PAVING STONE COMPONENTS
- Willow Creek pavers
- Aggregate base material
3/4-inch crushed stone (including finer particles) typically used for road base.
- Bedding sand
Coarse, washed sand suitable for masonry.
- Edge restraints with 3/8” x 10” landscape spikes
- Joint sand
Dry, washed sand, free of large aggregate that would prevent it from freely flowing into joints. Polymeric joint sand may be used to prevent loss due to water or erosion.
- Willow Creek Paving Stones Underlayment Fabric (if necessary)
- Paving-stone sealant (optional)
Step 1 - Excavating
Before excavating, contact your local utilities to identify any underground cables and pipes in and near the project area. Use spray paint to mark the perimeter of your project area. Excavate beyond the area to be paved by a distance equal to the depth of base required. Excavate to a depth that allows 2.375 inches for paving stones, 1 inch for bedding sand and the required compacted aggregate base.
Final grade should slope away from building foundations by a minimum .125 inch per foot to ensure proper drainage. All paved surfaces should include some slope for drainage. With the aid of a transit or level, it is often helpful to pound temporary guide stakes to the correct grade at several locations in the project area.
Use a hand tamper or vibrating plate compactor to pack down any loose soil remaining in the excavated area.
Willow Creek Paving Stones Underlayment Fabric is recommended under the aggregate base where certain soil conditions exist — for example, in poorly drained, fine-grain soil such as clay or silt. By keeping the soil sub-base and aggregate base separate, this geotextile prevents the soft underlying soil from mixing with the crushed stone and diluting its strength. Place the Underlayment Fabric on top of the entire excavated area, including up the sides.
Step 2 - Compacting Aggregate Base
Place and compact uniform layers of aggregate base material throughout the excavated area until the required depth and slope is achieved. Best results will be achieved by using a vibrating plate compactor.
Slightly moisten dry base material and compact in layers of no more than 4 inches at a time. Start at the perimeter and work your way toward the center, overlapping each previous pass. Make at least two complete passes to create a flat, smooth base.
Step 3 - Setting Screed Guides
Paving stones are laid on a 1-inch layer of bedding sand. Screed guides (see tool list) are used to level the bedding sand. Set screed guides parallel to each other on the compacted aggregate base and check grade. The top of the screed guides will be the top of your sand bed and will determine the pitch and flatness of your paver surface.
Step 4 - Installing Edge Restraints
To prevent lateral movement of the paving stones and to ensure proper interlocking, edge restraints should be installed on top of the crushed-stone base on all unrestrained edges of your project area. Install edging initially on only one or two sides of the project area.
This is where paver placement will begin. If possible, begin at a long, straight edge. After all paving stones have been laid, install the remainder of edging. Ribs of edge restraints may be easily cut to permit bending of the restraints for curved edges. Stake edge restraints at all ends, leaving no more than 18 inches between spikes.
Note: Circlestone™ comprises concentric rings of paving stones placed around one center paving stone. After all Circlestones are installed, place edge restraints around the perimeter of the project area. For more information, download the Circlestone Estimating Guide.
Step 5 - Screeding Sand Bed
Carefully spread bedding sand around and between the screed bars to form a setting bed for the paving stones. Screed the sand by drawing a 2" x 4" board or other straight-edge across the top of the screed guides. Then remove the guides and use a trowel to fill in the voids with sand.
Step 6 - Laying Paving Stones
In general, lay the first paving stones against the longest section of edge restraint. If possible, start at the low end of the grade and work uphill to keep paving stones from shifting during construction. Select paving stones at random from different product pallets to get good color distribution. Work alternating from right to left, then left to right, completing one row at a time. String lines will help keep rows straight. Set the paving stones carefully into the sand; do not press or hammer them.
Place paving stones directly next to each other. The ribbed edges on the paving stones will ensure proper spacing. Continue adding paving stones until you’ve completed your pattern.
Note: When installing Circlestone, mark the center of the project area and begin laying paving stones in concentric circles from the center outward. See the diagram in the Circlestone Estimating Guide for proper placement of Circlestone components.
Step 7 - Cutting Paving Stones
Paving stones may need to be cut to fit curves, corners and angles, or to go around objects. Mark the paving stones and cut them using a saw equipped with a diamond-tip blade for the cleanest results.
A guillotine paving-stone splitter or mallet and chisel also may be used. Cut paving stones to fill any remaining gaps to maintain patterns. Gaps less than .375 inch can be filled with sand.
Step 8 - Compacting the Paving Stones
Finish installation of edge restraints. Sweep the paving-stone surface to remove debris. Make two passes over the surface with the vibrating plate compactor to embed paving stones into the bedding sand. Make any final adjustments in alignment or leveling at this time.
Step 9 - Joint Sand
Sweep dry joint sand over the paving stones and work it into the joints with a push broom. When desired, use polymeric sand to prevent loss due to water or erosion. Install polymeric sand per manufacturer's instructions. Make at least two more passes over the finished installation with a plate compactor, the second pass at an angle to the first, to level surface, firmly seat paving stones into bedding sand and force sand into the joints to ensure they interlock properly. Finally, sweep off excess sand.
*Use dry, washed sand, which meets ASTM C14 and is no less than 30% 1/8th inch particles. Polymeric joint sand may be used to prevent loss due to water or erosion. See manufacturer’s instructions when using.
Step 10 - Sealant (Optional)
A sealant may be applied to the finished surface to protect paving stones against stains, enhance color and stabilize joint sand. Sealants are available from your Willow Creek Paving Stones distributor.
