Patio pavers go down in layers, and the base matters more than the pavers themselves
Patio pavers are installed by digging out the area, laying a compacted gravel base, adding sand, setting the pavers level, and filling the joints with sand or polymeric sand. The work is physical but straightforward — most people can do it without special tools, though a plate compactor (which you can rent) saves your back and produces a better result. The entire process takes a weekend for a small patio, longer for larger areas.
The most common mistake is skipping or rushing the base. Pavers that sit on loose soil or thin gravel will shift, crack, and create puddles within a year. A proper base — 4 inches of compacted gravel — is what keeps pavers flat and drains water away from your house.
Key Takeaways
- Dig out 5 to 6 inches of soil, then add 4 inches of compacted gravel and 1 inch of sand before laying pavers.
- Rent a plate compactor to compress the gravel and sand; hand tamping works but takes much longer and compacts unevenly.
- Lay pavers in a pattern (running bond, herringbone, or straightforward grid), check level frequently, and adjust sand underneath as you go.
- Fill joints with polymeric sand (which hardens when wet) or regular sand, and sweep the surface clean when finished.
- The entire job requires a shovel, level, rubber mallet, and a broom — plus a rented compactor if your patio is larger than 100 square feet.
Measure the area and mark the edges
Measure the length and width of the space where your patio will go. Mark the edges with chalk, spray paint, or string pulled tight between stakes. Include any slope you want — a gentle slope (about 1 inch drop per 8 feet) moves water away from your house and prevents pooling.
Check the marked area for obstacles: tree roots, utility lines, or existing concrete. Call 811 before you dig if you are not certain where gas, electric, or water lines run. Remove any grass or weeds from the marked area with a shovel or sod cutter.
Dig out the base and compact the gravel
Dig down 5 to 6 inches across the entire marked area. The depth accounts for 4 inches of gravel, 1 inch of sand, and the thickness of the paver itself (usually 2 to 2.5 inches). Keep the bottom of the hole as level as possible — use a long straight board and a level to check as you dig.
Spread 4 inches of crushed gravel (also called crushed stone or road base) evenly across the hole. Compact it with a plate compactor, making two or three passes over the entire surface. If you do not have a compactor, rent one from a tool rental shop for about $40 to $60 per day — it will save you hours of hand tamping and produce a much firmer base. The gravel should feel solid underfoot and not shift when you walk on it.
Check the slope as you compact. If you marked a slope, the gravel should follow that same angle. Use a level on a long board to verify.
Add sand and level it
Spread 1 inch of coarse sand (also called concrete sand or paver sand) evenly over the compacted gravel. Do not compact the sand — you will adjust it as you place each paver. Rake it smooth and level, using a long straight board to check that the surface is even and follows your marked slope.
The sand layer is what lets you fine-tune the height of each paver. If a paver sits too high, you remove a little sand. If it sits too low, you add sand underneath. This is why the sand must be loose at this stage.
Lay the pavers in your chosen pattern
Start at one corner and lay pavers in your chosen pattern. Common patterns are running bond (like bricks in a wall), herringbone (diagonal V-shapes), or a straightforward grid. Lay pavers without mortar — they sit on the sand and are held in place by the sand and the joints between them.
As you place each paver, tap it gently with a rubber mallet to set it into the sand. Check the level constantly — place a level across two or three pavers to make sure they are even with each other. If a paver is too high, tap it down harder. If it is too low, lift it out, add a pinch of sand underneath, and reset it.
Work in rows or sections, not randomly. This keeps the pattern straight and makes it easier to spot pavers that are out of line. Leave a gap of about 1/8 inch to 1/4 inch between pavers — this is where the joint sand goes and allows for slight expansion in heat.
Fill the joints and finish
Once all pavers are set and level, fill the joints with sand. Polymeric sand is the better choice — it hardens when wet and resists weeds and ants better than regular sand. Spread it across the surface with a broom, sweeping it into the gaps between pavers. Sweep off the excess so the surface is clean.
If you used polymeric sand, mist the surface lightly with a garden hose to set up it. Do not soak it — just enough water to dampen the sand. Let it cure for 24 to 48 hours before walking on it heavily. If you used regular sand, you may need to add more after the first rain, as some will wash away.
Check the patio after a few weeks. If any pavers have shifted or settled unevenly, you can lift them out and add or remove sand to reset them level.

Frequently Asked Questions
Do I need to use polymeric sand or can I just use regular sand?
Regular sand works and costs less, but it washes away in rain and allows weeds to grow between pavers. Polymeric sand hardens when wet and lasts longer. For a patio you want to stay neat, polymeric sand is worth the extra cost.
What if my patio area is not level to begin with?
Dig deeper in the high spots and shallower in the low spots so the bottom of the hole is as level as possible. Then follow the slope you marked when you compact the gravel. The pavers will follow that slope and water will drain correctly.
Can I lay pavers on top of existing concrete?
Yes, but the concrete must be clean, level, and in good condition. Sweep it thoroughly, fill any cracks with concrete filler, and lay pavers directly on the concrete with polymeric sand in the joints. You skip the gravel and sand base entirely. This works for small patios but is less stable than a proper gravel base for large areas.
How long do patio pavers last?
Pavers themselves last 25 years or more if they are made from concrete or stone. The joints and base may need maintenance sooner — reapply polymeric sand every few years and check the base for settling. A well-built patio with a solid gravel base will stay level and usable for decades.
What should I do if pavers crack or break?
Remove the damaged paver by lifting it out carefully, replace it with a new one of the same size and style, and refill the joints with sand. This is one advantage of pavers over poured concrete — individual pieces can be swapped without affecting the rest of the patio.
