High-Performance Structural Polymers & Slurries for Rapid Infrastructure Restoration
In heavy civil and military infrastructure, temporary asphalt patching and rigid mortar repairs are systemic liabilities. Dynamic axle loads, thermal contraction, and severe shear stress continually fracture conventional patch materials, creating recurring maintenance bottlenecks and dangerous Foreign Object Debris (FOD) hazards. GeoCHEM, Inc. supplies the Percol® System: a specialized suite of rapid-curing, low-viscosity structural polymers engineered to weld failed pavement matrices together permanently.
Formulated to restore mechanical cross-linking and full load-bearing capacity, Percol® slurries and polymers penetrate deep into micro-fissures to eliminate water intrusion, resist freeze-thaw spalling, and allow heavy transport or aircraft traffic to resume operations in as little as 10 minutes post-application.
The Engineering Advantage: Structural Mechanics of Percol®
Unlike brittle concrete caps or bituminous cold-patches that delaminate under load, Percol® polyurethane and resin systems are specified for critical sites due to their unique structural integrity and material flexibility:
- AASHTO & DOT-Grade Durability: Formulated for maximum thermal management, resisting severe freeze-thaw cycles, deicing salts, jet fuel, hydraulic fluids, and chemical degradation.
- Monolithic Structural Bonding: Low-viscosity resins exhibit extreme capillary action, penetrating deep into subgrade fractures to chemically weld fractured aggregate together at bond strengths exceeding the tensile capacity of original concrete.
- Flexural Modulus & Dynamic Load Transfer: Remains resilient under dynamic impact and heavy axle loading, absorbing vibration without fracturing or cracking surrounding pavement headers.
- Rapid-Curing Operational Readiness: Cures rapidly across a wide temperature spectrum—from sub-freezing conditions to extreme desert heat—minimizing lane closures and flight deck downtime.
Targeted Civil & Defense Applications
- Aviation & Military Readiness: Engineered alongside the U.S. Air Force for Rapid Runway Repair (RRR). Eliminates FOD risks on high-impact runways, taxiways, and military staging aprons.
- DOT Highways & Bridge Headers: Department of Transportation-approved for armored nosing, rapid expansion joint replacement, and deep spall repairs. Machine-dispensed systems allow full semi-truck traffic resumption within minutes.
- Industrial Logistics & Distribution Hubs: Built to withstand continuous, high-point wheel loads from hard-tired forklifts, reach stackers, and automated yard equipment in commercial warehouses and intermodal ports.
In the Field: CALTRANS Project Profile
Location & Scope: California Department of Transportation (CALTRANS) Bridge Deck Header Maintenance, El Cajon OH DR 57-362 Project.
The Challenge: Severe concrete spalling and header joint failure on a high-density freight corridor requiring immediate structural mitigation without extended highway closures.
The Structural Solution: CALTRANS maintenance crews deployed GeoSet Rapid Load-Bearing Concrete Repair Slurry to rebuild damaged bridge header joints. The low-viscosity resin restored full load-transfer capacity and permitted heavy semi-truck traffic resumption just 30 minutes post-application.
