TDA creates significant cost savings environmental benefits compared to alternative rock/stone aggregates.
-
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.
