Specifications include, but are not limited to: TURF SYSTEM: A. Turf Fiber: 1. The turf fiber must be tufted to the backing with a minimum tuft bind of 10 pounds.; 2. The tufted fiber weight shall be a minimum of 52 ounces per square yard.; 3. The turf fiber shall be non-abrasive and a minimum of 100 microns thick.; 4. The turf fiber must contain less than 100 ppm of lead in all colors.; 5. The turf fibers must be from the same dye lots. ; B. Backing Material: 1. Primary Backing: a. Primary backing must be a dual layered woven polypropylene material.; b. Primary backing system weight must be a minimum of 7.0 ounces/square yard.; 2. Secondary Backing: a. Secondary backing system weight must be a minimum of 22 ounces/ square yard.; b. Secondary backing shall saturate the primary backing and effectively lock the fiber tufts in place to the primary backing.; c. Secondary backing must be a heat activated polyurethane coating with no vegetable based polyols.; d. Secondary backing system shall have minimum tuft bind strength of 10 pounds. ; LINES, MARKINGS AND IN-LAID TURF: A. All line material is to be identical dimensionally and of the same material to that used for the main playing field fiber system.; B. Inlaid material as indicated on the drawings to be identical, except for fiber color, as the main turf field.; C. All lines and markings shall be accurately set and surveyed to within ½” tolerance of the location shown on the drawings and in conformance with specified field marking standards.; D. All lines and markings shall be installed prior to any installation of in-fill material. ; SYNTHETIC GLUE MATERIAL: A. Adhesive products shall be Nordot 34G, Mapei 2K, Turf Claw, hot melt technology or equivalent as approved by the engineer.; B. Any adhesive products required for the installation of a proposed turf system shall be purpose-suited to the system. The material and application methods shall be as recommended by the adhesive manufacturer.; C. Disposal of adhesive containers and unused adhesives as well as any fees resulting from such disposal shall be the responsibility of the Contractor.; INFILL MATERIAL: A. The synthetic infill material shall consist of a blend of graded, silica sand and treated and mixed ground rubber.; 1. Sand: specially-graded, dust-free silica sand shall be placed on the turf in a minimum quantity of 1 pound/ square foot and shall include test results that demonstrate the following minimum properties: a. Color – tan; b. Sand shall be round non-angular in shape; c. Roundness – 0.6+; d. Hardness - 0.6-0.8 on the Mohs Scale; e. Size – 1.00 mm ± 0.15 mm ; 2. Rubber: Rubber is SBR ambient (styrene butadiene rubber) rubber, color black, 10-18 mesh, that is 99% fiber free and is heavy metal safe.; B. The infill materials shall be installed to allow an exposed fiber of not less than ¼ inch after finish brushing and ½ inch after 180 days.; C. Sufficient quantities of the top dressing infill material must be stored on site at the time of installation to be used 180 days after the completion of the installation to mitigate the differential settling of high traffic zones on the field. This fill addition must be carried out by the Contractor within the time specified above.
