Why Home Inspectors Must Pay Attention to Slab on Grade Concrete Foundations
Updated: Dec 31, 2022
When it comes to inspecting homes, slab-on-grade concrete foundations are a common type of construction and require extra attention from home inspectors.
The slab-on-grade foundation is an efficient, low-cost option for residential structures and can save builders both time and money.
But a slab-on-grade foundation isn’t without its risks, and home inspectors need to be aware of the common structural issues and problems associated with this type of foundation.
In this blog, we’ll provide an overview of slab-on-grade concrete foundations, discuss why it’s important for home inspectors to inspect slab-on-grade concrete foundations, provide an insight into what they should be looking for, and discuss the common signs of structural issues.
What is a Slab on Grade Concrete Foundation?
A slab-on-grade concrete foundation is a solid concrete slab poured directly onto the ground or existing soil and is typically used to provide a base for commercial or residential buildings. It is the most common foundation type used in residential construction due to its cost-effectiveness and ease of installation.
The slab is usually about 4 inches thick and designed with rebar reinforcements to ensure structural stability. This type of foundation has a high load-bearing capacity and is often used in areas prone to heavy flooding or other destructive conditions.
Why Inspectors Must Pay Attention to Concrete Foundations
It is important for home inspectors to inspect slabs on grade concrete foundations because they are susceptible to settling and cracking due to drying shrinkage, foundation movement, or inadequate reinforcement.
These issues can lead to costly repairs for homeowners if not caught early by an experienced home inspector. Slabs on grade foundations should be properly evaluated for signs of settlement, cracking, and heaving.
The inspection should also include an assessment of the drainage around the foundation, which is essential for the long-term health of the slab.

What Home Inspectors Look for with Slab Foundations
1. Cracks – Inspectors should look for any vertical or horizontal cracks in the concrete foundation. These may be indicative of a structural defect or shifting of the structure of the foundation.
2. Dampness – Home inspectors should look for any evidence of moisture, such as water damage, staining, or mold. The presence of dampness on or around a concrete foundation can indicate a critical problem.
3. Movement – Home inspectors should check the foundation for signs of settling or shifting, as this could indicate that there is an underlying problem with the foundation.
4. Leaks – Home inspectors should check for any evidence of plumbing or roofing leaks. Leaks can cause damage to a concrete foundation and should be rectified as soon as possible.
5. Deformation – Home inspectors should check for any deformations or unusual bulging or bowing. This could indicate that the foundation is beginning to fail.
6. Root intrusion from plants, and trees may uplift the foundation and cause unsettling.
