Material & project assumptions

Density and bag values are editable planning assumptions. Confirm the product label or supplier specification.

Reinforcement quantities follow your inputs, not a structural design. Base volume excludes its own waste and compaction. Trench fill does not subtract pipe displacement.

Bagged or bulk?

Same project. Two ways to get it done.

THE BAGGED APPROACH
48 bags

3,840 lb to transport and handle.

Material estimateAdd your price
THE BULK APPROACHLess handling
1.25 cubic yards

1 estimated load at your truck capacity.

Bulk estimateAdd your price

Prices are optional. Estimates exclude taxes, placement labor, and unentered supplier charges. They are not supplier quotes.

User-entered supplier prices; delivery and tax require confirmation.

No detailed supplier conditions were saved. Confirm delivery and other charges before ordering.

Supplier prices & delivery rules

Truck capacities here are volume limits. Confirm legal payload by weight separately. Short-load fees apply to each load below your threshold. Base material and rebar costs are excluded.

Entered delivery fees: $0.00 · Short-load fees: $0.00

Use a researched supplier price

These are product-specific examples, not regional averages. Applying one sets the listed unit rate. Review delivery, minimum-order and density terms before using the totals.

4000 PSI ready-mix, standard 2B stone · $140.00/yd³

Material price. GSI Concrete — 2026 Pennsylvania-only supplier price list. This is a mix-specific material example, not a prescribed mix strength or installed price; confirm your design specification. The supplier meters and bills actual usage; order rounding here is a planning allowance.

The page lists $350 per truck for the Philly area, $110 extra on Saturday, and $3/minute beyond one hour. It also lists zone charges; confirm which charges apply, truck capacity, and minimums before ordering.
