With 10% waste buffer
-
1 cubic yard = 27 cubic feet. The 10% buffer is a common rule of thumb for slab pours to cover sub-grade irregularities, spillage, and form deflection - adjust it up for a smaller or more irregular pour, since the buffer matters more on small volumes. Always confirm with your supplier before ordering.
