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.
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.
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.
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.
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.
