Is Mudjacking or Polyurethane Injection Better?

Foam Jacking Advantage

Polyurethane is a quicker, more efficient and water-resistant way to repair concrete. Unlike mud jacking, when the polyurethane is injected it expands under the surface and fills voids to create desired support. Polyurethane is lightweight and will not wash away or lose density over time, which are common downsides to mud jacking.

Poor Compaction

When your home is being built it is usually surrounded by loose soil and backfill. Most homes in Alberta have basements. When the basement is being dug out the area around the foundation is over-excavated to allow for the form work to be installed. Once the basement walls have been poured the area is “backfilled”. This loose fill is not compacted causing it to settle over time. This area is then prepped for sidewalks, driveways, patios, garage pads and basement floors. The lack of adequate compaction in these areas ultimately leads to sinking concrete and voids.

Water

Water influences soil compaction. A home that does not have proper drainage, combined with typical rain and snowmelt, will see erosion and the closing of any open-air pockets. This will cause the soil to collapse in on itself subsequently resulting in the sinking and cracking of concrete and void formation. Pipe leaks, burst pipes or overwatering of your lawn may cause the same effects. Here at TCB Foam Solutions, the polyurethane foam we use is water-resistant which can improve underlying water issues that cause the problem in the first place.
