How To Lift A Sinking Concrete Slab With Foam In Poway Ca?

7 Tips To Lift A Sinking Concrete Slab With Foam In Poway CaConcrete slabs can sink for many reasons, including soil erosion and improper installation. Fortunately, there are several methods to repair a concrete slab that has begun to sink. One such method is the use of polyurethane foam injection technology, which is becoming increasingly popular due to its cost-effective, reliable results. Here are 7 tips to lift a sinking concrete slab with foam:

  1. Before beginning your project, ensure you clear any vegetation or other objects from around the affected area. This will make it easier for you to access and inspect the slab later on in the process.
  2. Inspecting the slab before lifting is also important because it helps you identify any potential problems that may be causing it to sink. Check for signs of soil erosion, water infiltration and poor installation.
  3. In order to lift the slab with foam, you will need to create access points near its edges. This will allow you to inject the expanding polyurethane foam later on in the process.
  4. Any cracks or gaps in the slab should be sealed with a high-quality sealant before injecting foam into them. This will ensure that the expanding foam does not escape from these weak points or compromise your repair results.
  5. Using specialised equipment, drill small holes around the perimeter of the slab and inject polyurethane foam into them until they are full. The foam should slowly fill the voids and gaps beneath the slab, lifting it back into place.
  6. Once you have injected all of the foam, leave it to dry for at least 24 hours before inspecting your work or allowing anyone to walk on it.
  7. Finally, inspect the area again once everything has dried to ensure that the slab is securely in place. If necessary, apply a fresh layer of sealant to protect against water infiltration or further soil erosion.


Does Lifting Concrete With Foam Last?

Yes. When applied correctly, the foam will expand and fill in any voids beneath the slab, lifting it back into place with a secure hold that can last for many years.

Are There Any Special Tools Needed?

Yes. You will need specialised foam injection equipment to safely and effectively lift your concrete slab with foam. It is best to consult an experienced professional if you are not familiar with this type of technology.

Can I Do This On My Own?
