All: Am going to pour a concrete patio about 24X30 ft. 4 inches thick.
How large should the individual sections be to minimize cracking? How to separate the sections? I’ve seen all sorts of schemes, ranging from 1X4 embedded in the slab to galvanized strips to saw kerfs cut in the slab after it cured. What is the best approach?
Don.
