Masonry, Stucco & Hardscape: Calculators, Diagrams & Guides
5 calculators · 15 diagrams · 2 guides
Masonry and hardscape estimating is unit math layered on earthwork: bricks per square foot with mortar bags to match, three coats of stucco each with its own thickness and mix, pavers over a compacted base that outweighs the pavers themselves, and asphalt ordered by the ton against a volume you measured in inches of depth. The five calculators in this hub each own one of those takeoffs, from brick and block counts through bedding sand and driveway tonnage.
The diagrams expose the layers that get buried: running bond coursing with standard modular dimensions, the three-coat stucco system (scratch, brown, finish) over lath and weep screed, a paver section from subgrade through compacted base to bedding sand and edge restraint, and the asphalt driveway stack with its stone base doing the real structural work under the surface course.
The numbers track ASTM and industry specs — C270 mortar proportions, the 6.75-brick-per-square-foot modular convention, ICPI base-depth guidance for pavers by traffic load, and compaction factors that turn loose cubic yards into placed depth. All five calculators are free with no signup, and the paver and asphalt driveway guides walk the full build sequence from excavation through compaction, edge restraint, and final joint sanding.

Brick bond patterns compared — running, ⅓ running, stack, common, English, and Flemish
The common brick bonds: running (½ offset, the standard), ⅓ running, stack (aligned — needs reinforcement), and the header-bonded common, English, and Flemish bonds that tie a double wythe and so use more brick.

Where bricks-per-square-foot comes from — the nominal brick-plus-joint cell
A brick plus its ⅜″ joint is a nominal 8″ × 2⅝″ cell (21 in²), so 144 ÷ 21 = 6.75 bricks per sq ft. Tighter joints mean more bricks (¼″ → 7.34, ½″ → 6.40); bigger units mean fewer.

Anchored brick-veneer wall section — air space, WRB, ties, flashing, and weep holes
Brick veneer is a non-structural skin hung on ties over a 1″ air space, not a load-bearing wall. Rain that gets behind it runs down the WRB onto the base flashing and out the weep holes — so never seal the weeps.

What goes under pavers — compacted base, bedding sand, joint sand, and edge restraint
A paver field is mostly the buried layers: compacted base (4″ patio · 6″ driveway · ~10″ vehicular), a screeded 1″ bedding sand (never deeper — it ruts), pavers, polymeric joint sand, and a spiked edge restraint. Pitch it ~1.5–2% to drain.

Paver laying patterns — running bond, herringbone, basketweave, and waste factors
The pattern sets the waste factor and the strength: running bond (~8%), 45° herringbone (~13%, the ICPI-required orientation for driveways — it locks against turning tires), and decorative basketweave.

Why pavers need edge restraint — the perimeter creeps and unravels without it
Edge restraint is the #1 thing that keeps pavers tight: without it the perimeter creeps out, joints open, and sand washes away. Spike the restraint to the compacted base (not the soil), tight to the outside course.

Three-coat stucco wall assembly — sheathing, WRB, lath, scratch, brown, finish (7/8″)
Three-coat stucco over framing is a 7/8″ system: two layers of WRB, then metal lath (cups out so the plaster keys behind it), then a 3/8″ scratch coat, 3/8″ brown coat, and 1/8″ finish coat.

Stucco weep screed & ground clearance — WRB laps the flange, ≥4″ above grade
Stucco ends at a weep screed, not at the ground: the WRB laps over its flange, the lath stops on it, and weep holes drain the wall — kept ≥4″ above earth (2″ above paved) so it can’t wick water into the framing.

Stucco control joints — break the wall into ≤144 sq ft panels so it doesn’t crack
Cement stucco shrinks as it cures. Control joints break the wall into panels ≤144 sq ft (≤18 ft any dimension, ≤2.5:1) so the shrinkage relieves at the joints instead of cracking the field randomly.

