SikaFix-101 is a single-component polyurethane (PU) injection resin, solvent-free and low viscosity, that reacts and expands on contact with water to form a flexible closed-cell waterproof seal. Designed for injection sealing of active cracks, pipe penetrations, and honeycombing in tunnels, basements, and below-grade concrete structures.
Overview
SikaFix-101 is a single-component polyurethane resin injection material that reacts rapidly with water, expanding to form a flexible closed-cell foam seal that effectively stops water penetration. The product is solvent-free, non-flammable, non-toxic when cured, and compatible with salt water, making it suitable for various underground leak repair applications.
Features
- Fully waterproof — forms closed-cell flexible foam seal
- Permanently flexible — accommodates ongoing movement in active cracks
- Solvent-free, non-flammable — safe for confined space work
- Non-shrinking — fills completely and permanently
- Non-toxic when cured
- Reacts with salt water — suitable for marine environments
- Rapid reaction — foaming begins quickly on water contact
- Resistant to biological degradation and mild acids/alkalis
Applications
- Tunnel and utility passage leak injection
- Basement and underground car park crack sealing
- Below-grade concrete structure waterproofing
- Active crack and construction joint leak treatment
- Pipe penetration leak sealing
- Defective concrete filling (honeycombing, voids)
Why Choose SikaFix-101?
- Professional injection sealing — inject directly into water-bearing cracks; reacts and seals on contact
- Flexible seal — permanently flexible, won't crack with structural movement
- Harsh environment compatible — works in salt water and mild acid/alkali conditions
- Safe application — solvent-free, non-flammable, non-toxic when cured
- Sika quality — backed by a global leader in construction chemicals
Packaging
20 kg pail
Application Notes
- Injection requires high-pressure piston or twin-piston pump
- For wider cracks, pre-fill with open-cell foam soaked in SikaFix-101, then spray with water to activate
- Lower temperatures increase foaming time
- Material exposed to atmospheric humidity will gradually cure; use promptly after opening
- Clean tools with Sika Colma-Cleaner or Thinner C
- Expansion generates pressure; consider structural implications
