Brick and masonry is typically 1900 lbs/yd3. A 4 yd3 load is about 2.8 to 5.0 tons (typical 3.8 tons). Brick and masonry behave as heavy debris with strict hauling constraints. Safe plans usually use controlled fill and separation checks.
Brick and masonry is usually a weight-first decision surface. Treat volume as secondary after tonnage limits.
