0 PRODUCTS <br /> GREEN LANDSCAPING ALTERNATIVES FOR A SUSTAINABLE FUTURE <br /> BASIC INSTALLATION FOR CORE Gravel 60-40 (Commercial Grade) <br /> COREgravel - Honeycomb Gravel Stabilizer Panels: <br /> Panels area ± 45" x ± 39" x 1 3/5" (1.15 m x 1.0 m x 40 mm) (MEDIUM) (JUMBO panels <br /> also available = 2X medium panel) heavy duty black injection-molded polypropylene panel <br /> having a factory applied geotextile fabric fused to the bottom and are capable of supporting <br /> wheelchairs and occasional light truck traffic. Compressive strength is tested under ASTM <br /> D 1621-04a and is 1016 kg/0.0175 m2. Loading capacity is > 300 tons/m2, >380 psi, when <br /> filled with gravel over the specified base. <br /> CORE GRAVEL HONEYCOMB CELL INFILL MATERIALS <br /> Specifier Notes: <br /> A. For a permeable system, fill cells with clean, angular or round stones, gravel or <br /> decorative stones. <br /> B. Infill gravel sizes ranges between 1/8" to 1/2", but the ideal size is 3/8", and can be <br /> either clear or pre-washed of all fines before delivering to the site. No gravel less than <br /> 1/8" nor more than 1/2" is recommended. <br /> D. Install infill gravel by back-dumping into the cells from buckets mounted on rubber-tired <br /> tractors. Avoid sharp turns of the tractor, driving only on gravel-filled cells. Spread gravel <br /> laterally from the pile using power brooms, blades, flat bottomed shovels and/or wide <br /> asphalt rakes to fill the cells. Depending on the size of the project, you can compact the <br /> gravel with a vibrating plate compactor. If using pea gravel, no plate compaction is <br /> necessary. <br /> INSTALLATION <br /> 1. Excavate area allowing for unit thickness and top layer. Leave 50 mm (2.0 inches)for <br /> COREgravel@ 60-40 (40 mm) and top layer (10 mm) to meet final grade. <br /> 2. Excavate and shape foundation soils to grades, elevations, and dimensions as necessary <br /> for your site,or as per drawings.Be sure water will flow away from any structures. <br /> 3. If site requires a structural base,fill with 3/W road crush as necessary.A typically homeowner driveway <br /> will require a minimum of 2"of road crush,but site specific conditions may call for a deeper subbase. <br /> Maximum base layer:6"(i.e.parking lot). <br /> 4. Compact your base layer with a vibratory plate, compactor, or roller. <br />
