At Foamworx we use hydrophobic geotechnical polyurethane foam to repair, raise, and level concrete slabs, fill voids, and repel water. Using the polyurethane foam method results in a waterproof repair that’s also environmentally friendly!
You may be asking yourself, “But can you fix foundation problems with foam?” If you’ve ever struggled with foundation problems before, you know that traditional slab raising can take days, or even weeks, to complete. And it almost always involves digging up the entire foundation and removing people from the home or place of business under construction.
Our polyurethane foam can accomplish the same job in a matter of minutes… or in a few hours tops, depending on the size of the job.
Can You Fix Foundation Problems with Foam Foundation Repair Methods?
Our specially engineered geotechnical polyurethane foam is pumped under pressure into small holes drilled through your existing concrete slabs. The foam then repels water, displaces air pockets, fills voids underneath the slab, pushes back water-saturated materials, lifts the slab, and creates a firm, permanent subgrade for your foundation.
Unlike traditional concrete foundation repair and lifting, the foam method requires little equipment: a single truck or trailer holds all the materials and supplies needed. The main piece of equipment is the very long hose we use to pump in the foam. Our crew members pull the hose to the repair area and inject polyurethane foam underneath the slab to fill voids and raise it to the appropriate level.
Our methods are the same for both commercial foundation repair and house foundation repair techniques.
Geotechnical Applications for Polyurethane Foam Slab Lifting
High-density polyurethane foam is useful for lifting slabs, repairing sidewalks, and filling cracks and voids with waterproof support. The geotechnical applications include:
Freezing, faulty foundations, improper installation–there are many causes of concrete damage. Epoxy injections can repair this damage and restore your structure with a minimum of interruption to your everyday life.
Lightweight Fill Systems
In order to fill very large voids or utility trenches underneath concrete slab sections, we can perform an injection fill or lightweight spray over polystyrene blocks or more conventional lightweight concrete mixes. Our light spray is high-strength, low-exotherm, low-density, and fast-drying.
Pipeline Trench Breakers, Pads, and Pillows
We use low-exotherm, low-density spray foam when we construct pipeline breakers and pads as an alternative to traditional sandbag breakers. This gives us incredible dimensional stability in a fraction of the application time.
Our skilled and highly-trained technicians are able to handle unique or difficult polyurethane applications. We can help you full annular spaces around and inside of different kinds of liners and pipes. We have also filled double-wall tank linings, decommissioned pipe and culvert systems, and underground storage tanks. Before you give up, give us a call! We’re happy to offer you a free consultation.
DOT and Highway
We have specific polyurethane polymer formulations in varying compressions, tensile strength values, and flow meant for highway and DOT repair. We can level, lift, fill, and underseal roads, streets, and highways. We also offer repairs for bridge approaches and departures.
The Foamworx method can make infrastructure repairs as well as repairs to precast maintenance holes. Our specialized formula seals leaks in misaligned joints and fills voids on the exterior caused by erosion or poor soil compaction.
Sinkholes and weak soil compaction can cause your foundation to shift, sink, or crack. Our team will inspect your property for warning signs of sinkholes and then help you fill and repair the damage.
Foam Foundation Repair Cost
The cost of foam foundation repair can vary wildly depending on the scope of your project and the depth of damage being repaired. More foam and more time will cost more money. But in general, it ranges from $5-$25 per square foot depending on what type of foam is needed and the location of the repairs.
Estimates will vary based on your subsoil conditions, excavation costs, and the volume of the gaps being filled. You’ll have to contact a professional to get an accurate estimate of your foundation repairs.
How To Fix Foundation Problems
You won’t be able to fix foundation problems on your own, but what you can do is learn to spot the signs of foundation distress, and then contact a professional as soon as possible to prevent the problem from worsening.
First, check the exterior of your home for the following signs:
- Wall rotation
- Separation around the windows, walls, or garage door
- Cracked bricks
- Cracked and/or broken foundation
- Displaced moldings
Then check indoors for:
- Misaligned doors and windows
- Cracks in the sheetrock
- Cracks in the floor
- Uneven floors
If you notice any of these signs of foundation distress, call a foundation repair company immediately. The sooner you repair the damage, the less expensive it will be to fix it.
What Causes Foundation Problems?
60 percent of homes built on expansive soil experience foundation damage of some kind. Cracks occur when only part of the foundation settles or heaves. The uneven movement in different sections of the slab is usually caused by differences in the soil moisture.
Gain or loss of soil moisture causes swelling or shrinkage, which can cause cracks. Settlement cracks are almost always vertical. Do not confuse them with cracks caused by lateral movement due to soil pressure.
The vast majority of foundation problems are caused by water or moisture damage in some shape or fashion.
You are more likely to get foundation damage if:
- Your home is built on expansive clay
- Your home is built on improperly compacted fill soils
- There is poor drainage around the foundation
- You live in an area with extreme seasons or temperatures
- You have a plumbing leak below your home
- There are tree roots close to your home
- An earthquake, flood or drought compromises the infrastructure
If you have any questions about polyurethane foam foundation repair, or if you notice any signs of foundation distress around or in your home, contact Foamworx. We’ll send an inspector to assess your property and schedule any needed repairs.
