Planning a basement slab or garage floor? The compacted gravel base underneath is what keeps it from settling and cracking. We use at least 4 inches of crushed rock, compacted in layers, before any concrete gets poured.
Skip this step or rush it, and you'll see uneven settling within a couple years. A solid base means your slab stays level and crack-free for decades.
