One thing most people don't consider is the erosion going on underneath concrete slabs. Storms come with an alarmingly large amount of water. Although most travels on the surface of the concrete to drainage; a portion flows underneath and creates some serious issues for the concrete above. As the water resides and goes down and or out, it takes sediment with it. The process of eliminating the underlying soils creates voids and/or cavities under the slab. Water also breaks bonds between compacted soils and can loosen compacted soils.
Depending on the pour of the concrete; it can react in different ways. If the concrete is poured thick and has strong reinforcement, it will act more like a bridge over the new cavity created by erosion. If the concrete is poured thin and no reinforcement, it will likely sink with the soil and break apart as it does so.
Polyurethane foam injection is a great solution for all concrete slabs!!! Filling the voids and cavities created by erosion is a sure way to stabilize the soils underlying concrete slabs. Soil stabilization is the main goal for any structural injection. However, with the new polymers we can achieve lift in just about any scenario. Concrete that has a void under and is causing cracking, can be solved by a simple high density polyurethane foam injection. This process can not only solve your problem but also increase the life of the concrete. Is a great alternative to replacing slabs with simple compaction failure.
The foam does not just fill these voids!!! The Polyurethane is a two part polymer meaning; it mixes and expands under the slab. This process allows us to re-compact the surrounding soils during this process. Cant lift without first compacting what your lifting off of!
