Brick Patio on Sand: Base, Bricks, and Steps
A brick patio on sand is a classic dry-laid patio: bricks set on a screeded layer of sand over a compacted gravel base, held by firm edging, with sand swept into the joints. Despite the name, the sand is only a thin bedding layer; the gravel base underneath does the structural work. Use paving brick rated for outdoor ground contact, not ordinary building brick, which can crack and flake in freeze-thaw weather.
Volume and tonnage calculator →Paving brick vs building brick
| Brick | Use |
|---|---|
| Paving brick (clay pavers) | Patios, walks, driveways |
| Building or face brick | Walls; may spall on the ground |
| Concrete brick-style pavers | Patios; often thicker |
| Reclaimed brick | Charming but may not resist freezing |
Paving brick meets standards for abrasion and freeze-thaw resistance. Ask the supplier for brick rated for pedestrian or vehicle paving.
Layers
| Layer | Depth |
|---|---|
| Compacted gravel base | 4 to 6 in |
| Bedding sand | About 1 in |
| Brick | About 2 1/4 in on flat |
See how deep should paver base be.
Step by step
- Lay out and excavate to base plus sand plus brick depth.
- Slope about 1/8 to 1/4 inch per foot away from buildings.
- Compact the soil and add fabric on soft ground.
- Add base in lifts, compacting each.
- Install edging on the base. See paver edge restraint.
- Screed sand to 1 inch using pipes as guides.
- Lay bricks in your pattern, tight together.
- Compact with a plate compactor and a protective pad.
- Sweep sand into joints and repeat until full.
Patterns
| Pattern | Notes |
|---|---|
| Running bond | Simple, few cuts |
| Basket weave | Classic; works with 4x8 brick |
| Herringbone | Strongest interlock; more cuts |
| Stack bond | Modern look; weaker interlock |
Herringbone at 45 or 90 degrees is best for areas with heavy use.
How many bricks
Standard 4x8 paving brick laid flat needs 4.5 per square foot. A 12x14 patio of 168 square feet needs about 756 bricks, plus 5 to 15 percent depending on pattern. See how many bricks per square foot.
Joint sand
Use fine masonry sand or polymeric sand. Polymeric sand hardens and resists weeds and ants. See how much sand for pavers.
Maintenance
Top up joint sand as needed, pull weeds early, and reset any settled bricks by lifting them and adding sand.
Cutting brick
Edges and curves need cut bricks. A wet masonry saw gives clean cuts and is worth renting for a patio with a border or herringbone pattern. A brick chisel and hammer work for a few rough cuts. Wear eye and hearing protection, and a respirator when dry cutting, since brick dust contains silica.
Bottom line
A brick patio on sand needs a 4 to 6 inch compacted gravel base, about 1 inch of bedding sand, paving-grade brick, firm edging, and filled joints. Choose herringbone for strength, and use the asphalt base calculator to estimate base tons.
