CRC has repairs that are over twenty years old which haven’t moved; however, we also have warranty work. Consider the slabs we work on. There are panels that took over fifty years to move and others that aren’t even a year old.  These disparities are sometimes easy to explain such as a pipe failure or a tree next to a slab. But, the true reason is usually a bunch of little factors that lead to the problem.

I like to say past performance is usually indicative of future performance.  If a slab took five years to fail, then odds are our repair will start to move in about five years.  Now some will say this is a failure, but if you instead went with tear out and replacement the odds would still say that the new slab will move in about five years. The truth is you are where you are, and the soils in that particular area are going to do what they want to do.  Of course, there are usually ways to engineer around most of these issues, but for residential or commercial projects the cost is usually prohibitive.

So, where does that leave us. We have repairs that are long term fixes, and we have others that are just managing issues (soils, trees, drainage, etc).  Looking at the problem from a cost perspective you should try to extend the length between tear out and replacement as long as possible. Imagine a leaky roof. Sometimes you just need to patch the leak and other times you need a new roof. That is where our repair fits in. Our method of repair extends the useful life of your concrete, but the time between repairs is dependent on the soils underneath.  After all we are just along for the ride.
