INSTALLATION GUIDE
BEDDIING SAND INSTALLATION
Using screed rails on the compacted granular base, apply bedding sand at a maximum thickness of 1 in (25mm). By using a screed board along the top of the screed rails, the bedding sand will level evenly. Bedding sand should be compacted since Dimensional Flagstone slabs should not be compacted after installation.
FLAGSTONE INSTALLATION
· Begin by laying the individual pieces of Dimensional Flagstone on the screeded bedding material according to your detailed project plan.
· Push flagstone slabs directly together so the bottom edges butt tight. There is no need to space the slabs to create the necessary joint. Joint is pre-set in the unit.
· Cut units as needed to finish edges of installation.
· Note: To ensure proper color distribution, mix layers from several bundles at one time
JOINT SAND INSTALLATION
Once the flagstone pieces are installed, fill all joints with jointing sand suitable for large joints. Sweep the sand into the joints between flagstones until the joints are completely filled. Follow the jointing sand manufacturer’s recommendations for wetting the sand. You may need to repeat this process with more dry sand in a few days to completely fill the joints between individual slabs.
CAUTION: Dimensional Flagstone slabs should not be compacted after installation.
OTHER CONSIDERATIONS
You may want to apply a sealer to protect the flagstone slabs from spills and stains. Always use a high quality sealer specifically formulated for wet-cast concrete.

GENERAL NOTES FOR DETAILS
• Final designs for construction must be prepared by a registered professional engineer using the actual conditions of the proposed site and loads.
• Block size and placement shown are for reference only, individual blocks vary with installation pattern and product.
• Section shown is the minimum recommendation for pedestrian loading. Projects with heavier traffic or sites with poor soil conditions may require thicker gravel base, concrete curb edge restraint, and/or sand subbase.
• Provide adequate surface drainage to prevent ponded water.
