"Northshore responded quickly to our inquiry and was able to complete the structural analysis we needed within a week. We received our report quickly. Everything was thorough and professional."

"very positive. he was candid and knowledgable"

"Very good quality work, custom design, knows the industry practice well. Happy with the final design."

"I called for an estimate in early March and they came out promptly.  The guy took some measurements told me what to expect and gave me an estimate.  The price seemed a little high but I have no idea what it costs to raise concrete or cost of materials for the company.  The thing that sold me on them was the fact that they use a concrete slurry instead of just mud (hence the term mudjacking).  The estimator explained that they don't do mudjacking because mud eventually breaks down and you get the same problem again.  If you google the term mudjacking and read reviews like I did you will see a lot of people complaining about the problem returning.  So I liked the fact that CRC used concrete slurry rather than just mud.  I thanked him and told him I would call them when I was ready (scraped together enough money).
    So I called them at end of April and sent in a deposit.  They scheduled me right away for the following week on Tuesday May 7th.  They called the day before and confirmed appointment for 8am the next day.  On Tuesday they arrived a little after 730a and started prepping their equipment.  Once they started drilling I could see what they were dealing with.  The slab was done poorly when it was originally poured.  It had varying thicknesses among the different holes which made me a little nervous on how successful they would be in getting the stairs heading down to the garage to come up with the slab.  The workers were nice guys, polite, but for the most part I left them alone to do what they had to do.  At one point, they rang the bell and asked me to come out and look at something.  When they had tried to drill through the top step heading down the garage it had cracked and split the whole step (tread and riser).  They tried a second hole and it split again.  The head guy explained to me that the original concrete on the stairs just wasn't strong enough to hold up to the stress of the drill (about a 2 inch bit) so that they were going to try their best to raise the stairs and drill every other step rather than 2 holes per step.  I agreed and they went to work.  About an hour later they were done.  The main slab came up great and filled the 3 inch void that was there prior.  The stairs on the other hand looked a little wonky.  For the most part they leveled out but that top step looked pretty bad with the cracks and it high on one side.  The head guy explained that they were sturdy and full of the slurry, but looking down on them, it looks like each step is going in a different direction level wise.  The crew cleaned up the mess pretty good but left some slurry blobs on the stairs and in the corners that I easily chipped away at and cleaned up myself a few days later.  My neighbor has an epoxy concrete finishing business and he's going to help me coat the surface of the slab and hide the patches from the drilling.  Overall a good experience, but I would have rated them a notch higher if those stairs came out better.  I know they can only do what they can do with someone else's poor work, but now I have to refinish that top step so it looks smooth.  Structurally the stairs are fine and I never use that entrance to my garage so not a big deal.
