SIKA (5KG) TWO COMPONENT POLYURETHANE INJECTION FOAM RESION FOR WATER LEAKAGE (INJECTION - 101 IN)

About SIKA (5KG) TWO COMPONENT POLYURETHANE INJECTION FOAM RESION FOR WATER LEAKAGE (INJECTION - 101 IN)

 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

Powerful Water Sealing Performance

SIKA Injection Foam swiftly reacts with water to form a flexible, expansive foam, effortlessly sealing water leakages. It is ideal for applications in basements, tunnels, shafts, and construction joints. Its rapid foam expansion ensures even hard-to-reach cracks are filled and sealed, helping to maintain the structural integrity of buildings and infrastructure.


Simple Application Process

The product's two-component system is mixed in a 1:1 ratio and injected into the targeted area using specialized injection pumps. With an initial curing time of seconds to minutes and a full cure in approximately 24 hours, the process is efficient, allowing for minimal downtime during repairs or maintenance.


Reliable and Safe

SIKA's polyurethane injection foam boasts non-toxic properties once fully cured, and is designed with high purity and industrial grade formulation. The foam does not corrode structural materials and has minimal odor, making it suitable for use in occupied buildings and sensitive environments. Proper handling during application ensures best results and user safety.
