Tailles courantes de dalles beton et verifications d achat
These examples use 4 inches of concrete and 10% waste. Use them as a planning screen before deciding whether the pad is a bag project, a ready-mix order, or an installed quote that needs a scope review.
| Exemple de dalle | Réponse en béton | Parcours d achat probable | Vérification de portée |
|---|---|---|---|
| 4x4 AC pad | 0.22 yd3, about 10 80-lb bags | Usually bag-friendly | Check equipment clearance, slope, vibration, base, and service access. |
| 6x8 trash pad | 0.65 yd3, about 30 80-lb bags | Bags or mini-mix | Check access, cleanup, slope away from structures, finish, and disposal. |
| 8x10 shed pad | 1.09 yd3, about 49 80-lb bags | Compare bags vs truck | Check shed manufacturer size, gravel base, drainage, ramp, and anchors. |
| 10x10 hot tub pad | 1.36 yd3, about 62 80-lb bags | Ready-mix or contractor review | Confirm filled weight, reinforcement, drainage, electrical clearance, and installer requirements. |

Concrete pad decision checklist
Use this table when the pad is small enough to look simple, but the use case or jobsite path can still change the real cost.
| Signal to check | What it means | Next step |
|---|---|---|
| Pad size and thickness | Length x width x thickness gives yd3, m3, and bag count after waste. | Confirm finished pad size, not only equipment footprint, and round up to supplier ordering increments. |
| Use case and load | AC, trash, shed, generator, hot tub, RV, and equipment pads can require different thickness, base, drainage, or reinforcement. | Ask the manufacturer, installer, engineer, or local professional before treating load-bearing pads as simple slabs. |
| Base and drainage | Small pads still move when base depth, compaction, slope, drainage, or poor soil are ignored. | Ask whether excavation, gravel, compaction, geotextile, slope, and drainage correction are included. |
| Bags or delivery | Once bag count climbs above the easy mixing zone, delivery minimums, short-load fees, and access may beat bag labor. | Compare bags, ready-mix, mini-mix, volumetric, and wheelbarrow or pump paths before checkout. |
| Quote wording | A quote that says concrete pad may omit forms, reinforcement, finish, curing, cleanup, disposal, permits, or warranty limits. | Normalize each bid into line items before approving the lowest number. |
