You can lay a brick patio yourself if you have a level yard and are willing to spend a weekend on preparation

A brick patio is one of the most forgiving outdoor projects for a homeowner without experience. Unlike roofing or plumbing, mistakes are visible but fixable—you can pull up a brick, adjust the sand underneath, and reset it. The work is physical rather than technical: digging, leveling, laying bricks in a pattern, and sweeping sand into the joints. Most small patios (10 by 12 feet or smaller) take a weekend or two. Larger ones take longer, but the method stays the same.

The real constraint is not skill but patience with the ground. A brick patio will shift and crack if the base is not level and compact. This is where most DIY patios fail—not in the brick-laying, but in rushing the foundation. If you are willing to spend a full day on the base layer, the rest is straightforward.

Key Takeaways

  • The base layer—compacted gravel and sand—determines whether your patio stays level or cracks within a year, so do not skip this step.
  • You need a shovel, a level, a rubber mallet, a wheelbarrow, and a hand tamper; a power compactor rents for $40 to $60 per day and saves your back.
  • Brick patterns like running bond (offset rows) and herringbone look professional but take longer than a straightforward grid.
  • Polymeric sand (which hardens when wet) costs more than regular sand but keeps weeds out and requires less maintenance over time.
  • A patio larger than 12 by 16 feet or on a slope should have a professional check the drainage plan before you dig.

What you need before you start digging

Gather your tools and materials in one place. You will need a shovel, a wheelbarrow, a level (a 4-foot one is standard), a rubber mallet, a hand tamper or power compactor, a tape measure, and a string line. For the patio itself: bricks (order 5 percent extra for breakage and cuts), landscape fabric, gravel (usually 4 inches deep), coarse sand (2 inches), and either regular sand or polymeric sand for the joints.

Before you buy anything, mark out the patio area with spray paint or chalk. Measure twice. Walk the space and look for low spots—these will collect water and cause problems later. If the yard slopes noticeably, you may need to build a small retaining edge or adjust the patio height. A slope of 1 inch per 8 feet is acceptable and actually helps water drain; anything steeper than that and you should have a professional review your plan.

Check for underground utilities. Call 811 or your local utility locating service (usually free) and have them mark gas, electric, and water lines. Do this before you dig. It takes a few days, so plan ahead.

Preparing the ground: the foundation that holds everything

Dig out the area to a depth of 6 to 7 inches. This leaves room for 4 inches of gravel, 2 inches of sand, and 1 inch for the brick itself. Use a shovel and a level as you go—the bottom of the hole should be as level as possible. This is tedious work, but it is the most important part. A low spot in the base will become a puddle and a weak point.

Lay landscape fabric on the bottom. This prevents weeds from growing up through the patio and keeps gravel from sinking into soft soil. Overlap the edges by 6 inches.

Spread 4 inches of gravel (crushed stone, not pea gravel) and compact it firmly. A hand tamper works for small patios; a power compactor (which you can rent) is much faster for anything larger. Compact in overlapping passes until the gravel no longer shifts under your foot. This is where most people cut corners, and it is where patios fail. Spend the time.

Spread 2 inches of coarse sand on top of the gravel and level it. Use a straight board (a 2-by-4 works well) laid across the edges to screed the sand flat. The sand is your final leveling layer—small adjustments here prevent rocking bricks later.

Laying the bricks in a pattern

Start at one corner and work outward. The simplest pattern is a grid (bricks in straight rows), which takes the least time. Running bond (offset rows, like a brick wall) looks more finished and is only slightly slower. Herringbone (bricks at 45 degrees in a zigzag) looks professional but requires more cuts and takes longer.

Lay the first row without mortar, using the sand as your bed. Tap each brick with a rubber mallet to settle it into the sand. Use a level frequently—check both along the row and across the width of the patio. Bricks should sit firmly and not rock. If one is high, tap it down; if it is low, pull it up, add a pinch of sand underneath, and reset it.

Continue row by row, checking level as you go. If you are using a pattern that requires cuts (like herringbone), mark the bricks with a pencil and cut them with a circular saw fitted with a masonry blade, or rent a wet saw from a tool rental shop. Wet saws are cleaner and faster but cost $40 to $80 per day. Wear a dust mask when cutting.

Leave a 1/8-inch gap between bricks for the sand joints. This is small enough that it looks intentional, not sloppy. A spacer made from a thin piece of wood helps keep gaps even.

Filling the joints and sealing the edges

Once all the bricks are laid, spread sand (regular or polymeric) across the surface and sweep it into the joints with a stiff broom. Work diagonally across the bricks so you do not push sand out of the joints. Make multiple passes until the joints are full and level with the brick surface.

If you used polymeric sand, mist the patio lightly with a garden hose. The sand will harden as it dries (follow the product instructions for timing—usually 24 to 48 hours). Do not walk on it during this time. Regular sand will not harden; it will settle and may need topping up after rain or a season or two.

For the edges, you have two choices: leave the bricks as they are (clean and straightforward), or install a metal or plastic edge restraint. Edge restraints keep bricks from shifting outward and look finished. They bolt or stake into the ground along the perimeter.

Finishing touches and long-term care

Once the sand has set, your patio is ready to use. Sweep it clean and let it settle for a few days before moving heavy furniture onto it.

Over time, sand will wash out of the joints, especially in the first year. Sweep new sand in as needed. If weeds grow through, pull them or spray them with a weed killer (polymeric sand reduces this problem significantly). In cold climates, freeze-thaw cycles can shift bricks—reset them in spring if needed.

A brick patio does not need sealing, but sealing can darken the color and make it easier to clean. Sealers wear off over time and need reapplication every few years. It is optional.

When to call a professional instead

If your yard has poor drainage, slopes more than 1 inch per 8 feet, or sits in a low spot where water collects, have a landscape professional assess the site before you start. They can recommend grading changes or a drainage system that prevents water damage.

If you are laying a patio larger than 16 by 20 feet, consider hiring help for the base work. The digging and compacting are the hardest parts physically, and a second person makes it faster and more accurate.

If you hit rock or very hard clay while digging, stop and reassess. You may need to rent a jackhammer or hire an excavator. Trying to dig through rock with a shovel will exhaust you and damage your tools.

Frequently Asked Questions

Can I lay a brick patio on top of existing concrete?

Yes, if the concrete is in good condition and level. Lay landscape fabric on top, then 1 to 2 inches of sand, then the bricks. The concrete acts as your base layer. If the concrete is cracked or uneven, the bricks will follow those flaws, so repair or replace the concrete first.

How much does a brick patio cost?

Costs vary by brick type and size. Standard clay bricks run $0.50 to $1.50 each; decorative or reclaimed bricks cost more. A 10-by-12-foot patio (120 square feet) needs roughly 480 bricks, plus gravel, sand, and tools. Budget $500 to $1,500 depending on brick choice and whether you rent a power compactor.

What if I lay the bricks and they start to shift?

Shifting usually means the base was not compacted enough or water is pooling underneath. Pull up the shifting bricks, check the sand and gravel underneath for settling or moisture, recompact if needed, and reset the bricks. Add edge restraints if bricks are moving outward.

Do I need to use mortar between the bricks?

No. Sand joints are standard for patios and are easier to maintain than mortar. Mortar cracks in freeze-thaw cycles and is harder to repair. Sand is the right choice for a DIY patio.

How long does a brick patio last?

A well-built brick patio lasts 20 to 30 years or longer. The bricks themselves are durable; the limiting factor is the base. If the base settles unevenly or water pools underneath, the patio will crack and shift. Proper compaction and drainage add decades to the life of the patio.
