POROUS FLEXIBLE PAVING <br />Section 02795 <br />15-1207 <br />washer, as required to secure units in place. Tops of rings shall be between 6 mm to 13 mm <br />(0.25" to 0.5") below the surface of adjacent hard -surface pavements. <br />B. Install sand in rings as they are laid in sections by "back -dumping" directly from a dump truck, <br />or from buckets mounted on tractors, which then exit the site by driving over rings already <br />filled with sand. The sand is then spread laterally from the pile using flat bottomed shovels <br />and/or wide "asphalt rakes" to fill the rings. A stiff bristled broom should be used for final <br />"finishing" of the sand. The sand must be "compacted" by using water from hose, irrigation <br />heads, or rainfall, with the finish grade no less than the top of rings and no more than 6 mm <br />(0.25") above top of rings. <br />3.05 INSTALLATION OF GRASS <br />A. Grass coverage on the sand -filled rings must be completed within one week. Sand must be <br />re -installed and leveled and Grasspave2 checked for integrity if rings become exposed due to <br />wind, rain, traffic, or other factors. (Choose one paragraph below to meet grass installation <br />method desired.) <br />Install thin sod directly over sand filled rings, filled no higher than the top of the rings. <br />Sod strips should be placed with very tight joints. Sodded areas must be fertilized and <br />kept moist during root establishment (minimum of 3 weeks). DO NOT DRIVE ON <br />SYSTEM: Sodded areas must be protected from any traffic, other than emergency <br />vehicles, for a period of 3 to 4 weeks, or until the root system has penetrated and <br />established well below the Grasspave2 units. <br />B. Adequately water sod or grass seed to assure germination of seed and growth of root system. <br />3.06 PROTECTION <br />A. Sodded areas must be protected from any traffic, other than emergency vehicles, for a period <br />of 3 to 4 weeks, or until the root system has penetrated below the Grasspave2 units. <br />3.07 FIELD QUALITY CONTROL <br />A. Remove and replace segments of Grasspave2 units where three or more adjacent rings are <br />broken or damaged, reinstalling as specified, so no evidence of replacement is apparent. <br />B. Perform cleaning during the installation of work and upon completion of the work. Remove all <br />excess materials, debris, and equipment from site. Repair any damage to adjacent materials <br />and surfaces resulting from installation of this work. <br />3.08 MAINTENANCE <br />A. Maintain grass in accordance with manufacturer's instructions and as specified in Section 32 <br />92 00 Manufacturers of Turfs and Grasses. <br />B. Lawn Care: Normal turf care procedures should be followed, including de -thatching. <br />7 <br />
