Calculators
Concrete doesn't work alone. These 14 calculators cover the materials that go alongside it — gravel sub-bases, sand, mortar, CMU blocks, brick, pavers, asphalt, mulch, and more. Get accurate volume, quantity, and tonnage estimates without guessing.
Every Material That Works Alongside Concrete
From the gravel that goes under the slab to the pavers that go on top of it, these calculators cover the full supporting cast.
Calculate volume and weight of gravel, crushed stone, or recycled aggregate for driveways, sub-bases, drainage layers, and landscaping. Outputs cubic yards, cubic feet, and tons.
Volume and tonnage for concrete sand, mason sand, paver bedding, and fill. Enter area and depth; get cubic yards, cubic feet, and tons with optional waste factor.
Estimate topsoil volume in cubic yards and cubic feet for lawn installations, raised beds, and grading. Includes bulk and bag count conversions.
Compute fill dirt volume for low spots, backfill behind retaining walls, and site grading. Accounts for compaction shrink factor.
Calculate mortar quantity for brick, block, and stone laying by wall area or unit count. Supports Types S, N, and M mortar mixes.
Enter wall dimensions to get exact CMU block count (8×8×16 standard or custom sizes), mortar volume, and optional core fill concrete. Adds configurable waste factor automatically.
Calculate grout or concrete needed to fill CMU cores by wall size, block type, and fill pattern (every core, alternate cores, or bond beam only).
Count bricks needed for walls, facades, and paving by area. Supports standard, modular, and queen brick sizes with mortar joint adjustment and waste factor.
Calculate paver quantity for patios, driveways, walkways, and pool decks by project area and paver size. Includes sand bedding and polymeric joint sand estimates, plus a configurable waste percentage for cuts.
Estimate segmental retaining wall block units, cap blocks, and gravel backfill by wall height and length. Supports standard Allan Block and similar systems.
Calculate tons of hot-mix asphalt for driveways, parking lots, and road patches. Outputs tonnage by area and compacted depth using standard HMA density.
Volume estimator for wood chip, bark, rubber, or stone mulch by bed dimensions and depth. Outputs cubic yards and standard 2 cu ft bag count.
Estimate polymeric jointing sand for paver projects by surface area, paver size, and joint width. Outputs pounds and standard bag count.
Volume and tonnage for RCA sub-base material with cost comparison against virgin crushed stone. Includes compaction factor and estimated CO₂ savings.
Why Adjacent Materials Matter as Much as the Concrete Itself
Every concrete project sits on, around, or next to other materials. A garage floor slab needs a compacted gravel sub-base — get that volume wrong and you're paying for material you don't need or under-building the foundation. A patio needs sand bedding for pavers and polymeric joint sand to lock them in place. A retaining wall poured from concrete needs fill behind it and drainage aggregate to manage hydrostatic pressure.
These calculators exist because concrete estimating tools routinely ignore the supporting materials — even though in many projects, gravel, sand, or brick represent 30–50% of the total material cost. Getting them right before you order matters just as much as nailing the concrete volume.
Each calculator here uses industry-standard densities, unit weights, and coverage rates. Results are given in both imperial and metric, and every tool includes a configurable waste factor because job sites aren't textbooks — material gets lost, broken, or unevenly applied. Use these alongside our Flatwork, Foundations, and Cost calculators for a complete project estimate.
Built for Every Level of Project
From weekend DIYers ordering a pallet of pavers to GCs estimating a full commercial site — these calculators work at every scale.
Homeowners & DIY
Ordering a pallet of pavers or a few yards of topsoil is expensive to get wrong. These tools let you calculate exactly what you need before you're at the checkout counter.
Contractors & Builders
Bid materials confidently. Run CMU counts, mortar volumes, and gravel tonnage for proposals in minutes — then hand the numbers directly to your supplier.
Estimators & Engineers
Cross-check takeoffs, verify supplier quotes, and compare recycled aggregate vs virgin stone costs — all with references to the ASTM and AASHTO standards you're already working to.
