Polyurethane injection resin

Q: What is Polyurethane Injection Resin, and how does it work?

Polyurethane Injection Resin is a high-performance, two-component or single-component resin designed to seal cracks, stop water leaks, and reinforce concrete structures . It reacts with water to form a flexible or rigid waterproof seal , depending on the formulation. This makes it ideal for structural repairs, leak sealing, and waterproofing applications .

Q: Where can ibeam’s Polyurethane Injection Resin be used?

Our high-quality Polyurethane Injection Resin is ideal for: Sealing cracks & joints in concrete walls & basements – Prevents water ingress. Tunnels & underground structures – Provides long-lasting waterproofing. Bridge decks & infrastructure repairs – Strengthens and stabilizes cracks. Dams & reservoirs – Stops water leakage in high-pressure environments. Sewage treatment plants & marine structures – Resists harsh chemicals and moisture.

Q: What are the benefits of using ibeam’s Polyurethane Injection Resin?

Using Polyurethane Injection Resin offers multiple advantages: Expands to seal cracks completely – Provides a watertight barrier. Flexible or rigid options available – Adapts to structural movement. Fast-curing & high adhesion – Reduces downtime in repair projects. Resistant to chemicals & corrosion – Ensures long-term durability. Suitable for wet & dry conditions – Works even in active water leaks.

Q: How is Polyurethane Injection Resin applied?

Id entify the crack or leakage area – Ensure the surface is clean and accessible. Drill injection ports along the crack – Space them evenly for full coverage. Inject the polyurethane resin – Use a low or high-pressure injection pump . Allow the resin to react & expand – It will fully seal the crack within minutes. Remove the ports & finish the surface – Ensure a smooth, sealed finish.

Q: How long does Polyurethane Injection Resin take to cure?

Initial reaction time : 30 seconds to 10 minutes , depending on the formulation. Full cure time : 24 hours for maximum strength and waterproofing.

Q: Can Polyurethane Injection Resin be used in actively leaking structures?

Yes! Our fast-reacting polyurethane resin is specifically designed to seal cracks in actively leaking walls, tunnels, and underground structures , ensuring complete waterproofing.

Q: What is the difference between flexible and rigid polyurethane resins?

Flexible polyurethane resin : Expands and contracts with structural movement, making it ideal for expansion joints and dynamic cracks . Rigid polyurethane resin : Forms a solid, non-flexible barrier, best for permanent structural repairs .

Q: Is ibeam’s Polyurethane Injection Resin environmentally friendly?

Yes! Our low-VOC, solvent-free formulation ensures safe and eco-friendly applications while maintaining superior performance.

Description

Comtech Pure LV is a single component polyurethane injection resin with low viscosity properties; when it is cured it formed impermeable flexible seal.

TYPICAL PROPERTIES:

Colour : Transparent yellow liquid.
Density: 1 g/cm³
Viscosity : 200Mpa.S @ 25ºC

AREA OF APPLICATION:

Hair cracks where very low viscosity injection resin is needed to allow penetration.
Moving cracks where Flexibility is required to withstand differential movements.
To be used in conjunction with Comtech Seal PU1, the high foaming expansion of Comtech Seal PU1 can stop the flowing water then Comtech Pure LV can be used as impermeable permanent seal.
Wide gaps where it needs to be sealed with stable seamless seal.

ADVANTAGES:

Forms a permanent sealing with high strength in the crack or joint.
Fast reacting impermeable seal.
Penetrates deep in fine cracks.
Non toxic when contacted with drinking water.
Can be used in dry and wet cracks.
Excellent adhesion to mineral construction materials (such as Concrete, cement, brick), metal and certain plastics
It is chemically resistant against water, weak acids and alkali, mineral oils, fungus and bacteria, ground water, sea water and petroleum products.

APPLICATION METHOD:

Clean surfaces.
Drill injection holes.
Insert injection packers.
Flush crack, if necessary.
Injection using single-component grouting equipment.
Cleanup.

STORAGE & PACKING: 4 & 10L tin.

Product should be stored in a dry shaded area, protected from breakage, deterioration and contamination. The shelf life is up to 12 months in un-opened condition and if stored as per recommendation.
