Slab Rocking is concrete slabs constructed on unbound sub-bases can cause ‘steps’ at joints, the main cause being movement of the sub-base. As heavy vehicles such as forklifts travel over a joint, the slab on the approach side is deflected downward. When the wheel leaves, it quickly deflects upwards creating a gap of low pressure between the slab and the sub-base drawing minute amounts of material from beneath the departure slab to the other side of the joint.

Concrete Slab Rocking
Concrete slabs constructed on unbound sub-bases can cause ‘steps’ at joints, the main cause being movement of the sub-base. As heavy vehicles such as forklifts travel over a joint, the slab on the approach side is deflected downward. When the wheel leaves, it quickly deflects upwards creating a gap of low pressure between the slab and the sub-base drawing minute amounts of material from beneath the departure slab to the other side of the joint. After many passages from the vehicles, a significant amount of material is moved across the joint, resulting in ‘stepping’, ultimately leading to slab cracking and slab rocking. The edges are pressed against each other causing spauling of the slab and eventual pockets, resulting in “bumps” or “ruts” that slow forklift traffic substantially. Damage and spills are often the outcome.
HMI Polyurethane Foam
Injection of polyurethane concrete lifting foam to stabilize and lift the slab, eliminating “Slab Rock” and can reduce the down time over conventional repairs from days and weeks to just hours. Slab Rocking occurs and can be eliminated in almost all heavy vehicle traffic locations.
Things to Consider When Hiring a Foundation Repair Contractor
Although early signs of foundation damage are easy to spot, finding a reliable company that offers quality foundation repair in Los Angeles can be challenging. Because the city’s consumer protection agencies receive a fair amount of complaints about dishonest providers, it helps to look out for the following qualities in a contractor:
Unfortunately, there are companies that will gladly take your money for unnecessary fixes. All homes settle and adjust, and small cracks may appear on your home’s foundation over time. However, having minor cracks doesn’t mean that repairs are immediately necessary, and contractors are supposed to know this. To avoid unnecessary costs, it helps to find a foundation repair company that offers a free, no-obligation initial inspection. You can also seek a second opinion or do your own research first.
When it comes to fixing home foundations, experience counts. This is why hiring a contractor based on price alone is not a wise strategy. Everyone wants value for money, but your contractor also needs to be able to fix the problem and be around long enough to back whatever warranties come with the services.
Licensed and Insured
Hiring a company that is licensed and insured to provide foundation repair in Los Angeles can mean the difference between quality service and a home improvement nightmare. As a homeowner, it can guarantee your satisfaction and ensure that the contractor meets the minimum qualifications needed to complete the job. Before hiring anyone, be sure to check with your state or city’s licensing board first.
Most companies will offer warranties that will cover you for workmanship and parts, but not all will offer financing, as well as installations that come with a written, transferable 25-year foundation repair warranty.

You’re seeing signs of foundation damage on your property. It’s typical for panic to set when thinking about the potential safety risk to your family along with the extensive process of repair.

The most common causes for concrete slab settlement can be attributed to drying and shrinking soil beneath a slab, poorly compacted fill soils, or a washout of soil. All of which will create a void below the slab. If the concrete is not strong enough to span the void, the slab will eventually crack and break. This type of damage can be a major problem and can cause serious destruction to a home or building.
Concrete settlement is caused by changes in the moisture content and density of the soils beneath a concrete slab. Whether it be poorly compacted fill soils, or erosion, these changes create voids beneath the slab which eventually cause the concrete to crack, break and settle.
When foundation settlement problems occur, it’s typically caused by changing soil conditions beneath and around your home. Soils that dry and shrink, become wet and soften, or poorly compacted fill-soils can result in your home to shifting, sinking and settling down into the earth. If you notice one or more of the below signs…
There is a common misconception that the cause of foundation settlement is due to the design (or under-design) of the structure itself. Instead, the real culprit of damage can be attributed to changes in soils beneath and surrounding the foundation and structure. Here is a list of the most common changes that occur in soil which cause foundation settlement.
Surprisingly, foundation settlement problems are very common. Why? Well, mainly because buildings are heavy and many types of soils beneath their foundations have poor load-bearing capability.
