Tire Derived Aggregate (TDA)


  • Good thermal insulator & reduces frost penetration (8x better than crushed rock/gravel)
  • Good Drainage/Permeability (50x the permeability of earth, equivalent or better than crushed rock)
  • Lightweight (1/3 the weight of crushed rock)
  • Low earth pressure (1/2 of soil)
  • Compressible
  • Cost effective (TDA is often the cheapest alternative if you need it's unique properties)
  • Inert (no harmful leachate)
  • Using tire shred for these projects removes millions of lbs from the waste stream
  • 1 Cubic meter of tire shred = 40-50 passenger tired (900 lbs)
  • 1/3 the weight of crushed rock = 1/3 the transportation cost


Tire Shred is Useful as a replacement for crushed rock/stone aggregate in Civil Engineering Projects.

  • Landfill Leachate Collections Systems
  • Landfill Gas Management Systems
  • Insulation fill for highway edge drains
  • Subgrade Insulation for Roadways
  • Lightweight insulating backfill for wall and bridge abutments
  • Lightweight fill for roadways over peat bogs or weak clay
  • Bank Stabilization
  • Subgrade fill and embankments
  • Excellent for Septic System Drainage Fields
  • Other Uses
