Concrete Raising of NC Answers Your Frequently Asked Questions
Can all concrete be raised?
Approximately 95% of sunken concrete can be raised.
Can concrete that has been raised sink again?
We have found that approximately 5% of our jobs have continued to settle. We will return and continue to raise these slabs for one year. After that time, we will return and continue to raise for a reduced fee. This warranty is limited to settling from ¼” to 1”. More extensive settling would require additional deep grouting services.
