Concrete & Asphalt Repair (Percol®)

Rapid Permanent Asphalt and Concrete Repair Percol® Polymers & Slurries: The Gold Standard in Infrastructure Mitigation

High-Performance Structural Solutions for Concrete and Asphalt Restoration

In critical infrastructure, "patching" is a liability—it leads to repetitive maintenance cycles and operational downtime. GeoCHEM, Inc. provides the Percol® System: a specialized suite of high-spec polymers engineered for permanent structural restoration. Whether it's a NATO runway or a high-traffic bridge header, Percol® delivers load-bearing strength and resumes full traffic operations in as little as 10 minutes.

The Engineering Advantage: Why Professionals Specify Percol®

Percol® polymers are formulated to solve the failure points of traditional materials by combining rapid-set chemistry with structural flexibility:

  • AASHTO & DOT Grade Durability: Engineered to withstand extreme thermal movement, freeze-thaw cycles, and chemical exposure (oils, fuels, and salts).
  • Monolithic Structural Bonding: Low-viscosity resins penetrate deep into fissures to create a chemical bond that exceeds the PSI of the original pavement, "welding" the substrate together.
  • Dynamic Load Distribution: Remains flexible enough to absorb vibration and heavy axle loading without delaminating, unlike rigid mortars that crack under stress.
  • All-Weather Reliability: Proven performance in sub-freezing winters and high-heat desert environments.

Targeted Solutions for Critical Environments

  • Aviation & Military Readiness: Developed with the U.S. Air Force for rapid runway repair (RRR). Ensures FOD mitigation and maintains operational readiness for high-impact landings.
  • Highways & Bridge Infrastructure: DOT-approved for rapid header and joint replacement. Machine-dispensed systems minimize lane closures, allowing semi-truck traffic to resume in minutes.
  • Industrial & Logistical Hubs: The premier choice for warehouse floors and loading docks, standing up to the constant stress of hard-wheeled forklift traffic.

Field-Proven Performance: CALTRANS Case Study

The California Department of Transportation (CALTRANS) relies on GeoSet Rapid Load-Bearing Concrete Repair Slurry for high-stakes bridge deck maintenance. On the El Cajon OH DR 57-362 project, GeoSet provided an immediate structural solution for bridge header repair. Semi-truck traffic resumed just 30 minutes post-application.
