APPLICATIONS
STORMWATER
MANAGEMENT
The high permeability of TDA makes it an excellent drainage material for all types of grade drains, collection systems and stormwater applications.
ROAD CONSTRUCTION
TDA is ideal for weak foundation soils and can also be used as a replacement for conventional fill in embankments. In cold climates, TDA can also help mitigate the effect of frost.
LIGHTWEIGHT
BACKFILL
TDA utilized as backfill in foundation walls and conventional walls reduces lateral loading, drains water away from the foundation, and reduces heat loss.
SITE STABILIZATION
Existing lands can be made up of soft, muddy soil at low-lying grades. These properties need a stable foundation that can hold up overlying structures. Utilizing TDA creates a strong foundation, eliminating the risk of differential settlement or other failures.
SLOPE
STABILIZATION
Because TDA is lightweight and permeable, it is effective in reducing excessive loading on an unstable slope. An added benefit, TDA's high permeability permits drainage through the various layers and can dramatically reduce the potential hydrostatic pressures that promote slope stability.
LANDFILL
APPLICATIONS
TDA can be used as a drainage layer in leachate collection systems and landfill covers. Its properties also make it ideal for recirculation trenches and gas collection trenches/layers.
RESIDENTIAL
APPLICATIONS
-
Basement backfill
-
Driveways
-
Foundation pads
-
Retaining walls
-
Septic systems
VIBRATION MITIGATION
TDA can be used as a vibration dampening layer, protective cushion, and seismic isolation layer for earthquake engineering design because of its has a high vibration adsorption capacity.
PARKING LOTS
TDA has been used in parking lots for both stormwater management and site stabilization.
