What is curing in foundation?
Assuming you mean a concrete foundation- after concrete is mixed, it undergoes a chemical change. It does not "dry"- it "cures"- and becomes harder. The process takes place over a period of days or weeks- gradually getting harder and stronger.Until it has cured- or hardened- enough, you cannot place heavy weights on it, or the fresh concrete will break. It usually reaches adequate cure within a few days, andnear max cure at 28 days.
