Logic UW

High-Precision Injection Solution for Crack Repair

Logic UW is an advanced injection system designed to repair and seal cracks in concrete structures exposed to moisture and hydrostatic pressure. Applied through controlled drilling and injection, it restores structural integrity in basements, tunnels, lift shafts, and foundations. Unlike conventional repair mortars, Logic UW is effective even on wet substrates and under pressurized water. Safe for sensitive environments, including drinking water systems and historical buildings, it ensures reliable protection without harmful additives or chemical reactions. Backed by a 20-year guarantee, Logic UW is the trusted choice for long-lasting structural repair and protection.

High-Performance Sealing

  • Injection process fills cracks at 25 cm intervals with precision
  • Stops water ingress even under pressure in walls, floors, and ceilings
  • Proven effectiveness in basements, tunnels, shafts, and underground works

Structural Strengthening & Bonding

  • Provides durable adhesion between walls, slabs, and foundations
  • Reinforces historic and modern concrete without damaging materials
  • Improves performance of weakened or porous building elements

Safe & Durable Application

  • Seals micro- and capillary cracks undetectable by conventional mortars
  • Penetrates deeply into pores for permanent structural repair
  • Free of solvents or acids, safe for monuments and potable water areas

Next-Generation Protection with Pico Technology

Logic UW introduces a new generation of crack injection technology based on Pico Technology – ultra-fine particles smaller than nanoparticles. This enables the resin to reach hidden capillaries and micro-cracks where standard products fail, blocking invisible water pathways at their source. The epoxy formulation cures into a permanent, water-insoluble matrix that maintains stability even in high-pressure environments. Environmentally neutral and highly resistant, Logic UW reduces maintenance demands, extends the lifespan of structures, and ensures long-term safety for infrastructure and restoration projects. This injection waterproofing system defines precision and durability in modern construction.

Applications of Logic UW

  • Crack repair in floors, walls, and ceilings
  • Sealing water ingress in tunnels and underground facilities
  • Cold joint and construction interface sealing
  • Water leakage in lift shafts
  • Moisture problems in historical buildings and monuments
  • Infrastructure repair and reinforcement under hydrostatic pressure

Step-by-Step Guide

  1. crack injection steps concrete waterproofing guide Step 1: Inspect leaks and cracks; remove loose material.
  2. injection packer installation 45 degree drilling method Step 2: Drill at 45°, ~12.5 cm offset, 25 cm spacing (cross pattern).
  3. resin injection 60 bar mix Logic UW A+B ratio Step 3: Insert injection packers firmly into all holes.
  4. sealing basement cracks tunnel waterproofing injection Step 4: Mix Logic UW A+B at a 1:1 ratio.
  5. lift shafts leak repair cold joint crack sealing Step 5: Inject resin with machine at approx. 60 bar until saturated.
  6. hydrostatic pressure repair mortar sealing after injection Step 6: After curing, remove packers; seal holes with mortar.
