Laying pavers yourself takes three to five days for a typical 12-by-16-foot patio, depending on ground conditions and how many people help. The basic sequence is: prepare and level the ground, lay a sand base, set pavers in a pattern, fill the joints, and compact everything. Most of the work is digging and leveling — the actual paver placement is straightforward once the base is solid.
Key Takeaways
- The ground must be dug out, leveled, and compacted before any sand or pavers go down, or the patio will shift and crack within a year.
- A four-inch base of compacted gravel plus two inches of sand is standard for most residential patios and prevents water from pooling underneath.
- Pavers are laid in a running bond, herringbone, or basket weave pattern — running bond is fastest for beginners and uses the least waste.
- Polymeric sand (which hardens when wet) holds pavers in place better than regular sand and resists weeds, though it costs more and requires careful installation.
- Renting a plate compactor for the base and a hand tamper for the finished surface costs $40 to $80 per day and saves your back.
Prepare and level the ground
Mark out the patio area with stakes and string, then dig out the top four to six inches of soil. Remove grass, roots, and rocks larger than a golf ball. The goal is to expose bare earth that is reasonably level — it does not have to be perfect yet.
Check the level with a four-foot level or a straight board laid across the area. Mark the high and low spots. If the difference is more than two inches across the whole patio, you will need to move soil around — dig from the high spots and fill the low ones. Compact the soil as you go with a hand tamper or a rented plate compactor. Loose soil will settle later and crack your pavers.
Once the soil is level and firm, lay landscape fabric over the entire area. This blocks weeds from growing up through the joints. Overlap the edges by six inches and pin them down with landscape staples.
Add gravel base and sand layer
Spread four inches of compacted gravel (crushed stone, not river rock) evenly over the fabric. Use a rake to spread it, then run the plate compactor over it in overlapping passes until it is firm and does not shift under your foot. This layer drains water away from underneath the pavers and prevents frost heave in cold climates.
Once the gravel is compacted, spread two inches of coarse sand on top. Do not use fine sand or play sand — coarse sand (sometimes labeled "concrete sand" or "paver base sand") locks the pavers in place. Rake it level, then use a straight board laid across the gravel to screed the sand flat. A screed board is straightforward a board long enough to span the width of your patio, dragged across the sand to level it in one pass.
The sand layer does not need compacting before you lay pavers — the weight of the pavers and foot traffic will settle it. If you compact it first, the pavers will sit too high and you will have to add more sand later.
Lay pavers in your chosen pattern
The three most common patterns are running bond (each row offset by half a paver), herringbone (pavers at 45 degrees in a V pattern), and basket weave (alternating direction in a checkerboard). Running bond is fastest and wastes the least material. Herringbone looks more formal but requires more cuts at the edges. Basket weave is in between.
Start at one corner and lay pavers in a dry run first — do not set them yet, just place them on the sand to check the pattern and see where cuts are needed. Mark the pavers that need cutting with chalk. A wet saw with a diamond blade cuts pavers cleanly; most tool rental shops rent them for $30 to $50 per day. Dry cutting with a circular saw and masonry blade works but creates heavy dust — wear a respirator if you go this route.
Once you have cut the edge pavers, lay them in place one row at a time, pressing each paver firmly into the sand. Use a rubber mallet to tap them level — do not drop them or hit them hard. Check every few pavers with a level to make sure the surface is even. If a paver is too high, tap it down; if it is too low, lift it out, add a pinch of sand underneath, and reset it.
Fill joints with sand or polymeric sand
Once all pavers are laid, you have two choices for the joints: regular coarse sand or polymeric sand. Regular sand is cheaper and easier to install — just sweep it across the pavers so it fills the gaps, then spray the whole surface lightly with water to settle it. Sweep and spray again until the joints are full. This takes about an hour for a typical patio.
Polymeric sand costs two to three times more but hardens when it gets wet, locking the pavers together and resisting weeds and ant hills. It requires more care during installation: sweep it into the joints, mist it lightly with water (not a heavy spray), let it set for 24 hours, then mist again. Do not let it dry in clumps or it will harden unevenly. Follow the manufacturer's instructions exactly — different brands have different watering schedules.
If you use regular sand, you will need to top it off every year or two as it settles and washes away. Polymeric sand lasts longer but costs more upfront.
Compact and finish the surface
After the joints are filled and settled, run the plate compactor over the entire patio one more time. This locks everything together and settles the sand into the joints. Make two or three passes in overlapping rows. The pavers should not shift under the compactor — if they do, the base is not solid enough and you need to go back and compact the gravel more.
Sweep the surface clean and let it sit for 24 hours before walking on it heavily. The sand will continue to settle slightly over the next few weeks, so you may need to add more sand to the joints once or twice. This is normal.

Common mistakes that cause problems later
Skipping the gravel base or using only one inch instead of four is the most common mistake. Pavers will sink unevenly, crack, and shift within a year. The gravel is not optional — it drains water and prevents frost heave. If your area freezes in winter, the base is even more critical.
Using fine sand or play sand instead of coarse sand is the second mistake. Fine sand compacts too much and holds water, which causes pavers to shift and weeds to grow. Coarse sand locks pavers in place and drains properly.
Not leveling the ground before laying pavers means you will spend hours trying to get the surface even, and you still will not succeed. Spend the time on the base — it is the only part that matters.
Laying pavers on soil with no base at all works for a season or two, then the pavers sink, crack, and separate. Do not do this, even for a small temporary patio.
Frequently Asked Questions
How much does it cost to lay a patio with pavers?
Material costs vary by region and paver type, but a typical 12-by-16-foot patio (192 square feet) runs $400 to $1,200 in materials: pavers themselves are $2 to $6 per square foot, gravel and sand are $50 to $150 total, and polymeric sand adds another $100 to $300. Tool rental for a plate compactor and wet saw is $80 to $150 for the project. Labor costs much more if you hire someone — expect $1,500 to $3,000 for installation.
Can I lay pavers on top of concrete?
Yes, but only if the concrete is level and in good condition. Sweep it clean, lay landscape fabric, add one inch of sand, and set pavers on top. You skip the gravel base because the concrete already drains and prevents settling. If the concrete is cracked or uneven, the pavers will follow those cracks and look bad.
What slope should the patio have for drainage?
A slope of one-eighth inch per foot (or one inch per eight feet) is standard and barely noticeable to the eye. For a 12-foot-wide patio, that means one and a half inches of drop from one side to the other. This keeps water from pooling on the surface. Check your slope with a level and a shim as you lay pavers.
How long does it take for polymeric sand to harden?
Most polymeric sands harden within 24 to 48 hours after the final misting, depending on humidity and temperature. Do not walk on the patio or let water run across it during this time. Check the product instructions — some brands are faster or slower than others.
Do I need to seal pavers after installation?
Sealing is optional and depends on the paver material and your climate. Natural stone pavers (slate, flagstone) benefit from sealing to resist stains and water damage. Concrete pavers are more durable but can be sealed for color enhancement. Sealing lasts two to three years and costs $0.50 to $1.50 per square foot. It is not required for the patio to function.
