100 sq ft slab component estimate
For a 100 sq ft slab at 4 inches thick, the concrete anchor is about 1.36 yd3 with 10% waste. The useful estimate then adds base, forms, reinforcement, vapor barrier, joints, tools, delivery, and quote exclusions before you buy.
| Composant | Quantité de planification | Vérification du devis |
|---|---|---|
| Concrete | 1.36 yd3 / 1.04 m3, or about 62 common 80-lb bags | Confirm waste, bag yield, truck minimum, delivery fee, and short-load terms. |
| Gravel base | About 1.23 yd3 loose base for 4 in depth before compaction | Ask whether excavation, haul-off, compaction, drainage, and base repair are included. |
| Forms | About 40 linear ft for a 10x10 slab perimeter | Check board height, stakes, form removal, edge detail, and cleanup ownership. |
| Rebar or mesh | Scope-dependent; use slab rebar takeoff for bar size and spacing | Require bar size, spacing, chairs, laps, mesh or fiber substitution, and inspection timing. |
| Vapor barrier | 100 sq ft plus overlap and penetration allowance when needed | Check barrier thickness, seams, puncture repair, and whether the slab use requires it. |
| Joints and curing | Saw-cut/control-joint plan plus curing supplies | Confirm joint spacing, saw-cut timing, finish, curing method, and warranty assumptions. |

Concrete slab component checklist
Use this table when a volume calculator gives the concrete amount but the actual slab order or bid still needs component-level scope.
| Signal to check | What it means | Next step |
|---|---|---|
| Concrete volume | Length x width x thickness plus waste gives yd3, m3, ft3, and bag count. | Confirm product yield, ready-mix minimum, delivery fee, and whether the quote bills usable or minimum yards. |
| Gravel base | Area x base depth gives base volume before compaction, haul-in, and grading assumptions. | Ask whether excavation, compaction, drainage, geotextile, and base repair are included. |
| Forms and stakes | Perimeter drives form boards, stakes, layout time, edge accuracy, and cleanup. | Require form height, edge detail, form removal, and who owns correction work in writing. |
| Rebar, mesh, or fiber | Reinforcement choice changes material, labor, chairs, laps, inspection timing, and approval responsibility. | Use the slab calculator rebar takeoff or ask the contractor to specify bar size, spacing, mesh, fiber, chairs, and substitutions. |
| Vapor barrier and joints | Garage, shed, basement, and conditioned-space slabs often need moisture and joint decisions before the pour. | Check barrier thickness, seams, penetrations, saw-cut timing, curing, finish, and warranty responsibility. |
| Access and delivery | Chute reach, wheelbarrow distance, pump/buggy needs, wait time, and washout can change the delivered total. | Run the delivery, pump-vs-wheelbarrow, or quote reviewer workflow when the path from truck to forms is unclear. |
