Paver and Slab Installation: A Complete Step-by-Step Guide
Laying pavers or slabs is one of the most rewarding outdoor projects you can take on. Whether you're shaping a new patio, a garden walkway, or a full driveway, the finished surface comes down to the prep work underneath it. This guide walks you through every stage of the installation process so your hardscape stays level, stable, and beautiful for years to come.

Power Through Your Base Compaction
A reliable plate compactor is the single most important piece of equipment for this job. The Stark USA 6.5HP gas-powered compactor delivers 4000 lbs of compaction force, more than enough for patios, walkways, and driveways.

| Bedding Material | Base Material | Advantages | Installation Notes | |
|---|---|---|---|---|
| Traditional Base | Coarse sand (also called concrete sand, adhering to ASTM C33 or CSA A23.1 FA1) | 3/4" crusher run, well-graded gravel (also known as 3/4" down "A" base) | A proven system used in many successful jobs. Materials are widely available and typically the most economical option. | Standard prep practices apply. |
| Free-Draining Base | 1/8" to 1/4" crushed clean stone (alternate: 1/8", 1/4" chip, or HPB / High Performance Bedding) | 3/4" crushed clean stone (also called ASTM No. 57 fifty-sevens) | Water drains efficiently. Less prone to frost heave and ideal for high-traffic or heavily used surfaces. | Geotextile fabric is required to keep fine soil from migrating into the clean base. The subsoil should be sloped to direct water away from the structure. Toward a runoff zone or below grade drain. The final paver surface should not vary by more than 1/8". |
Design & Excavation
1 Mark Out Your Design
a. Use whatever method you're comfortable with to outline your design on the ground. String lines and spray paint both work well.
b. Excavate at least 12" beyond the planned paver perimeter so you have working room.
2 Set Elevations
a. Drive stakes around the work area, mark the desired grade, and run string lines to mark the finished patio elevation. Slopes should fall at a minimum of 1.5%, which is roughly 1" of drop for every 6'.
b. Check your grade stakes periodically as you work to make sure nothing has been bumped or shifted.
3 Excavation (Table A)
a. Use the appropriate table below for your climate and site to calculate your total excavation depth.
Total Excavation Depth = Paver/Slab Thickness + 1" Bedding Sand + 4โ8" Base Layer
b. Remove the soil and sod below your string lines to match the calculated total excavation depth.
c. Compact the freshly exposed soil with a jumping jack or sheep's foot compactor. This step is essential to the long-term performance of your installation and must be completed before laying any geotextile or base material.
Table A
| Dry Climate | |||
|---|---|---|---|
| Project | Paver/Slab Thickness | Bedding Material Layer | Minimum Base Thickness |
| Patio / Sidewalk | x | 1" | 4" |
| Driveway | x | 1" | 6" |
| Cold Climate / Wet Soil | |||
| Project | Paver/Slab Thickness | Bedding Material Layer | Minimum Base Thickness |
| Patio / Sidewalk | x | 1" | 6" |
| Driveway | x | 1" | 8" |
Minimum base thickness depends on soil structure. Every job site is unique, so when in doubt, ask a professional.
Base Layer Compaction
4 Install Geotextile (Optional)
a. Geotextile fabric helps prevent premature settling and rutting. Use it especially in areas where soil remains saturated for much of the year, where there's a freeze-thaw cycle, or where the ground is clay-heavy, moist, or silty.
b. Allow at least a 12" overlap on the downslope side.
c. Cover the compacted soil completely, including the vertical sides of your excavation.
5 Spread and Compact Your Base Layer
a. Spread the base material evenly across the work area. Reference Table A to confirm your required thickness.
For 7000 lbf reversible plate compactors: Spread and compact in 4" lifts. The base should extend at least 6" beyond the finished paver perimeter. Base is compacted enough when a 10" spike takes three hard hits with a 2 lb hammer to drive into it.
For 5000 lbf reversible plate compactors: Spread and compact in 2" lifts. The base should still extend 6" beyond the finished paver perimeter. Again, base is compacted when a 10" spike takes three hard hits with a 2 lb hammer to drive in.
b. Keep adding and compacting layers until you're about 2" + paver thickness below your finished grade.

a. Place your levelling guides โ 1" pipe, electrical conduit, or wood strips โ onto the compacted base.
b. Set the guides at the correct height so the bottom of the screed bar sits 1" above the compacted base.
c. Fill in the area between the guides with your final base layer. Run a 2x4 board along the levelling guides to spread and level the material to within 3/8" of finished grade. Compact this final lift just like the earlier ones.
7 Confirm Your Final Base Height (Diagram A)
a. Set a test paver or slab on the prepared base. If the surface sits more than 1" below your finished grade line, add more base, screed it level, and compact it again until the 1" gap is reached.
Edge Restraints & Bedding Material
8 Install Edge Restraint
a. Use the edge restraint of your choice. Snap Edge is our recommendation. Follow the manufacturer's directions closely.
9 Bedding Material
a. Set your levelling guides โ 1" pipe, electrical conduit, or wood strips โ onto the compacted base.
b. Set the proper height so the bottom of the screed bar finishes 1" above the compacted base.
c. Fill the area between the guides with bedding material. Spread and level the material to an uncompacted nominal 1" (25 mm) thickness.
d. Slide a 2x4 board along the levelling guides to spread and level the bedding material smoothly.
Installing Pavers & Slabs
10 Lay Down Pavers
a. Use string lines as guides to keep your joint lines straight.
b. Pull pavers or slabs from several bundles at once to mix color variation naturally.
c. Cut and split pavers or slabs with a concrete saw or paver splitter. Always wear a respirator when cutting.
d. When installing pavers or slabs, make sure each block is in contact with the previously placed piece, then push it into place. Avoid setting pavers or slabs on the bedding material before sliding them into position.
