Many individuals claim that instead of acquiring foam injections, they prefer to replace the whole slab of concrete since they believe it is more advantageous and would last longer. When it comes to repairing concrete damage, you may believe that newer is better, but this is not always the case.
If you choose to have your slab replaced, the new concrete will be poured directly on top of the old dirt foundation, which is a good thing. Without investing the time and resources required to dig, fill in, and compress the soil, those voids will not be fixed. Consequently, the new slab will settle and crack precisely like the previous one, resulting in a similar conclusion.
Slabjacking repairs, as opposed to slab replacement, are more durable in the majority of situations since they treat the root source of the issue. A new slab will provide the effects you want for a short period of time, but slabjacking is more trustworthy and durable in the long run.
