What product to use when filling the gap left after the slab has shrunk?
I went to the big box store and purchased Sika polyurethane foam for concrete and masonry. Will this work or should I use another product? I plan on using a Sika concrete caulk sealant made for sealing cracks in foundations for the narrow areas. Oh by the way, I want to thank GBA for all of the advice I got when building our house in PA.
