Repair work done not needed

[duped1]

I had a contractor inspect my foundation (slab) and indicated the foundation was settling. They proposed putting in piers and I had them do the work. Now I have someone else indicating no foundation repair was needed. What damage, if any, can be done to the foundation at this point by those piers ?

Contactors and structural engineers utilize visual signs of settlement. Soil borings by a Geo-Tech gives actual findings.

Short of getting soil borings the contractor logs the depth of each pier driven. If soils are at or above 2,500 psi the depth will be very short. Meaning maybe the soil was not the issue. Although sometimes the soil at the footer has good capacity it may get softer with depth.

Contractor should supply you with piering log.

Finally piers do not damage existing structure assuming no damage was done in installation process.

Thank you so much for the information.
