I live in a “C” shaped range home. Within the cavety of the this shape is a five inch thick concrete patio. The overall patio is approximately 10 feet by 27 feet. The home and patio is 50 years old. The patio does not have expansion cuts.
Here’s the problem: The house has settled where one of the inside corners of the patio no longer elevates away from the house, it is now tilting towards the house (there is now an expansion line in the form of a crack). This allows any rain to accumalate and sink in towards the inner foundation. From the crawl space, I can see that there is a crack in the foundation at that point, with a minor leak. Or I think it’s minor The house has settled about two inches there. I have installed jacks in the crawl space to prevent further sagging.
The plan for the summer is to install a wooden deck over the patio, but I want to fix the problem first. My question is this; Can I etch the concrete and pour new concrete to correct this, or do I break up the patio, then pour a new one. In either scenario, How do I seal the foundation? One potential problem with sealing the foundation is that the foundation is rectangled shape under the patio (in other words the entire foundation is rectangle with a smaller rectangle within it sharing one wall). Will this cause an issue with sealing procedures.
The house appears to be stable nevertheless. I want to be on the safe side though. Thanks.
