Concrete Lifting and Leveling - Sunken Walkway Creates High Step in Saint Louis, MO

Concrete slabs are heavy and over time the soil underneath the concrete may not be able to support the weight anymore. This is what happened with this Saint Louis, MO homeowner's walkway. The slab of the walkway had sunken over the years and pulled away from the step above. Unexpected high steps like this can pose tripping and falling hazards that might result in an injury. There are multiple reasons that this can happen but one major reason is soil underneath the slab compacting under the weight of the concrete due to soil type or soil that wasn't compacted properly at the time of installation. Woods recommends PolyLevel injections for situations like this where concrete has sunken to lift it back to even with the step.
