Percstone

The unique lattice work design of the Percstone environmental unit allows for sand, pea gravel or turf fillers, each of which creates its own distinctive look. These pavers work well in driveways, parking courts and other areas where drainage is a problem. Percstone is an erosion control unit that provides visual definition for the paved space. For tough spots that really require solid pavement but are unable to support it, Percstone is the answer.

Residential and Commercial Installation

  • 1. Excavate subgrade material to the depth required for particular application and compact the soil subgrade to at least 95% of modified Proctor Density. The base for Percstone is typically compacted ¾" modified stone. The thickness of the base depends on the load and the strength of the soil subbase as directed by site engineer, architect, or landscape architect. (For example, a typical fire lane or parking lot would require 8"-12" of stone.)
  • 2. Install edge restraint using concrete curb or concrete toe.
  • 3. The setting bed should be concrete sand conforming to ASTM C 33. Thickness of the sand should be 1". The sand should be properly screeded to proper elevation allowing 3-1/8" for the Percstone units. The screeded sand should not be saturated nor disturbed.
  • 4. Install Percstone units on bedding course in pattern desired allowing approximately 1/8" between units.
  • 5. Where required, cut Percstone units with an approved cutter to fit accurately, neatly and without damaged edges.
  • 6. Tamp Percstone units with mechanical vibrator uniformly level, true to grade and free of movement.
