Logic UW FLEX

Bio-Based Precision & Flexible Crack Injection

Logic UW FLEX is a next-generation injection system designed for high-precision crack repair in demanding infrastructure projects. With Pico Technology, its ultra-fine particles penetrate micro-capillaries, sealing even the smallest cracks. Unlike rigid mortars, it remains elastic, adapting to expansion, contraction, and vibration without re-cracking. Eco-friendly, water-resistant, and backed by a 20-year guarantee, Logic UW FLEX is the preferred solution for tunnels, bridges, stadiums, and other heavy-duty structures where precision, flexibility, and long-term durability are essential.

Next-Generation Protection with Pico Technology

Logic UW FLEX defines the future of crack repair by combining Pico Technology with flexible polymer chemistry. With particles smaller than nano, it penetrates deep into capillaries and hidden pores, sealing water pathways that traditional mortars cannot reach. Its elastic composition adapts to movement, vibration, and structural stress, ensuring cracks remain sealed under changing loads. Environmentally safe and solvent-free, Logic UW FLEX delivers lasting waterproofing and stability. This flexible waterproofing system is trusted for infrastructure where precision, adaptability, and sustainability are critical.

Applications of Logic UW FLEX

  • Cracks in tunnels and underpasses
  • Structural cracks in stadiums
  • Bridge cracks and expansion joints
  • Dilatation (Expansion) joints and cold joint sealing
  • Infrastructure exposed to vibration and heavy loads
  • Long-term waterproofing for critical structures

Step-by-Step Guide

  1. crack injection leak inspection Step 1: Inspect surface for leaks & cracks, remove excess material.
  2. surface preparation 45° drilling Step 2: Drill 45° holes at 12.5 cm height, 25 cm apart, cross pattern.
  3. 12.5 cm height 25 cm c/c spacing Step 3: Insert injection packers firmly into all drilled holes.
  4. cross-pattern drilling injection packers Step 4: Mix Logic UW Components A + B in 1:1 ratio.
  5. mix A+B 1:1 resin injection ~60 bar, Step 5: Inject resin with machine at approx. 60 bar until saturated.
  6. inject to saturation remove packers mortar seal Step 6: After curing, remove packers & seal holes with mortar.
