Void Filling – Prevent Damage and Save Money

The term “polyjacking” is an industry specific term that refers to using polyurethane foam to jack up a concrete slab. However we can use our “polyjacking” technology as a preventative measure to stabilize a slab before it has begun to sink or crack. We call this “Void Filling”.

After reading our previous blog: “Polyjacking vs. Mudjacking”, you now understand that concrete will sink or crack due to voids beneath the slab. Poor soil compaction at the time of concrete placement, water erosion, improper water drainage, and drastic changing weather conditions will speed up the time it takes for these voids to form beneath concrete. There are many cases where we see voids forming beneath concrete, and are able to fill these spaces with our polyurethane foam before the concrete is significantly damaged. 

Let’s think about a front porch as an example. A homeowner notices that they can see a space growing beneath their front porch. It becomes a bit of an eye sore so they go to the local home and garden store and pick up a couple bags of topsoil to fill the space and get rid of the eye sore. Problem solved… until about one month into the rainy season, this area has already washed away and grown even bigger. Every heavy rainfall that passes through the area, the homeowner notices the space keeps growing. The homeowner realizes that simply filling the space with loose soil will not be a good fix for this issue.

Now the homeowner turns to google for solutions to this problem, and they find a local polyjacking company that can successfully fill this void with polyurethane foam. The homeowner calls this local company to set up a free estimate, and they have now started the process of potentially saving thousands of dollars in the future. 

Void filling with polyurethane foam is extremely effective for many reasons. 

1. The foam injected beneath the slab will slowly expand. This allows it to fill all nooks and crevices which maximizes stabilization and prevents future sinking and cracking. Traditional mudjacking uses a grout based mixture that will not expand, and simply mound up beneath the injection point.
2. The foam used does not erode like soil or traditional mud in mudjacking. Once that foam is set up beneath your concrete, it is there to stay. However, soil around the foam is still susceptible to erosion, so it is important to maintain proper water drainage away from the concrete. 
3. For homes with basements: filling a void beneath your porch will remove spaces for water to collect and cause water leaks or foundation settling. Which can save thousands of dollars in the future. 

Proactive homeowners understand that their home is an investment. Using preventative measures to save concrete is a great way for proactive homeowners to protect their investment in their home. Filling voids beneath your concrete is one of the most effective ways to prevent future problems that can cost thousands of dollars. Don’t hesitate to call us if you have any questions about how the process of void filling with polyurethane foam can help you protect your investment.
