Congratulations! You have decided to purchase “Tartan®”, Athletic Polymer Systems, athletic surfacing. This product is the finest on the market and will give many years of good service. In order for your urethane to perform, however, the substrate underneath must first perform correctly. We ask that you review the following recommendations with your architect.

This checklist is part of our efforts to give you accurate information in a timely fashion. By doing so, however, we mean only to be helpful. These recommendations are not a substitute for the architectural, engineering, or contracting work that must be done before our product can be installed. No warranty is created, either expressed or implied.

    • Read about testing the mercury in running tracks
    • Soil Study & Recommendations for Structural Section and Paving by Geotechnical Engineer. Design for light truck traffic.
    • Design of Grading Plan, Drainage Plan by a Registered Civil Engineer
    • Subdrainage
      • WARNING: Subsurface landscaping/storm drainage water MUST be excluded, siphoned off by sand/gravel underlayment, or vapor from this water could "pop" the track, interfering with footing and movement. Standard engineering practice for paving projects designates specific subgrade materials, their thicknesses/elevations, and drainage to prevent these conditions. This should be included with your geotech/design engineering study for light truck traffic.
    • Job Conditions
      • Other Trades shall be completely finished in the area to receive surfacing and adjoining areas shall be cleared during spraying operations. The building shall be dry.
    • Foreign Substances on Surface
      • No Paint, Oil, Grease, Track Coat, etc. Detrimental to Adhesion
      • Hydraulic fluid can be detrimental to adhesion even when covered with another lift of substrate.
    • Cure Time > 50 Days
      • All Substrates Cannot be Adhered to Until Fully Cured. This Can Take Anywhere from 45-60 Days. Longer is better. Scheduled Substrate Work at Beginning of Project, Athletic Surfacing Near the End.
    • Moisture
      • Vapor Transmission should be below 3 pounds/1000 square feet per 24 hours water
    • Moisture Barrier
      • Moisture Impermeable Liner Above the Sand and Below the Slab.
      • Flashed Up Sides of Slab ( |_______| shape, See our Catalog for Drawing)
      • No Holes Punched in Liner by Concrete Contractor! (Use “Castle Chairs” by Aztec Concrete Accessories, Fontana, CA or similar)
    • Level
      • Variation Not to Exceed 1/8. in 10 feet.
      • Differences across a Joint Not to Exceed 1/16. in 10 feet.
    • Sealers &/or Curing Agents
      • Not to be Allowed. Detrimental to Adhesion.
    • Light Broom Surface
      • Excessive crust is detrimental to adhesion.
    • Recommended Concrete Testing at Job Site
      • 7 Day Break, 28 Day Break
    • Drainage
      • Insure that Water Will Drain AWAY from Track to Drainage System
      • Underground Drain System Recommended if Infield is Turf (A Slot Drain Is Not Always Enough)
    • Level
      • Variation not to exceed 1/8. in 10 feet.
      • Outdoor Tracks: The IAAF specification is 1% max cross slope. This can be achieved by setting the asphalt screed at about 0.8% average cross slope. Note: Typical minimum slope for good drainage is 1%. High School rules are 2% max cross slope. IAAF specifications for High Jump are not to exceed 0.25% in the direction of approach.
    • Asphalt
      • 3” Minimum Asphalt over 6” Minimum Roadbase
      • Stabilometer Value 32 Minimum (>35 Recommended)
      • Recommended Asphalt in Top 1.5” Lift Only: 3/8” Minus Aggregate, Sand Equivalent 30 +/-, Oil 6.3 +/- 0.5% on Dry Aggregate
    • Inspection at Job Site
      • Prior to Paving: Subgrade Level and Compaction to Spec Inspected. Especially near curb.
      • Nuclear Compaction Test Min 90% (95% + Min Recommended)
      • Temperature inspected during paving (no blue smoke, no “taffy” asphalt)
      • Tack Coat Applied Between Lifts
    • It is not possible to know exactly how much remedial work must be done on old substrates or floors until the work begins. It is advisable to set aside both contingency times and monies for the renovation or replacement of existing surfacing.
    • Existing substrates must meet the same recommendations as provided above for new construction.

You may wish to show this checklist to your general contractor, concrete contractor, or asphalt contractor as well. The above services or inspections are not provided with a surfacing subcontract.
