2-3/4" Peppered Granite 3-Piece Tribeca Cobble Random Bundle Paver | UNP2282M00740921

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
• All sands must meet ASTM C144 or C33 specifications, for best appearance and optimal performance, keep jointing materials approximately 1/8 in. below the chamfer (bevel edge) of the paver
• 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
