SIKA INJECTION 101IN(POLYURETHANE INJECTION) 5KG,LIQUID

About SIKA INJECTION 101IN(POLYURETHANE INJECTION) 5KG,LIQUID

 91 000 74051 Sika Injection-101 IN is a two-component, water-reactive polyurethane resin that foams when it contacts water, forming a flexible, hydrophobic closed-cell foam. Its designed for stopping running water leaks, filling cracks and joints in concrete under hydrostatic pressureideal for foundations, tunnels, water tanks, retaining walls, basements etc. 
Key Features & Benefits
Low viscosity resin for deep penetration into cracks & voids. Produces a flexible, closed-cell foam that is hydrophobic and resists future water ingress. Reacts with water to foam up to ~40 its original volume. Fast gel time (~10 seconds) allowing quick sealing. Comes pre-batched (5 kg kit: 4.5 kg base + 0.5 kg catalyst) for ease of use. Suitable for use under hydrostatic pressure.
Q1. How is Sika Injection-101 IN applied?Clean the crack/joint (remove loose particles, oil, wax).Seal around the injection packer (if needed) to avoid resin escaping.Mix Part A (base) and Part B (catalyst) at ~90:10 ratio (or adjust within allowed limits for reaction time). Use injection pump to inject resin at low pressure, allow foam to expand and seal.Once set, clean away excess.Q2. What is gel time & cure time?Gel time is about 10 seconds at ~25-30 C. Tack-free / initial curing takes ~2 hours. Q3. What are the packaging & storage details?Comes as a pre-batched 5.0 kg kit: 4.5 kg base (Part A) + 0.5 kg catalyst (Part B). Store in sealed, unopened containers at 5-30 C. Shelf-life ~12 months. Q4. Is it safe for potable water or for use in drinking water tanks?It is hydrophobic and resistant to fungi/microorganisms. But products like this are generally for structural waterproofing, not for direct contact with potable water without checking specific approvals. Always check local PDS / safety data. Q5. What surface temperature and ambient conditions are needed?Both ambient and substrate temperatures should be between +10 C to +40 C. Q6. How much does it cost (rough estimate)?Please Visit or Contact CivilizeMart More Information

Effective Water-Stop Technology

SIKA INJECTION 101IN utilizes advanced polyurethane chemistry for rapid and reliable water-stopping. Upon contact with water, it rapidly expands to form a dense foam, efficiently sealing cracks and voids. Its quick reaction time ensures minimal downtime and fast restoration, making it suitable for urgent leak repairs in concrete or masonry structures.


Versatile Application in Crack Repair

Engineered for ease of use, SIKA INJECTION 101IN's single-component, low-viscosity formula allows deep penetration into fine cracks. It is widely used in industrial, commercial, and residential settings for water leakage control and crack injection. Its adaptability ensures compatible application for both temporary and longer-term solutions.
