Seven Step Installation Guide

1Planning:Start with a good level measure and draw a diagram of the area, noting any existing structures such as buildings, fences and other paved areas.

2Preparing:Contact your local utility companies before you begin excavation. Stake out an area approximately 12” larger than the area to be covered. Plan to slope the blocks away from the buildings in the direction of normal drainage.

3Excavating:For areas limited to pedestrian traffic, a base of 4”- 6” of processed gravel is recommended - excavate 7”- 9” to allow for base material.For vehicular traffic a base of 6”- 8” of processed gravel is recommended - excavate 9”- 11” deep.

4Installing the Base:After installation of site specific geotextile fabric, compact the surface of the excavated soil then fill the area with 3/4” minus crushed stone or aggregate approximately 5” thick. Compact this with the plate compactor. Continue to add gravel in layers until the base is approximately 3” to 3-1/2” from the desired level of the finished grade. The slope should be 1/8” per foot. Install a level line across the area. On the stake that is at the end you want to slope towards, move the line down 1/8” for every foot. The distance from the line to the base should be equal all along the line.

5Edge Restraints: (Optional) UltraLok blocks have a positive interlocking connection which make edge restraints optional.

6Cutting:Measure and mark the blocks then cut with an abrasive blade or hammer and chisel.

7Compacting & Setting:Sweep the surface to remove any debris. Spread two inches of top soil and/or crushed stone into the joints. The soil can then be seeded to reinforce the area and create vegetation for an eco-friendly site.

You have now completed your project and the end result is an environmentally strong, value added and visually-pleasing site.
