What is PCC in foundations?

PCC stands for Plain Cement Concrete. A thin layer of PCC (usually M10 mix, 3-4 inches thick) is laid at the bottom of excavation pits to create a clean base for steel footings.

What depth is safe for residential footings?

Safe isolated footing excavation depths depend on soil bearing capacity, but a minimum of 4 to 5 feet is standard for residential houses.
