1 1 The replicated grass surface shall demonstrate by independent,certified laboratory testing: • A minimum average Tuft-Bind(ASTM D-1335)of 8 lbs/force. 1 • A minimum breaking strength (ASTM D-2256)of 420/250(x and y direction)lbs/force. • An initial CI-Max (ASTM F-355-A) for the GeoGreen replicated grass of not more than 110 when installed in conjunction with the GeoFlo shock pad and dynamic drainage blanket. 1 IIL INSTALLATION 1 A. BASE CONSTRUCTION—TURF INSTALLATION: 1 Specific design criteria must include the following: I) The sub-base must slope a minimum of 1/2%(to a maximum of 1%)to the collector drains. 1 2) After sub-base has been properly graded, contoured and sloped as required, it shall be compacted using a three to ten ton vibratory roller, as close as possible to 95% Proctor Density. 3) Additional stone, cement or recycled materials may be installed as is necessary to attain specified finished grade 1 tolerances. Such materials should be compactable enough to provide a stable grade for installation of the turf and fine enough to allow for specified grade tolerance. These additional materials shall be graded to 1/4 inch in 10 feet tolerance, and compacted. 1 4) Finish grading equipment should consist of dual-plane laser-actuated box grader or small mini-grader. Large road graders can be used but are not recommended in all situations. Grading equipment that is not hydraulically-actuated by laser is also not recommended. 1 5) A minimum 6-inch wide x 12-inch deep concrete curb shall be excavated at the precise perimeter of the synthetic grass installation area. The curb shall be constructed with concrete (min. 3000 psi) to a uniform specified grade with a grade tolerance of no more than %.' grade deviation under a 10 foot straight edge. After cure time, a 1.25 inch x 4 inch treated 1 nailer shall be installed to specific perimeter line, by ramset or TapCon, to the newly installed and/or existing concrete anchor. The finished grade of the nailer shall match the perimeter-finished grade of the aggregate base. 1 6) To the inside of the concrete anchor a trench drain shall be installed. The trench drains shall contain flexible, perforated pipe as shown in the engineered design and shall be filled with '/."/." inch clean, fractured stone as is typical. Drains shall be properly graded to insure positive flow of water to outflow. The drains shall be tied in to the existing outflow drains. 1 B. GEOFLO SHOCK PAD AND DYNAMIC DRAINAGE BLANKET INSTALLATION: I) Global will use an electronic or staked grade grid, of not more than 25 feet separation, to establish finished grade of 1 stone base, before installing the GeoFlo blanket. Stone base should not deviate from specified finish grade by more than 1/4 inch under ten feet straight edge. 1 2) Blanket will be installed along full end-to-end length of the field, perpendicular to the direction of slope. The 4 feet or 8 feet wide rows should be installed starting at the crown (or highest grade elevation) and 'shingled' toward the lowest grade elevation (the protruding flange will be placed on the highest elevation side, and the flanged edge of the subsequent roll will be inserted completely under the un-flanged edge of the preceding row). The installation of the rows 1 of GeoFlo will continue in this manner until over the open stone of the perimeter collector drains,where a 2'wide row of pervious (perforated) GeoFlo will be placed, in the same manner. The GeoFlo row nearest the collector drain will be trimmed in width(from the un-flanged edge)to allow precise fit of a 2 feet wide pervious GeoFlo,to anchorage line. The 1 rows of GeoFlo will be bonded and moisture sealed, using a pressure-sensitive tape or Not Melt Glue, as supplied by Global, on all seams. All seams will be sufficiently tight to leave no gaps or irregularities that could reflect through the synthetic grass surface, however, care should be taken to maintain a minimum 1/4 inch separation to allow for thermal expansion. The drainage blanket may be temporarily held in place by stapling to wood nailer,even' few feet. 1 Global Synthetics Environmental.LLC • 6326 Highland Road • Baton Rouge.LA 70808 • 225.907.4763• www.oeosurf aces.com 8 RFP#12-10-03 1
