A brick patio takes two to four weekends and costs between $800 and $2,500 depending on size and brick choice

Building a brick patio yourself means laying a foundation, setting up a border, and placing bricks in a pattern over sand and gravel. The work is physical but straightforward — you do not need special tools beyond a rubber mallet, a level, and a wheelbarrow. Most homeowners can complete a 12-by-12-foot patio in three weekends if the ground is reasonably level and you work alone or with one helper.

The real variable is site preparation. If your ground is compacted clay or slopes badly, you will spend more time and money on grading and drainage. If it is already level and well-draining, you can move faster. Either way, the steps are the same: mark the area, remove sod and topsoil, build a border, lay the base, and set the bricks.

Key Takeaways

  • Brick patios need a 4-inch gravel base and 1 inch of sand on top, compacted in layers, or the bricks will shift and puddle within a year.
  • A border of treated wood or plastic edging holds the bricks in place and keeps them from spreading outward as you walk on them.
  • Running bond and herringbone are the most common patterns; running bond is faster and uses less cutting, while herringbone looks formal but wastes more brick.
  • Slope the finished patio away from your house at a rate of 1 inch per 8 feet so water drains and does not pool against your foundation.
  • Polymeric sand locks bricks together and resists weeds better than regular sand, though it costs more and requires dry conditions to set.

Measure the space and mark the perimeter

Measure the length and width of where you want the patio. Mark the corners with wooden stakes and string. Check that the corners are square by measuring diagonally from corner to corner — both diagonals should be equal. If they are not, adjust the stakes until they are.

Mark the perimeter by spraying chalk or flour along the string line. Remove the stakes and string once the outline is clear. This outline is where you will dig.

Remove sod and topsoil to the right depth

Dig out the sod and topsoil inside the marked area to a depth of 5 to 6 inches. This depth accounts for 4 inches of gravel base, 1 inch of sand, and the thickness of the brick itself (usually 2.25 inches). You want the finished patio to sit level with or slightly above the surrounding ground so water does not collect on it.

Pile the removed soil to the side — you can use it to fill low spots elsewhere in the yard. Compact the exposed soil with a hand tamper or a rented plate compactor. The base must be firm or the bricks will settle unevenly over time.

Check the slope as you work. The patio should drop about 1 inch in elevation for every 8 feet of length, sloping away from your house. Use a 4-foot level and a shim to measure this. Place the level on the ground, put a shim under one end, and adjust until the bubble is centered — the shim height tells you the slope.

Install the border and lay the gravel base

Set treated wood boards or plastic edging around the perimeter of the dug area. The border should sit at the height you want the finished patio to be. find wood borders with stakes driven into the ground on the outside. Plastic edging usually clips to stakes. The border prevents bricks from spreading outward and gives you a straight edge to work against.

Pour 4 inches of gravel (crushed stone, not pea gravel) into the bordered area. Spread it evenly and compact it with a plate compactor or hand tamper. Compact in two passes — 2 inches, then another 2 inches — rather than all at once. A loose base will cause the patio to settle and crack.

Check the slope again as you compact. The gravel surface should still slope away from your house at the same 1-inch-per-8-feet rate.

Spread sand and set the first row of bricks

Pour 1 inch of coarse sand over the compacted gravel. Do not compact the sand — you want it loose so you can adjust brick height as you lay them. Spread it evenly with a rake or shovel.

Lay the first row of bricks along one edge, usually the edge closest to your house or the longest straight side. Place bricks end to end with no gap between them. Use a rubber mallet to tap each brick down until it sits level with its neighbors. Check frequently with a 4-foot level. Bricks that are too high or too low will create trip hazards and uneven water drainage.

If a brick sits too high, tap it down with the mallet. If it sits too low, lift it out, add a pinch of sand underneath, and reset it. This takes patience but saves time later — a crooked first row throws off every row that follows.

Lay the remaining bricks in your chosen pattern

The two most common patterns are running bond and herringbone. Running bond is bricks laid end to end in offset rows, like a brick wall — each row starts halfway across the brick below it. Herringbone is bricks laid at 45-degree angles in a V-shaped pattern. Running bond is faster and wastes less brick. Herringbone looks more formal but requires more cutting at the edges.

Lay each brick snug against the ones beside it. Use the mallet to tap bricks down so they sit level with their neighbors. Check the overall slope every few rows with a long level. The patio should still slope away from your house.

At the edges, you will need to cut bricks to fit. Mark the brick with a pencil, then use a brick chisel and hammer to split it along the line. Wear safety glasses — brick chips fly. Alternatively, rent a wet saw from a tool rental shop for $30 to $50 per day if you have many cuts to make.

Fill joints and seal if desired

Once all bricks are laid, sweep sand into the joints between them. Sweep in multiple directions so sand fills the gaps completely. Spray the patio lightly with a hose — the water helps settle the sand. Sweep more sand into any gaps that open up as the sand settles.

Regular sand works but weeds will grow through it over time. Polymeric sand costs more ($15 to $30 per bag versus $3 to $5 for regular sand) but hardens when wet and resists weeds. If you use polymeric sand, follow the manufacturer's instructions — most require the patio to be completely dry before process and for 24 to 48 hours after.

Sealing the bricks is optional. A sealer protects against stains and weathering but requires reapplication every two to three years. If you skip sealing, the bricks will weather to a natural gray over time but will remain structurally sound.

Frequently Asked Questions

Can I build a brick patio on top of concrete?

Yes. Clean the concrete, fill any cracks with concrete filler, and lay 1 inch of sand directly on top. Skip the gravel layer since the concrete already provides a stable base. The concrete must slope away from your house or water will pool underneath the bricks.

What is the difference between clay brick and concrete brick?

Clay brick is fired in a kiln and comes in warm reds and browns. Concrete brick is cast and comes in grays and tans. Clay is more durable and weathers beautifully but costs more ($1 to $2 per brick versus $0.50 to $1 for concrete). Both work for patios; choose based on appearance and budget.

How do I fix bricks that have settled or cracked?

Remove the affected bricks, add or remove sand underneath, and reset them. If a brick is cracked, replace it. Settled bricks usually mean the base was not compacted enough — if many bricks settle, you may need to remove a section, recompact the base, and relay the bricks.

Do I need to remove the border after the patio is done?

No. The border stays in place permanently. It holds the bricks together and prevents them from spreading. If you used wood, it will eventually rot — replace it every five to ten years or use plastic edging from the start.

What should I do if the ground is very uneven or slopes toward my house?

Grade the area first. Remove high spots and fill low spots with soil, then compact. If the slope is steep, you may need to build a retaining wall or create steps instead of a single flat patio. Consult a local landscaper if the grade change is more than 12 inches.
