Start with a level base and proper drainage
A paver patio lasts longer and stays level when you build it on compacted soil and a sand base, not directly on dirt. The ground shifts and settles unevenly over time, which cracks pavers and creates puddles. You need to dig out the top 4 to 6 inches of soil, compact it firmly, add 1 inch of landscape fabric to block weeds, then lay down 1 to 2 inches of coarse sand and compact that too.
Drainage matters more than most first-time builders expect. Water that pools under pavers freezes in winter and heaves them upward. Slope your patio slightly—about 1/8 inch per foot of length—so water runs off to one side. If your yard is already flat or slopes the wrong way, you may need to dig deeper on one end or add a shallow drainage trench along the downhill edge.
Key Takeaways
- Dig 4 to 6 inches deep, compact the soil, add landscape fabric, then lay 1 to 2 inches of compacted sand before setting any pavers.
- Slope the patio 1/8 inch per foot so water runs off instead of pooling and freezing under the pavers.
- Lay pavers in a straight line using a level and rubber mallet, checking every few rows to keep them flush with each other.
- Fill the gaps between pavers with polymeric sand, which hardens when wet and locks the pavers in place.
- Rent a plate compactor for the final step—it settles everything and prevents pavers from shifting under foot traffic.
Measure, mark, and plan your layout before digging
Sketch your patio on paper with rough dimensions, then mark the actual corners with stakes and string. Walk around the marked area to make sure the size and shape feel right in your yard. A 12-by-16-foot patio is large enough for a table and chairs; smaller than 10 feet in any direction feels cramped for furniture.
Decide on your paver pattern before you buy materials. A running bond (offset rows, like bricks) hides imperfections better than a grid pattern and uses fewer cut pavers at the edges. Lay out a few rows on the sand without mortar first—this is called a dry run—so you can see where cuts fall and adjust the starting line if needed. Many builders shift the first row by half a paver width to avoid ending with a sliver on the far edge.
Dig and prepare the base in the right order
Mark your digging depth with a stake at each corner. Most patios need 4 to 6 inches of excavation depending on your paver thickness (usually 2 to 2.5 inches) plus sand and base materials. Use a shovel for small areas under 100 square feet, or rent a small excavator for anything larger—it saves your back and takes hours instead of days.
Once you have dug to depth, tamp the soil with a hand tamper or rent a plate compactor. The soil should feel solid underfoot and not shift when you step on it. Lay landscape fabric over the entire area to block weeds from growing up between pavers. Then spread coarse sand (not play sand, which is too fine) in a 1 to 2-inch layer and compact it again. The sand should be damp but not soaking wet when you compact it—this helps it settle evenly.
Set pavers in rows, checking level constantly
Start at one corner and lay the first paver on the sand. Tap it down gently with a rubber mallet until it sits level with your string line. Use a 2-foot level across every paver and between adjacent pavers to catch high or low spots before you move forward. If a paver sits too high, tap it down; if it sits too low, lift it, add a pinch of sand underneath, and reset it.
Work in rows across the patio, not in a scattered pattern. Lay each paver tight against the last one—the gap should be about 1/8 inch, which happens naturally when pavers are cut square. Every third or fourth row, check the level along the entire width to catch drift before you have laid too many. A patio that slopes gradually is fine; one that dips in the middle or has a high spot in the corner will look wrong and shed water poorly.
Cut pavers at the edges with a wet saw or a paver splitter (a hand tool that costs $20 to $40 and works for straight cuts). Wear a dust mask when cutting with a wet saw—paver dust contains silica, which damages lungs. Soak the paver in water for 10 minutes before cutting so the blade does not overheat.
Fill joints with polymeric sand to lock pavers in place
Once all pavers are set and level, sweep polymeric sand into the gaps between them. This sand contains a binder that hardens when it gets wet, locking the pavers together so they do not shift under foot traffic. Spread the sand across the entire patio with a broom, working it into every joint. Sweep off the excess so the sand sits just below the paver surface.
Mist the patio lightly with a garden hose—do not spray hard, or you will wash the sand out of the joints. The sand will harden over the next 24 hours. Do not walk on the patio or let rain soak it until the sand has set. If you see sand wash out during rain, let it dry and sweep more in once the weather clears.
Compact the entire patio with a plate compactor
Rent a plate compactor (also called a vibratory compactor) from a tool rental shop for $40 to $80 per day. This machine vibrates and settles the pavers and sand together, preventing them from shifting when someone walks or sits on them. Run the compactor over the entire patio in overlapping passes, moving slowly so the machine has time to work.
The compactor is loud and shakes the ground—wear hearing protection and let neighbors know you are using it. After compacting, sweep the patio clean and inspect for any pavers that have settled unevenly. If one sits noticeably lower than its neighbors, lift it, add sand, and reset it, then run the compactor over that section again.
Seal pavers and maintain the patio
Sealing is optional but extends the life of pavers and makes them easier to clean. Wait 30 days after installation so the polymeric sand has fully cured, then explore a paver sealer with a roller or sprayer. Most sealers darken the color slightly and make pavers look wet. Reapply every 2 to 3 years, or follow the product instructions.
Sweep the patio regularly to prevent dirt and leaves from settling into the joints. If weeds grow between pavers despite the landscape fabric, pull them by hand or spray them with a weed killer made for pavers. Avoid pressure washers on new patios—the force can dislodge pavers that have not fully settled. After a year, the patio will be solid enough to pressure wash if needed.
Frequently Asked Questions
How much does a paver patio cost?
Pavers themselves run $2 to $15 per square foot depending on material and style. Sand, landscape fabric, and polymeric sand add another $1 to $3 per square foot. A 200-square-foot patio (roughly 12 by 16 feet) costs $600 to $3,600 in materials alone. Labor from a contractor typically doubles or triples the total.
Can I build a paver patio on top of concrete?
Yes, but the concrete must be clean, level, and not cracked. Sweep it thoroughly, then lay pavers directly on a thin bed of polymeric sand or paver base. Skip the landscape fabric since water will drain under the concrete anyway. This method is faster than digging but works only if your concrete is already in good shape.
What if my patio settles unevenly after I finish?
Some settling is normal in the first few months. If one paver sinks noticeably lower than others, you can lift it, add sand underneath, and reset it. If the whole patio settles, it usually means the base soil was not compacted enough—this is harder to fix and may require removing sections and rebuilding the base.
Do I need to remove the old patio before building a new one?
If the old patio is concrete or asphalt, you can build over it if it is level and not cracked. If it is old pavers or flagstone, remove it first—the uneven base will cause your new pavers to settle unevenly. Rent a dumpster or haul the old material to a recycling center.
How long does a paver patio last?
Properly installed pavers last 25 to 50 years or longer. The polymeric sand and base materials may need refreshing every 5 to 10 years if weeds or erosion become a problem. Sealing every few years slows color fading and keeps pavers looking new.
