The PolyRenewal system is more effective at targeting the source of the issue, while also working to prevent future problems down the road. In contrast, mudjacking can fix uneven and sinking concrete slabs, but it does not address the origin of the issue, which is soil shrinkage, compaction, and settling.
Downsides of Mudjacking
Mudjacking is one of the traditional ways to level out concrete. This is performed by contractors, who begin first by drilling a soda can-sized hole into the concrete. A mortar-based mixture, also known as mud or slurry, is then funneled through this hole into the ground. After a few days, this slurry will be cured and your concrete will be as good as new.
Or so you think. Remember that soil compaction can result from excessive weight. This can eventually lead to soil settlement. With that in mind, consider the fact that the mudjacking slurry is quite heavy. While it can level out your concrete, it will weigh on your soil even more, causing more cracks and slabs to become uneven.
Benefits of the PolyRenewal
The PolyRenewal system is extremely versatile. Because it’s lightweight and can set up in under an hour, it does not bear down on already weak soil. Instead, it works to lift and support your concrete, giving it the structure it needs without disrupting the compacted, shrunken, or settled earth more than necessary.
This foam does not require large holes to be funneled through and is therefore less invasive. Because it is waterproof, it will not be affected by any pooling water from the compacted soil, nor will it make the problem worse by expanding or cracking itself. It has an impressive lifespan, making it a one-time solution rather than a temporary fix that needs updates or maintenance.
