Concrete shed foundation cost
in San Francisco.

Measure a shed foundation and keep the slab, base, and footings in one project. Start with the published examples below, then use your own supplier quote for a delivered estimate.

6-sack ready-mix concrete — $219 per cubic yard

Material price. Published 6-sack mix price for a San Mateo County supplier. On-site batches are limited to 1/4, 1/2, 3/4 or 1 yard at a time. Sack count is not a verified PSI rating.

Saved pricing covers one pickup batch of 6-sack material, up to 1 yard. U-cart rental starts at $45 for two hours and is charged again on each dispatch; extra time and cleaning can add charges. Confirm vehicle requirements, availability and tax. Larger quantities or delivery require a separate quote.

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
147 bags

11,760 lb to transport and handle.

Bulk estimateAdd your price

Prices are optional. Tax and additional charges are included only when explicitly entered or covered by the saved terms. Placement labor is excluded. Estimates 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.

Product specifications and assumptions

Saving a reference preserves your inputs. Apply individual values only when they match the product you will buy.

  • Density: 2.025 US tons/yd³ — unverified planning assumption; confirm for this product.
  • Bag yield: 0.6 ft³; bag weight: 80 lb; confirm the selected bag product.
  • Shrinkage: 0% — entered planning allowance; no product-specific compaction rate verified.
Section budget and delivery planning

Destination and timing identify a delivery you plan to share. They do not establish supplier service eligibility. Combined orders are chosen below after saving sections.

Labor, equipment and other project items

All added item prices are your estimates, not researched local rates. Include applicable taxes in these unit prices. Blank charges remain unknown; enter zero only when confirmed. Save the section to update the project budget.

Supplier order terms

Amounts are flat dollar charges for this order. Leave unknown charges blank; enter zero only when confirmed. Weight limits use your entered density. Choosing another supplier clears these quote fields and the delivery location.

Your entered unit price, rounding, delivery, and short-load assumptions apply. Saved supplier minimums and brackets are not automatically enforced in manual quote mode.

Supplier prices & delivery rules

Set an optional weight capacity under Supplier order terms; loads use whichever volume or weight limit is lower. Confirm the payload limit and material density with your supplier. 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. Editing the unit rate switches to manual quote mode.

FROM MEASUREMENTS TO AN ORDER

Plan your concrete shed foundation

What to measure

  1. Use the shed’s foundation drawing to distinguish a full slab from individual pads or piers.
  2. Measure the slab and any separate supports without overlapping their volumes.

Worked example: 10 ft × 8 ft × 4 in

10 × 8 × (4 ÷ 12) ÷ 27 = 0.9877 yd³ before allowance.

10% waste · 0% shrinkage

Neat volume
0.9877 yd³
Volume with allowances
1.0864 yd³

Illustrative dimensions and allowances. Use your project specification and supplier’s product data. Quantities shown are before supplier rounding.

Included in this quantity

Concrete for the example rectangular slab only.

Measure or price separately

Piers, footings, base preparation, reinforcement, anchors, forms and installation.

Choose the specified product

Match the shed manufacturer’s foundation requirements and the project specification. These example dimensions do not select a foundation design.

Before booking the order

Check whether a small-load minimum changes the bulk price. For bags, confirm the exact product yield and include transport and mixing equipment in the budget.
