation has advantages over other types of foundations such as:

  • Resistance – properly installed concrete foundations can resist underground water, insect infestation, mold, and rot
  • Maintenance – there is no crawlspace or basement to maintain, and solid concrete requires almost no maintenance
  • Strength – this is especially noticeable for commercial buildings that test foundations with the weight of large buildings
