Concrete Aggregates

Concrete aggregates are the backbone of durable, workable mixes for slabs, footings, driveways, paths, and masonry. This collection spans washed concrete sand, gravel, crushed stone, pea gravel, recycled concrete aggregate (RCA), and lightweight expanded aggregates—helping you achieve target strength, finish quality, and drainage while controlling cost.

Choose the right size and shape for performance:
- 3/4 in (19 mm) crushed stone: reliable for structural slabs, footings, and foundations; angular faces lock up for strength.
- 3/8 in (10 mm) gravel/stone: ideal for thin sections, countertops, overlays, and pumped mixes; improves flow and finish.
- Pea gravel: smooth, rounded aggregate for exposed aggregate finishes, patios, and decorative concrete.
- Concrete sand (coarse, washed): optimizes workability and reduces water demand; preferred over masonry sand for mixes.

Quality matters. Look for washed, graded materials that meet ASTM C33 or EN 12620 to minimize fines, improve bond, and reduce shrinkage and cracking. Consistent gradation boosts pumpability and finish while supporting air entrainment in freeze–thaw climates. For sustainability and cost control, consider locally sourced stone or RCA to lower transport emissions and support green building goals.

Actionable tips to get great results:
- Match aggregate size to reinforcement spacing and slab thickness.
- Account for moisture—damp aggregate changes water–cement ratios; adjust mix water or pre-wet for consistency.
- Keep stockpiles clean, covered, and separated to prevent contamination and variability.
- Request mill certificates and gradation reports to verify compliance.
- Order a buffer (5–10%) to cover waste and compaction.

Ordering is easy with options for bulk delivery, dump loads, and forkliftable bulk bags for tight sites. Use coverage calculators and unit weights to estimate yardage for pads, footings, and sub-bases. For site safety, manage dust with wetting, wear respiratory protection around silica, and plan access for trucks. Whether you’re pouring a driveway, forming a slab, or topping a patio, quality concrete aggregates lay the foundation for strong, long‑lasting results.
