Re: Care of concrete patio, stress relief grooves cracked and opening
Howdy maintenance of adding a non hardening high quality concrete expansion caulk is a best practices. The best is self leveling that never set up hard. Concrete redimix suppliers have it and the big tube is the best cost wise. The box store stuff in my experience simply does not last. This quality caulking moves with the concrete expansion cycles. If you live where it freezes then to avoid freeze and thaw damage it is a must almost a must. lol
Any an all of my comments are just my opinion and not to be confused with facts.
