One of the most common questions we hear in regards to our services is, “So you do foundation work?” Not a bad question. When someone hears “concrete lifting” or “soil stabilization” they naturally think of foundation work, especially in our area where shifting soil is common. Our answer to their questions is “sort of”. We “sort of” do foundation work, but probably not in the sense that you are thinking.
While the polyurethane resins we use are strong enough to lift commercial structures and railway beds and support some of the busiest commercial airport runways in the world (literally countless examples come to mind while typing this) we are more concerned with why the structure shifted or settled in the first place and how we can address and alleviate that issue for good. In some ways, we have a symbiotic relationship with traditional foundation repair companies.
Once a footing has been lifted, you still have a few areas to address:
Voids need to be filled where the structure was lifted
Once lifted, there is typically a void between foundation and soil that must be filled for support. Our structural polyurethane resins are a perfect match for this application. They are lightweight (2.75-3.25 lb/ft3), have a compressive strength of 14,000 p.s.f., and bond with concrete and soil creating a seamless connection.
Why did the foundation settle?
In situations where the foundation drop was due to poor soil compaction or soil matter decomposition, we have several methods to address the deeper lying issues. Our single component polyurethane resin permeates and combines with the soil to create a solid, stable mass under the foundation. Unless the underlying reason is addressed, foundation lift could be futile.
Internal slab issues
Last but certainly not least is internal slab lifting. Our application is perfect for internal slab lifting due to the no mess, low disruption methods we use. Our process uses only a ½” hole to get the material where it needs to go. This means you don’t need to move furniture, demo all of your floors, or move out for any length of time.
Now you know why our answer is we “sort of” do foundation repair. We are interested in addressing the root of the cause, not just what is seen. Be on the lookout for our blog addressing Pre-Construction Soil Stabilization.
