Will existing cracks disappear?
- Lifting reuses the current concrete, so existing cracks can remain.
- Weathering and discoloration may also remain after the slab is raised.
- Lifting does not create a new slab, so a like-new appearance is not guaranteed.
What about injection holes and patches?
Access holes are patched after lifting, and the patches may look different from the older concrete around them. Discuss the actual method and the finish you can expect for your slab, rather than assuming the repairs will be invisible.
When does appearance change the decision?
- If a new layout or surface is the result you want, lifting alone may not reach it, and replacement may fit better.
- If remaining cracks, weathering or discoloration would bother you, compare that with what a new pour would look like.
- Ask whether crack or joint work is included in the written scope or excluded from it.
- Do not assume cosmetic treatments are part of lifting.
