Hydrogrow Mix: A mixture made &om several commercial products including: 1)cr�ss-Iinked � <br /> polyacrylimide (<0.1%)polymer, which is non-toxic and neutral in pH, and will absorb l�Q to 350 times <br /> its weight in water&om most tap sources; 2) ZeoPro zeolite minerai, amended with small amounts of <br /> starter fertilizers, from Zeoponix, Inc.; 3)Isotite porous ceramic, designed to hold lazge amounts of <br /> water without physical degra.dation ar change of size oF particle, from Sumitomo Crroup; 4)and <br /> aggromolated Humate, a natural source of nutrients and micronutrients, from Tri-C Enterprises. <br /> C. Grasspave2 Cnass Paving Units: Lightweight injection-molded plastic units O.�x0.5x0.02� m <br /> (20"x20"x1" t�igh, 2.7 ft2 each) with hollow rings rising from a strong open grid allowing maximum <br /> grass root penetration and development. The plastic shaIl be 1Q0%post-consumer recycted plastic <br /> resins, predominately HDPE, with muumum 3%cazbon black cancentrate added for W protection. <br /> Loading capability is equal to 402 kg/cm2 (�700 psi)when filled with sand, over an appropriate <br /> depth of roadbase. Standard color is black. Uait weight= SIO g (18 oz.), volume = 8% solid. Units <br /> may also be shipped in pre-assembled into rolls that vary from 10 square meters (1 Q8 s fl to 125 square <br /> meters (1345 s�}. <br /> D. Sand: Obtain clean sharp sand(washed concrete sand}to fill the 2� mm (one inch) high rings <br /> and spaces between the rings when seeding or using 13 mm(half inch) thick sod(soil thickness}. <br /> E. Grass: Use species resistant to weaz by tra�c generally a Btue/Rye/Fescue mix used for axhletic <br /> fields in northern climates,and Zoysia, Fescue, or Berrnuda rypes in southem climates. <br /> (Check with Iocal sod and seed suppliers for preferred mixtures.) <br /> (Dedicated firelanes can use same grass species used on surrounding turf.) <br /> - (Parking apptications require greatest wear-resistant species possible, generally available only by <br /> seed or sprigging.) <br /> (Choose one of the following paragraphs to suit project requirements.} <br /> 1. Sod: Use 13 mm(0.5") thick(soil tluckness) rolled sod from a reputable local grower. <br /> Species should be wear resistant, free from disease, and in excellent condition. Sod sha.11 be grown in <br /> sand or sandy loam soils oniy. Sod grown in soils of clay, silt, or high organic materials such as peat, <br /> will not be accepted. <br /> 2. Seed: Use seed materials, of the preferred species for local envirotunental and projected <br /> tr�c conditions, from certified sources. Seed shall be provided in containers clearly labeled to show <br /> seed name, lat number, net weight, %weed seed conteat,and guaranteed% of purity and gerrnination. <br /> Pure Live Seed types and arnount shall be as shown on plaas. <br /> F. Mulch: (Needed only for seeding.) Shall be of wood or paper cellulose types of commercial <br /> mulch materials often used in conjunction with hydroseeding operations. Mulches of straw, pine <br /> needles, etc. will aot be accepta.ble because of their low moisture holding capacity. <br /> G. Fertilizer: A commercial "starter" fertilizer, with Guaranteed Analysis of 17-23-6, or as <br /> � recommended by locai grass supplier,for rapid germination and root development. <br /> 6/25/2007 <br />
