• 1 Cubic meter of TDA is equal to approximately 50 recycled passenger tires (1000 lbs).

• While being environmentally conscious, TDA is also often the most cost effective solution.

• Cold regions are uniquely suited for the use of TDA.

TDA suits a variety of different civil engineering uses

​

• Frost boil repair

• Excellent in septic mounds in cold climates (as an insulator)

• Landfill leachate collection systems

• Sub-grade insulation for roadways

• Lightweight insulating back-fill for wall and bridge abutments Lightweight fill for roadways over peat bogs or weak clay

• Bank stabilization

Key benefits of the TDA product

• Good thermal insulator & reduces frost penetration (8x better than crushed rock/gravel)

• Drainage capacity 10 to 100 times higher than gravel

• Lightweight (1/3 the weight of crushed rock)

• Low earth pressure (1/2 the pressure 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 pounds from the waste stream

• 1/3 the weight of crushed rock = 1/3 the transportation cost

BASIC GUIDELINES

For the use of TDA products in construction activities

​

• Geotextile material should be used to minimize infiltration of soil particles into TDA voids.

• Basic construction safety precautions should be used, including protective shoes/gloves, and removal of excess material from the site.

• The final height of the TDA should be limited to 1 meter.
  Or, 3 meters (width of 1m) in applications where TDA is placed in a trench enveloped by soil and/or structural materials.
