What You Need Before You Start
A paver stone patio is built in layers: soil preparation, a sand base, the pavers themselves, and joint sand to lock them in place. The work is physical but straightforward — you do not need special tools or experience, though renting a plate compactor (a vibrating machine that costs $40 to $60 per day) saves your back and produces a more stable surface. You will need a shovel, a level, a rubber mallet, a broom, a tape measure, and a circular saw with a masonry blade if you need to cut pavers to fit edges.
Before ordering pavers, measure the space where the patio will sit. Multiply length by width to get square footage. Pavers are sold by the square foot, and you should order 5 to 10 percent extra to account for cuts and breakage. The cost per square foot varies widely — clay brick pavers run $3 to $8 per square foot, while concrete pavers cost $1 to $4 per square foot, and natural stone (flagstone, bluestone) can reach $10 to $20 per square foot. Budget also includes sand, gravel, and joint sand, which together add roughly $0.50 to $1.50 per square foot.
Key Takeaways
- The patio sits on four layers: compacted soil, gravel base, sand bed, and pavers, each one essential to prevent settling and cracking.
- Proper slope (1/8 inch drop per foot away from structures) directs water away and prevents pooling that damages the patio and foundation.
- A plate compactor rented for one or two days is worth the cost because hand tamping leaves soft spots that cause pavers to shift.
- Joint sand between pavers locks them in place and prevents weeds; polymeric sand costs more but hardens when wet and lasts longer.
- The entire job typically takes three to five days for a 200-square-foot patio, depending on soil condition and whether you cut many pavers.
Prepare the Ground and Set the Slope
Mark out the patio area with chalk or string. Remove grass, weeds, and the top 4 to 6 inches of soil using a shovel. The depth matters because you need room for the gravel base (4 inches), sand bed (1 inch), and pavers (typically 2 to 3 inches). Dig deeper if the soil is clay or very soft — you may need 6 to 8 inches of gravel to reach stable ground.
As you dig, establish a slope that carries water away from your house or any structure the patio adjoins. The standard is 1/8 inch of drop for every foot of distance. On a 12-foot-wide patio, that means the far edge sits 1.5 inches lower than the edge nearest the house. Use a long level and a tape measure to check this as you go. Mark the high and low points with stakes so you can see the slope clearly before you add the base layers.
Once the ground is dug and sloped, compact the soil with the plate compactor or a hand tamper. This prevents settling later. Walk the entire area and tamp any soft spots. The soil should feel firm underfoot and not shift when you press down.
Add Gravel Base and Sand Bed
Spread 4 inches of crushed gravel or crushed limestone over the compacted soil. This layer drains water and provides a stable foundation. Spread it evenly and compact it with the plate compactor. Make two or three passes to lock the gravel in place. The gravel should not shift when you walk on it.
Next, spread 1 inch of coarse sand (sometimes called mason sand or paver base sand) over the gravel. Do not use fine sand or play sand — they compact too much and do not drain. Rake the sand level and check your slope again with the long level and stakes. The sand surface should match the slope you marked earlier. This is your final chance to adjust height before the pavers go down, so take time to get it right.
Do not compact the sand layer. The pavers will settle into it slightly as you place them, and the plate compactor will compress it further once all pavers are down. Compacting it now makes the final surface uneven.
Lay the Pavers in Your Chosen Pattern
Common patterns include running bond (like bricks in a wall), herringbone (45-degree angles), and basket weave (alternating direction). Running bond is fastest for a first-time builder. Start at one corner and work outward, placing each paver firmly into the sand. Tap it down with the rubber mallet until it sits level with its neighbors. Use the long level frequently — check both directions (lengthwise and across) to catch high or low spots before you move on.
As you work, you will need to cut pavers to fit the edges. Mark the cut line with chalk, then use a circular saw fitted with a masonry blade to cut through the paver. Wear a dust mask and eye protection — masonry dust is silica and damages lungs. Cut slowly and let the blade do the work; forcing it creates heat and can shatter the paver. If you have many cuts, a wet saw (which you can rent) is faster and safer.
Work in sections of 10 to 15 pavers at a time. Check the level and slope within each section before moving on. If a paver sits too high, tap it down. If it sits too low, lift it out, add a pinch of sand underneath, and reset it. This attention to detail during placement prevents a wavy surface later.
Compact the Pavers and Fill the Joints
Once all pavers are down, run the plate compactor over the entire surface. Make two or three passes, overlapping each pass slightly. The compactor vibrates the pavers down into the sand and locks them together. You will see the pavers settle slightly — this is normal and expected. Check the level and slope one more time after compacting; the surface should be even and the slope should match your original marks.
Spread joint sand (also called polymeric sand if you choose that type) over the entire patio. Use a broom to sweep it into the gaps between pavers. Work diagonally across the patio so the sand fills the joints rather than sweeping it out. Once the joints are full, sweep off the excess sand from the paver surface.
If you used polymeric sand, mist the patio lightly with a garden hose. The water activates a polymer binder in the sand, which hardens and locks the pavers in place. Do not soak it — just a light mist. Let it dry for 24 hours before allowing foot traffic. Regular sand does not harden; it stays loose and may need topping up after a year or two, but it is cheaper and easier to replace if needed.
Finishing Touches and Long-Term Care
Once the patio is complete and the joint sand is set, you can add edging if desired. Plastic or metal edging along the perimeter prevents pavers from shifting outward over time. Install it flush with the patio surface so it does not create a tripping hazard. Some builders skip edging on small patios; it is optional but recommended if the patio is more than 100 square feet.
To keep the patio looking good, sweep it regularly to remove debris and prevent moss or algae growth in damp climates. Every few years, top up the joint sand if it settles or washes away. If weeds grow through the joints, pull them by hand or spray with a herbicide designed for pavers. Avoid pressure washing on high settings, which can dislodge sand and damage the pavers themselves.
A well-built paver patio lasts 20 to 25 years with minimal maintenance. The most common failure — pavers settling unevenly or cracking — usually results from skipping the soil compaction or gravel base step. If you take time to prepare the ground properly, the patio will remain stable and level for decades.

Frequently Asked Questions
Can I build a paver patio on top of concrete?
Yes, but the concrete must be in good condition — no large cracks or heaving. Clean the concrete, then lay pavers directly on a 1-inch sand bed without the gravel layer. The concrete itself acts as the base. If the concrete is cracked or uneven, break it up and remove it; the extra work is worth avoiding a wavy patio later.
How long does it take to build a paver patio?
A 200-square-foot patio typically takes three to five days working alone, assuming the soil is in reasonable condition and you do not need to cut many pavers. Larger patios or complex patterns take longer. Renting a plate compactor saves a full day compared to hand tamping.
What is the difference between regular sand and polymeric sand?
Regular sand is loose and may wash out or settle over time, requiring occasional topping up. Polymeric sand hardens when wet and lasts much longer — often five to ten years without maintenance. It costs two to three times more per bag but saves work later. For a permanent patio, polymeric sand is worth the extra cost.
Do I need to seal pavers after installation?
Sealing is optional and depends on the paver material and your climate. Concrete pavers benefit from sealing in wet climates to prevent moss and algae. Clay brick and natural stone are more porous and may stain more easily, so sealing helps. Sealed pavers last longer and look newer, but sealing must be reapplied every two to three years.
What should I do if a paver cracks after installation?
Remove the cracked paver by lifting it out carefully with a flat pry bar. Scrape out the old sand, set a new paver in its place, and refill the joint sand. If cracks appear in multiple pavers shortly after installation, the base may be unstable — check that the gravel was compacted properly and the soil underneath is firm.
