Start with a solid base and proper drainage
A paver patio lasts longer and stays level when you build on compacted soil and a gravel base, not directly on dirt. The ground shifts with frost and rain, and without a foundation layer, your pavers will crack, sink, or tilt within a year or two.
Dig out the area to a depth of 4 to 6 inches, depending on your climate — colder regions need deeper bases because frost heave pushes pavers up. Remove grass, roots, and rocks larger than a pebble. Compact the soil firmly with a hand tamper or plate compactor (you can rent one). Then add 4 inches of crushed stone or gravel, compact that too, and finish with 1 inch of sand. The sand is what you'll set the pavers into; it lets you adjust height and keeps them from rocking.
Key Takeaways
- Dig 4 to 6 inches deep, compact the soil, add 4 inches of gravel, then 1 inch of sand — this base prevents sinking and cracking.
- Lay out pavers dry first to check the pattern and see where you'll need to cut; mark cut lines with chalk before you wet the sand.
- Set each paver by tapping it level with a rubber mallet, checking constantly with a level so the patio slopes slightly for water runoff.
- Fill the gaps between pavers with polymeric sand, which hardens when wet and locks the pavers in place without washing out.
- Rent a plate compactor at the end to settle everything and lock the sand into the joints.
Measure, mark, and lay out pavers before you set them
Measure the length and width of your patio area and mark the edges with string or chalk. Lay pavers out dry on the sand — don't set them yet — to see how they fit and where cuts will fall. Most people arrange pavers in a running bond (like bricks), a herringbone, or a straightforward grid. Running bond uses less cutting; herringbone looks better but wastes more material.
Mark any pavers that need cutting with chalk on the top. A wet saw with a diamond blade cuts pavers cleanly; a circular saw with a masonry blade works too but is dustier. Cut from the back side if you can, and wear a dust mask — paver dust contains silica, which damages lungs. Once you're happy with the layout, you're ready to set them in the sand.
Set pavers level and sloped for drainage
Start at one corner and work across. Place each paver on the sand, tap it down with a rubber mallet, and check it with a level. The patio should slope very slightly — about 1/8 inch per foot — so water runs off instead of pooling. You can achieve this by making the sand base slightly thicker on one side, or by tapping pavers lower on the downhill side.
Check every few pavers with a level and adjust by adding or removing sand underneath. If a paver sits too high, tap it down; if it's too low, lift it, add sand, and reset it. This takes patience, but it's the difference between a patio that drains and one that becomes a mosquito breeding ground. Keep checking as you go — it's much easier to fix one paver than to reset twenty.
Cut pavers at edges and around obstacles
Pavers at the edges of your patio will need cutting to fit the space. Mark the cut line on the paver with chalk, then use a wet saw to cut straight across. If you're cutting around a tree or post, measure twice and mark the outline on the paver before cutting. Some cuts are easier to make with a paver splitter — a hand tool that breaks pavers along a scored line — but a wet saw gives you more control.
Wear safety glasses and a dust mask when cutting. Wet the blade and the paver to keep dust down. Work slowly; rushing causes the blade to bind and kick back. If you're cutting many pavers, rent a wet saw for the day rather than buying one — the cost is usually $40 to $60.
Fill joints with polymeric sand to lock pavers in place
Once all pavers are set and level, fill the gaps between them with polymeric sand. This is regular sand mixed with a binder that hardens when it gets wet. Sweep the sand across the patio so it fills all the joints, then use a broom to work it down into the gaps. Brush off the excess from the top of the pavers.
Lightly mist the patio with a garden hose — don't soak it, just dampen the sand. The polymeric sand will harden over the next 24 hours. Don't let anyone walk on it during that time. Once it's set, the pavers are locked together and won't shift or let weeds grow between them. Polymeric sand costs more than regular sand but lasts much longer and requires less maintenance.
Compact the finished patio to settle everything
After the polymeric sand has cured for a full day, rent a plate compactor and run it over the entire patio. This settles the pavers into the sand base and compacts the sand in the joints. Make two or three passes, overlapping each pass slightly. The compactor will vibrate the pavers and make sure they're all sitting firmly.
Check the patio one more time with a level after compacting. If any pavers have shifted or settled unevenly, you can tap them back into place with the mallet. A plate compactor costs $40 to $80 per day to rent and is worth the money — it's the difference between a patio that stays solid for years and one that develops soft spots and uneven surfaces.
Maintain your patio to extend its life
Sweep your patio regularly to keep dirt and leaves from accumulating. Every year or two, check the joints for gaps where the polymeric sand has worn away, and refill them. If weeds grow between pavers despite the polymeric sand, pull them by hand or spray them with a weed killer that won't harm the pavers.
Seal the pavers every two to three years with a paver sealer. This protects them from stains, fading, and water damage, and makes them easier to clean. Most sealers are applied with a roller or sprayer and dry in a few hours. Avoid pressure washing, which can force water under the pavers and damage the base — use a broom and mild soap instead.
Frequently Asked Questions
Do I need to remove grass before laying pavers?
Yes. Grass and roots underneath will decompose and create voids, causing pavers to sink. Dig out all vegetation, then compact the bare soil before adding gravel and sand. If you leave grass, your patio will be uneven within a season.
Can I lay pavers directly on concrete?
You can, but it's not ideal. Concrete doesn't drain, so water pools underneath and can damage the pavers. If you must use concrete, add a layer of sand on top and slope it for drainage. A new base of soil, gravel, and sand is better if you have the time.
What's the difference between polymeric sand and regular sand?
Regular sand washes out between pavers when it rains, leaving gaps where weeds grow. Polymeric sand hardens when wet and stays in place. It costs more upfront but saves you maintenance work and keeps your patio looking neat for years.
How long does it take to build a paver patio?
A small patio (10 by 12 feet) takes a weekend if you work alone. Larger patios take longer. Most of the time goes to digging, compacting, and setting pavers level — the actual laying is fast once the base is done. Plan for two to three days if you're doing it yourself.
Can I install pavers in winter?
Not in freezing climates. Frost will heave the pavers and crack the base. Install pavers in spring, summer, or early fall when the ground is not frozen. In mild climates, winter installation is fine as long as the ground isn't wet or muddy.