Asphalt driveway layer stack — subgrade, aggregate base, and HMA courses in cross-section
A driveway is a layer stack, not a slab: compacted subgrade → ~6″ crushed-stone base → tack coat → 2.5–3″ of hot-mix asphalt. The base carries the load — NAPA rates 1″ of HMA ≈ 3″ of aggregate base.

Asphalt driveway drainage — a cross-slope sheds water while a flat driveway ponds and fails
Drainage is the #1 failure mode: a flat driveway ponds water that soaks and ruins the base, while a ~2% cross-slope (plus ≥1% longitudinal grade) sheds it. No ponding, ever.

Compacted vs loose asphalt — place compacted depth, order loose tons
Run tonnage on the COMPACTED depth, then bump the order for loose delivery: HMA ×1.10–1.15, aggregate base ×1.15–1.25 (4″ compacted base ≈ 4.6″ loose). Never compute tons from the loose depth.

Which sand for which job — concrete, fill, mason, and play sand, and whether each compacts
The name on the ticket decides the job. Concrete/sharp (C33) and fill sand are well-graded — they lock under a tamper and carry load (concrete, paver bedding, structural fill). Mason (C144) and play sand are uniform fine grading — they stay loose (mortar, joints, sandboxes). Never use a non-compacting fine sand as a structural paver base; that needs crushed stone.

Sand cubic yards, tons & bags — area × depth ÷ 324, ~1.35 tons and 54 bags per cubic yard
Volume: cubic yards = area(ft²) × depth(in) ÷ 324 (324 = 12 in/ft × 27 ft³/yd³). Then the format — bulk sells by weight and volume: at ~2,700 lb/yd³, 1 yd³ ≈ 1.35 tons; bags are 0.5 ft³ each, so 1 yd³ = 54 bags. Coverage is volume ÷ depth, so deeper covers less (324 ft² at 1″ down to 81 ft² at 4″). Wet sand runs 15–25% heavier.

Paver bedding sand — screed a uniform 1″ over a compacted base, never level the base with sand
Sand is a setting bed, not a fill. Leveling a low base with 2–3″ of sand (left) lets the bed consolidate unevenly, so pavers rut and pond water. The fix (right): compact the aggregate base to grade first, then screed a constant 1″ of ASTM C33 bedding sand (ICPI Tech Spec 2). Fix the grade in the base, not the sand.
Frequently Asked Questions
How many bricks do I need per square foot of wall?
Standard modular brick with a ⅜-inch mortar joint runs about 6.75 to 7 per square foot in running bond; queen and king sizes run fewer. Add 5 to 10 percent for cuts and breakage. The brick calculator pairs the unit count with mortar bags — roughly one 70 lb bag per 40 bricks — so the two quantities arrive together.
How deep should the base be under pavers?
ICPI guidance: 4 to 6 inches of compacted crushed stone for walkways and patios, 8 to 12 for driveways, always compacted in lifts of 2 to 4 inches, topped by exactly 1 inch of bedding sand. Skimping the base is the root cause of nearly every rutted or heaved paver surface. The paver calculator sizes base tonnage from your traffic type.
How thick should each stucco coat be?
The traditional three-coat system over lath runs ⅜-inch scratch coat, ⅜-inch brown coat, and a ⅛-inch finish — about ⅞ inch total per ASTM C926. Each coat has its own cure window before the next. The stucco calculator figures bags per coat separately, because the scratch and brown coats consume most of the material.
How many tons of asphalt do I need for a driveway?
Area × compacted depth × about 145 lb per cubic foot, converted to tons — a 12×50 driveway at 3 inches compacted needs roughly 11 tons, plus the aggregate base beneath it. Hot mix is also sold against a minimum load, so small jobs price differently. The asphalt driveway calculator runs both the asphalt and base tonnage.
What kind of sand goes under pavers?
Concrete sand (ASTM C33) for the 1-inch bedding layer — its angular grains lock under compaction. Mason sand is too fine and holds water; play sand is worse. Joint filling afterward is a different product again (polymeric or fine joint sand). The sand calculator converts bedding area to tons and flags the bag-versus-bulk crossover.
