Engineered Lightweight Fill (ELF) is one of the most common uses for TDA in highway projects. It is lightweight, structurally stable and, therefore, functions as an excellent alternative to conventional soil fill when constructing highway embankments and slide repairs. It improves stability, reduces lateral and vertical pressure plus potential settlement problems

TDA have been proven to be a superior substitute for gravel or structural fill in backfill applications. When TDA is properly placed behind a retaining wall for backfill, it significantly reduces the lateral earth pressure against the wall. TDA is a free-draining material with the same drainage rates as traditional aggregates.

There are multiple ways in which TDA can be used in landfills. Some of these include leachate collection systems, recirculation trenches, gas collection and venting systems, operations layers, cap closures, and alternative daily cover.

Trains typically create a lot of vibrations that filter into the neighborhoods. TDA acts as an energy absorber and helps attenuate these issues.
