I'd like to share a case study from a recent job that I consulted on with one of our contractor customers, ETRU Spray Foam and Coatings and Coatings in Southern Illinois.

A 25’ x 40’ residential pole barn in Carbondale, Illinois was built on a 6” floating concrete slab on grade. The concrete was poured into four 10’x 25’ sections. Each section had multiple cracks and breaks throughout, and in some cases, the broken sections had a drop of up to 3”. During the inspection, it was discovered that the pole barn 4 corner beams were driven into the ground and the concrete poured around them. The front of the property was pitched towards the pole barn and it showed no signs of ever having gutters and downspouts attached. After drilling an injection hole, we inserted a probe to check the depth of the void and the stability of the ground. In some areas the void was 6” and the probe was hand driven to a depth of 3’ before hitting hard ground. ETRU Spray Foam and Coatings was hired to stabilize the ground and level as much of the concrete as they could. The homeowner plans to utilize the space as a game room.

Powerful Polymer

Among the most dependable products for geotech applications, AP Lift 430 structural foam provides an exceptional DOT grade solution for these types of situations. This 3 lb. density, high-strength, hydro-insensitive structural polyurethane foam is perfect for densifying soil and lifting concrete slabs.

Painless Procedure

The ETru crew and I walked the project with both property owners. We pointed out how waterlogged the ground was and that they needed to add gutters and downspouts, as well as pitch the ground water away from the pole barn. We also talked about possible blowout from under the slab during the injection process and how to handle it. I worked with ETRU to draw up a plan, indicating exactly where the injection points would be located (knowing that the plan might change due to the ground moisture and the number of voids to be filled). All injections were completed from inside the pole barn with a crew member on the outside to alert us when product broke through the ground. First, we injected in the back corner which had the 3” drop. The plan was to establish a base slab height on the side with the most soil problems and then level everything else to that slab. Spacing between injection points was approximately 3-4 feet, with 38 total injection locations.

Rapid Result

The ETRU Spray Foam and Coatings crew achieved a three-inch lift and was able to bring all the other slabs within 1/8” from the adjoining slab. The customer was extremely happy with the results.

Unstable Loading Dock Slabs

The soil beneath a loading dock slab needs to be stable and strong on a consistent basis.  Sinking or rocking slabs can cause injury and litigation risk that no property owner should have to deal with.  The good news is that you have a choice, even if your slabs are not sinking or rocking yet!

Loading Dock Slab Repair with Polyurethane

As the premier manufacturer of polyurethane lifting and stabilization products, we sell to slab repair contractors all over North America.  Wherever your property is located, we likely know a contractor in your area who can provide an estimate for repairing your loading dock.

Alchemy-Spetec's network of factory-trained contractors can fill voids, stabilize soil and lift sunken slabs with high-strength polyurethane foam.

If you own or manage a building with loading docks, do NOT ignore the risk of injury and litigation that stems from unsupported, unstable or sinking slabs.  We can help you find a well-trained contractor, specializing in loading dock concrete repair.

Why Voids Under Your Slabs are Dangerous

If you own or manage a property with concrete slabs, you need to understand the danger posed by voids in the supporting soil. Large gaps in the soil beneath your slabs are a red-alert problem for a couple of key reasons:

• Any equipment or vehicles on your slab are at risk. We have linked to this video before, but it is very relevant here: click to view cars falling through a collapsing floor. You definitely do not want this happening in your warehouse, parking area, showroom or garage.
• People are more valuable than any vehicle or piece of equipment could ever be. Don't put your employees, tenants, customers, friends or family at risk.

Signs You Might Have a Void Under Your Slab

There are a few key indicators you should look for when trying to determine the stability of soil underneath your garage:

• Are there cracks in your slab?
• When you gently tap on your slab with a hammer, does it sound "hollow"?
• Is your slab sinking?

Filling the Void and Repairing the Slab

The good news is that filling voids with high-strength polyurethane is generally an efficient fix when you're dealing with a qualified contractor. And you can use the slab in as little as 45 minutes after the repair job is done. If you find any of these signs of distress, call Alchemy-Spetec at 404-618-0438 or fill out the form linked below for help finding a geotech contractor in your area.

Concrete Leveling & Stabilization for Showroom Floors

Do you own or manage a business with concrete showroom floors? Auto dealers, large wholesale stores, convention centers and other businesses need strong and stable floor slabs to function properly. Unstable slabs can put merchandise, customers and even ownership at risk.  See our two-part blog series on trip hazards and litigation risks...
Concrete Leveling to Prevent Trip Hazards & Litigation Risks - Part 1
Concrete Leveling to Prevent Trip Hazards & Litigation Risks - Part 2

You should also understand the larger danger of complete slab collapse if the voids underneath your floor are large enough. See this stunning security cam footage from the National Corvette Museum for an example in action. Ownership was completely unaware of the large voids that eventually caused this showroom floor to collapse, taking all those Corvettes with it.

Concrete Leveling & Stabilization Contractors

Alchemy-Spetec can help you find a contractor to detect, level, and stabilize slabs at risk. Even if you aren't noticing any immediate problems, it may be worth getting your slabs tested for dangerous voids lurking beneath. Call us now at 404-618-0438 for help finding a contractor in your area!
