BENEFITS & PROPERTIES

Frost-Resistance

Non-frost-susceptible aggregate for cold-climate and below-grade applications.

Enviro-Rock is formed with a cellular glass structure containing sealed air pockets within each particle. These closed internal cells help limit water penetration into the particle, while the open spaces between aggregate pieces allow water to move freely through the placed material.


Replaces Frost-Sensitive Fill
Provides a non-frost-susceptible fill option where conventional materials may be vulnerable to frost.


Non-Frost-Susceptible
Designed for applications where frost-sensitive materials and freezing conditions are a concern.


Reduce Frost-Movement

Helps reduce the potential for frost-related heaving and seasonal ground movement.

Why Frost Resistance Matters


In cold climates, frost-susceptible soils can retain and draw moisture into the freezing zone. As that water freezes, ice lenses can develop and expand, causing slabs, pavements, utilities, and other structures above to heave or move.

Enviro-Rock provides a non-frost-susceptible aggregate layer without the fine soil matrix that contributes to frost-heave development. Its coarse aggregate structure helps limit the conditions needed for damaging frost movement within the fill layer.

This makes Enviro-Rock well suited for foundations, exterior slabs, roadways, utility trenches, and other applications where seasonal freezing can affect long-term performance.


Where Frost Resistance Makes a Difference

Foundations & Slabs-on-Grade

Helps reduce frost-related movement beneath slabs and foundations in areas exposed to seasonal freezing.

Roadways & Embankments

Provides non-frost-susceptible fill beneath pavement systems where frost heave can affect long-term performance.

Utilities & Trench Backfill

Helps limit frost-related movement around buried utilities and other shallow below-grade infrastructure.
