4" x 6-7/8" x 2-3/4" Half Alpine Gray Brussels Premier Paver | UNP0290H00730921

Key Features

• One layer of DriveGrid™ stabilization grid between sub-grade and base material, recommended depth 8 to 10 in. below pavers for maximum stability and performance, use under standard base or permeable base
• Minimum 6 to 8 in. of 3/4 in. crusher run gravel (any road base standard in accordance with ASTM-D2940) compacted to 98% Standard Proctor Density (SPD)
• 1 in. thick of coarse sand in accordance with ASTM-D2940 screeded over base
• Minimum 6 to 8 in. of 3/4 in. clear open-graded stone compacted to achieve full particle lock up and consolidation
• 1 in. thick of 1/4 in. clear open-graded chip stone - (ASTM No. 8) screeded over base
• In some areas of the country and in some applications pavers are very successfully placed directly over concrete, concrete as a base is in itself quite strong, but it can affect the structural integrity of the paver particularly in vehicular applications, where the concrete below is sub-par
• This product has no special handling requirements
• Always install an edge restraint around the perimeter of any paver installation not restrained by building structures, "spike in" edge restraints come in plastic and various metals and work well for most applications, a concrete curb or a "sub surface concrete wedge" can also be installed to retain the edge
• Always use a protective polymer pad on the bottom of your compactor when doing the final compaction of the pavers, an alternative is to use a rubber roller compactor for the final compaction
• Any cleaner specifically designed for pavers may be used for color restoration or general cleaning, follow manufacturer's dilution rates and application procedures, always test a small area to make sure the results are as expected
