Poured in Place
Product Specification

PART 1 - GENERAL

Work Details:

This work includes furnishing and installing GT Impax recycled poured rubber surfacing.

GT Impax recycled poured rubber surfacing shall be poured in place and trowelled to
provide for a resilient, seamless rubber surface installed over the specified base. The
surfacing provider shall be responsible for all labor, materials, tools, equipment, and
applicable taxes to perform all work and services for the installation of the surface. The
surface shall be stable and slip resistant to comply with all requirements set forth in the
Americans with Disabilities Act.

Quality Assurance & Compliance Details:

Impact Attenuation - ASTM F1292-04: |mpact attenuation test results will be provided to the
owner or owner's representative. These test results shall be certified and submitted on the
letterhead of an independent testing lab. Impact attenuation test results shall meet or
exceed Consumer Product Safety Commission Guidelines for impact attenuation (G-max and

Head Injury Criteria (HIC).

Accessibility of Surface Systems - ASTM F1951-08: All Playground surfacing products must
pass testing to ensure wheelchair access under and around playground equipment as
required by the American Disabilities Act.

Coefficient of Friction - ASTM D2047-82: All products must meet a minimum standard on
coefficient of friction of .9-wet, 1.0 dry.

Permeability. Product shall meet or exceed a coefficient of permeability of 0.4 gallons per
square yard per second.

Flammability of Finished Floor cover - ASTM D2859: Product shall meet requirements of
ASTM D2859.

Tensile Strength - ASTM D412-87: This test indicates a product's ability to stretch, and how
far it will stretch before it breaks. Test results for wear course must be a minimum tensile
strength of 60.

PSI and minimum % elongation @ break of 140%.

IPEMA Certification: Manufacturer must provide proof of certification. “In the interest of
public playground safety, IPEMA provides an independent laboratory which validates a
manufacturer's certification of conformance to ASTM F1292-04. A list of current validated
products, their thickness and critical heights may be viewed at www.ipema.org.”

Submittal Details:

Submittal packages shall include but not be limited to: (1) product samples, (2) supplier's
written warranty, and (3) independent laboratory results.

PART 2 - MATERIAL DATA:

Polyurethane Primer and Binder - 100% Single Component Polyurethane Binding Agent -
Methylene Dephenyl Isocyanate (MDI) based binder.

Aromatic Binder - All projects will include aromatic binder unless project specifies the use
of aliphatic binder. The natural properties of the aromatic binder is to present a yellow tint
which may cause some EPDM/TPV colors to amber. The yellowing affect is more common
on lighter EPDM colors and will wear off with foot traffic and weathering.

Aliphatic Binder - This binder is available upon request but at an added cost to the over all
project. Aliphatic binder is all clear providing full EPDM/TPV color from day one. This
binder has a higher resistance to ultra violet light and provides a greater resistance to wear.

Impact Course - The impact layer is to be a precise combination of 100% recycled black
Styrene Budadine Rubber (SBR) and polyurethane binder. SBR is manufactured as a liquid,
poured into molds and generally used by the automobile industry. This recycled rubber is
shredded, mixed with binder and hand-trowelled to create a seamless application. The impact
course thickness, as specified by owner or architect, must be composed of recycled rubber and

free of foreign matter.

Wear Course - The wear course is made of Ethyl Propolyne Dione Monomer (EPDM)
or Thermal Plastic Vulcanized (TPV) pigmented rubber granules with polyurethane binder.
Thickness of the wear course shall be a minimum 1/2".

EPDM- The granule size will be 1-3 mm in diameter.
TPV- The granule size will be 1-4 mm in diameter.

PART 2 - MATERIAL DATA (Continued)

Colors - The color of GT Impax recycled poured rubber surfacing will be indicated on plans.
Owner or owner's representative will be responsible for selecting standard blends. Selection of
either standard color blends or custom color blends must be made at time quotation is being
requested. EPDM/TPV colors are available in 100% black and a variety of colors. Ask your
GameTime representative for available color combinations.

Note: If graphic designs and color transitions are used, they shall be full wear course depth.
Color(s) to be determined by architect. Graphic Templates are the responsibility of the
Architect or owner.

Physical Properties:

Tensile Strength (ASTM D412) 60 PSI, minimum
Elongation at Break (ASTM D412) 140%, minimum
Flammability (ASTM D2859) Pass
Coefficient of Friction (ASTM D204)
Wet 0.9, minimum
Dry 1.0, minimum
Water Permeability 0.4 gal. /sq. yd./sec., minimum

PART 3 - SUB-BASE TYPES & DETAILS:

Sub-base Requirements - The base shall have the specific maximum slope (2%) and shall vary
no more than 1/8” when measured in any direction with a 10° straight edge.

Stone - The density requirement is 90% to 95% compaction with final condition of stone as level
and stable so as not to shift when traveled on or during surface installation process. A
compaction test is required and must be submitted to GameTime prior to installation of poured
rubber surfacing. Failure to provide proof of compaction test will void 5-year warranty of PIP
surfacing should signs of sub-base failure occurs.

Depth: 4 inch minimum thickness.

Slope: Stone elevation shall maintain %” per foot toward low end.

Porosity: Base course shall maintain porosity for direct drainage.

Enclosure: Stone base course must be surrounded by a retaining curb.

Drainage: Subsurface drainage is recommended under and around a stone base.
Perforated pipe or similar system is acceptable.

Tolerances: VY," in any 10-foot direction and 1/8” in any 3-foot direction.

Stone Selection: It is critical that different size stones are used so that the base shall be

uniformly mixed. The material shall be wetted during mixing operations if
necessary for proper blending.
