Sika Injection-306
Ultra-low-viscosity elastic polyacrylic resin for permanent crack, joint and membrane sealing
Product Overview
Sika Injection-306 is an elastic, three-part polyacrylic injection resin used for permanent watertight sealing in demanding ground and structural conditions. Its very low viscosity lets it penetrate the finest cracks, voids and gel-injection zones, while an adjustable reaction time — controlled by accelerator dosage and temperature — gives applicators precise control from rapid sets to longer working windows. It is well suited to repairing damaged waterproofing membranes, sealing construction joints in water-saturated soil through external (curtain) injection, sealing water-bearing cracks, and forming sealing barriers in damp or wet ground. Supplied as resin, accelerator and hardener components mixed 1:1 by volume, it is a flexible solution for specialist waterproofing teams. Space Arc Engineering, an authorized Sika distributor in India, supplies Sika Injection-306 to contractors handling below-ground and curtain-injection waterproofing.
Features & Benefits
- Extremely low viscosity penetrates hairline cracks, soil voids and gel zones
- Reaction time adjustable from about 8 to 50 minutes for full control on site
- Cures to an elastic gel/seal that tolerates movement in saturated ground
- Ideal for curtain (external) injection behind structures and behind membranes
- Solvent-free, three-part system designed for water-bearing applications
- Long 12-month shelf life in sealed original packaging for project planning
Technical Highlights
| Coverage | Consumption depends on crack and soil-void volume and the injection method; very low viscosity supports deep penetration — refer to TDS for estimating. |
| Strength | Cures to an elastic polyacrylic gel/seal for permanent watertightness; for mechanical values refer to TDS. |
| Performance | Very low viscosity of about 3–11 mPa·s at 20 °C with adjustable reaction time of roughly 8–50 minutes; pot life is reaction time minus about 10 minutes. |
| Application Conditions | Apply between +5 °C and +40 °C (ambient and substrate); mix premix A to hardener solution B at 1:1 by volume and tune accelerator for the required reaction time. |
| Packaging | Supplied as Component A (2 × 8.0 kg), accelerator (1 × 1.0 kg), hardener powder (4 × 40 g), with extra accelerator (4 × 1 kg) available. |
Applications
- Curtain (external) injection sealing of construction joints in water-saturated soil
- Repair and re-sealing of damaged waterproofing membranes behind structures
- Permanent sealing of water-bearing cracks and voids in below-ground concrete
- Forming soil-stabilising sealing barriers in damp and wet ground conditions
- Waterproofing tunnels, shafts and basements where ground water pressure is present

Frequently Asked Questions
What is Sika Injection-306 used for?
It is an elastic polyacrylic injection resin for permanently sealing water-bearing cracks and joints, repairing damaged waterproofing membranes, and forming sealing barriers in wet ground. Its low viscosity makes it ideal for curtain (external) injection.
Can you adjust the reaction time of Sika Injection-306?
Yes. The reaction time is adjustable from about 8 to 50 minutes depending on accelerator dosage and temperature, and the usable pot life is roughly the reaction time minus 10 minutes. This lets applicators tune sets to the situation.
How is Sika Injection-306 mixed?
The premix (Component A) and hardener solution (Component B) are combined at 1:1 by volume, with the accelerator dosed to set the reaction time. It should be applied between +5 °C and +40 °C. Follow the TDS for full mixing detail.
How does Sika Injection-306 differ from PU injection resins?
It is a very low-viscosity polyacrylic gel resin that penetrates extremely fine cracks and soil voids and is especially suited to curtain injection in saturated ground, whereas PU resins like Sika Injection-201 IN are typically injected directly into cracks.
