The Science
Behind the Sealant
We exist because the current standard isn’t good enough — and cities are the ones paying for it.
WHAT IT IS
Advanced Mortar Engineered for Microtrenching
Ultimate Street Armor bonds permanently to both asphalt and concrete. It fully seals the trench, prevents water intrusion, and preserves street integrity — fast cure, minimal disruption, long-lasting durability.

Tested to Standards That Matter
ASTM C109
Compressive strength from 4 hours to 28 days
ASTM C190
Superior tensile resistance against cracking
ASTM C348
High flexural strength with microfiber reinforcement
ASTM C157
Extremely low shrinkage under 0.04%
ASTM C191
Rapid and precise set times
ASTM C882
Tenacious bond strength exceeding industry standards
ASTM C1202

Why It Performs
Built for Every Stress a Street Will Face
Tenacious Adhesion
Bonds to asphalt and concrete — no gaps, no separation, no failure
Mechanical Performance
Withstands compressive, flexural, and tensile loads from heavy traffic
High Early Strength
2,000+ psi in 4 hours — roads reopen the same day
Long-Term Durability
Low water absorption and near-zero shrinkage prevent cracking over time
