TerraLite Engineered Fill Design Advantages
Edinburg TerraLite™ engineered fill is an engineered shale backfill that provides a lightweight, stable, and cost-effective alternative to traditional fill materials for infrastructure, commercial development, utility, transportation, and geotechnical applications.
Produced from the Edinburg Formation at Troutville Quarry, TerraLite engineered fill helps engineers, contractors, and developers address challenging site conditions by reducing structural loads, improving drainage, minimizing earth pressures, and providing predictable performance in critical backfill applications.
Why TerraLite
Engineered Fill?
A Smarter Alternative to Traditional Fill
Not every project is best served by conventional soil, clay, or aggregate fill.
TerraLite engineered fill is a lightweight engineered backfill material designed to improve constructability and support long-term project performance. Its engineered gradation promotes drainage and consistent compaction while helping reduce settlement and loading concerns.
Key Benefits:
Lightweight Fill
TerraLite engineered fill helps reduce structural loads and settlement, making it well suited for projects where weight reduction is an important design consideration.
Improved Drainage
Its engineered gradation promotes drainage and helps reduce hydrostatic pressure behind walls, structures, and embankments.
Cost-Effective Alternative
TerraLite engineered fill compacts easily and provides reliable, repeatable performance across a variety of site conditions.
Predictable Compaction
An economical alternative to imported fill, clay, dirt, or traditional aggregate materials.
Local Supply
Produced at Troutville Quarry, helping reduce haul distances, transportation costs, and project complexity.
Common Applications
