Logic UW

High-Performance Epoxy Injection System for Structural Crack Repair, Sealing and Waterproofing

Logic UW is a professional epoxy injection system designed for the permanent repair and sealing of cracks in concrete and masonry structures exposed to moisture, water ingress, and hydrostatic pressure. Using micro- and pico-scale penetration technology, it reaches deep into capillary pores and microcracks beyond the reach of conventional repair materials. After curing, Logic UW forms a durable, water-insoluble polymer matrix that restores structural continuity, seals water pathways, and reinforces the repaired area. Suitable for wet substrates and demanding underground environments, it delivers reliable waterproofing and structural protection with up to 20 years of performance.

Reliable Protection Against Water Ingress

  • Forms a permanent barrier against water penetration
  • Effective under hydrostatic pressure conditions
  • Suitable for active water leakage environments
  • Helps prevent moisture-related deterioration
  • Ideal for basements, tunnels, foundations, and underground structures

Restoring Structural Integrity

  • Bonds separated concrete and masonry elements
  • Restores structural continuity across repaired cracks
  • Supports load transfer within the repaired structure
  • Improves the stability of weakened structural components
  • Provides durable adhesion and long-term performance

Reaching Microcracks Beyond the Surface

  • Penetrates deep into capillary pores and microcracks
  • Enables sealing beyond the reach of conventional repair materials
  • Fills hidden crack networks within the substrate
  • Provides strong internal bonding and stabilization
  • Creates a long-lasting waterproof and structural barrier

Deep Crack Penetration Technology

Logic UW utilizes micro- and pico-scale penetration technology to reach deep into concrete pores, capillaries, and microcracks that are inaccessible to conventional repair materials. The low-viscosity epoxy formulation penetrates hidden pathways within the substrate, enabling effective sealing, waterproofing, and structural bonding throughout the crack network. Once cured, it forms a durable, water-insoluble polymer matrix that restores structural continuity while permanently blocking water ingress. Suitable for wet substrates and hydrostatic pressure conditions, Logic UW delivers high mechanical and chemical resistance, long-term durability, and reliable performance for infrastructure, commercial, industrial, and restoration projects. The solvent-free, low-emission formulation provides up to 20 years of protection when properly applied.
