Percol Concrete Welder: Machine-Dispensed Structural Restoration

High-Volume Fissure Welding & Sub-Slab Stabilization

Percol Concrete Welder is a professional-grade, ultra-low viscosity urethane polymer engineered for large-scale infrastructure restoration. Optimized for use with Vari-Flo plural-component dispensing equipment, this fast-reacting system is designed for high-output highway, bridge, and industrial projects where rapid succession repairs are required. Because of its water-thin consistency, Concrete Welder gravity-feeds into hairline cracks and flows underneath spalled concrete, effectively "welding" broken structures and sealing the base against moisture-driven erosion and void formation.

Key Industrial Performance Attributes

  • High-Throughput Efficiency: Designed specifically for machine application, allowing contractors to complete extensive repairs with minimal traffic or operational closures.

  • Deep Matrix Penetration: The ultra-low viscosity allows the polymer to penetrate the tightest fissures, restoring the structural adhesive bond between broken concrete sections.

  • Base Stabilization: Flows into sub-slab voids to seal the base against water intrusion, preventing further erosion and "slab rocking" under heavy loads.

  • Aggressive Chemical Shield: 100% solids formulation provides a permanent barrier against hydraulic fluids, aviation fuels, salts, and antifreeze.

  • Multi-Substrate Versatility: While optimized for concrete structural restoration, this reactive resin is equally effective for technical asphalt welding applications.

  • Environmentally Responsible: Contains no solvents, is nearly odorless, and features low toxicity, making it suitable for both open-air highways and enclosed industrial environments.

Primary Industrial Applications

  • Large-Scale Highway Restoration: Rapid sealing of longitudinal and transverse cracks to extend pavement lifecycle.

  • Bridge Deck Fissure Welding: Deep-penetrating sealing to protect reinforcing steel from chloride-induced corrosion.

  • Industrial Warehouse Flooring: High-speed repair of spider cracks and spalls in high-traffic forklift zones.

  • Airport Apron Maintenance: Fuel-proofing and structural stabilization of high-load aviation concrete.

Technical Application Guidelines (Machine Applied)

Structural Crack & Spall Restoration

  1. Preparation: Ensure the area is clean and moisture-free. Use dry compressed air to clear fissures of debris.

  2. Aggregate Integration: For cracks 1/8" and wider, fill the void with clean, dry aggregate (ranging from 1/4" to 1" depending on depth).

  3. Machine Saturation: Utilizing the Vari-Flo pump, flood the aggregate-filled crack to grade with Percol Concrete Welder.

  4. Surface Finish: Immediately broadcast Concrete Topping Sand into the wet polymer to ensure an anti-skid, professional gray finish.
