The Problem- Why Concrete Sinks
Concrete slabs sink due to soil compaction or voids created by erosion. In Kansas City’s typically dry climate, soil loses moisture and shrinks, causing uneven settling. Winter freeze-thaw cycles and improper drainage can exacerbate the problem. Early detection and repair are key to cost-effective solutions.
One of the most common questions customers have is how long this foam jacking will last? It’s a fair question considering you’re making an investment in your property. Polyurethane foam doesn’t break down, doesn’t absorb water, and won’t compress over time. Jason and Ken have been doing this work since 2012. They are very confident in the permanence of this solution that they guarantee their work for two years.
The Foam Jacking Process
When they show up to fix your driveway, they bring a truck with the foam injection equipment. They don’t bring a jackhammer or a concrete saw or any of the loud, messy equipment you’d associate with concrete work. They drill holes about the size of a penny, maybe five-eighths of an inch, and they are strategic about where they place them. Then the foam is injected through those holes, and you can literally watch your concrete start to rise as the foam expands underneath. The foam reaches about 90% of its full expansion in about 15 seconds. Within thirty minutes of us finishing, you can use the driveway again. Most of their residential jobs are done in under four hours from start to finish.
How Traditional Mudjacking Works
Traditional mudjacking involves drilling large holes in the concrete and pumping a heavy mixture of dirt, water, and cement to lift the slab. This method is messy, prone to settling, and may have to be redone in the future. The heavy equipment may disrupt or damage your lawn or property at the location of the sunken concrete.
Easiest Way to Get an Estimate
The fastest way to get an accurate quote is to show the team at Concrete Raising Systems what you’re dealing with. Take a few photos of your concrete from different angles, and use the form on the contact us page to send them along with some basic information. If you’d rather talk through your concrete repair issue, just call 816-419-8306. Either way works for them. They can’t always give a quote over the phone. Lots of times, they need to do an assessment of the work on site.
