BENEFITS & PROPERTIES

Structural Capacity

Lightweight fill with dependable load-supporting performance.

Enviro-Rock provides structural support while significantly reducing the weight of conventional granular fill. When properly placed and confined, it can be used in assemblies where load distribution, settlement control, and lower dead load are important, including slabs, foundations, backfill zones, and other load-sensitive applications.





Load Distribution
Helps transfer imposed loads through the fill layer


~1.0 MPa
Confined compressive performance at ~20% reduction


Structural Fill

Provides support within engineered slabs, foundations and other load-bearing assemblies

Why Structural Capacity Matters


Fill materials used beneath slabs, foundations, pavements, and other engineered assemblies must be capable of resisting applied loads while maintaining stability under compression.

Under modified EN 1097-11 confined testing, Enviro-Rock achieved an average compressive resistance of 0.429 MPa at 10% compression and 0.918 MPa at 20% compression.

Combined with its low unit weight, this allows Enviro-Rock to provide load-supporting performance while placing substantially less additional weight on the underlying soil or supporting structure.

Where Structural Capacity Makes a Difference

Slab-on-Grade & Foundations

Provides lightweight structural fill beneath slabs and foundation assemblies where load support and reduced dead load are important.

Retaining Wall & Structural Backfill

Supports backfill requirements while reducing lateral loading and dead load behind retaining structures.

Roadways & Embankments

Provides lightweight structural fill where bearing performance and reduced loading on underlying soils are important.
