Polyurethane injection foam

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

Polyurethane Injection Foam is a high-performance, expanding foam sealant used for sealing cracks, stopping water leaks, and stabilizing concrete structures . It reacts with moisture to expand and form a flexible, watertight seal , making it ideal for structural repairs and waterproofing applications .

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

Our high-quality Polyurethane Injection Foam is ideal for: Sealing cracks in concrete walls & foundations – Prevents water ingress. Tunnel & underground structure repairs – Provides long-lasting sealing. Bridge & highway maintenance – Stabilizes cracks and weak points. Basement & retaining walls – Ensures waterproofing and leak prevention. Dams & water treatment plants – Stops water seepage in high-moisture environments.

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

Using Polyurethane Injection Foam offers multiple advantages: Expands to fill voids & cracks completely – Provides a durable seal. Highly flexible & waterproof – Adapts to structural movement. Fast-curing & high adhesion – Reduces downtime in repair work. Chemical & corrosion-resistant – Ensures long-term protection. Suitable for wet & dry conditions – Works even in active water leaks.

Q: How is Polyurethane Injection Foam applied?

Identify the crack or leak – Ensure the surface is clean and dry. Drill injection ports – Place ports along the crack for even distribution. Inject the polyurethane foam – Use a high-pressure injection pump. Allow the foam to expand & cure – The foam will seal the crack completely. Remove injection ports & finish – Ensure a smooth surface after curing.

Q: What is the curing time for ibeam’s Polyurethane Injection Foam?

Initial set time : 3-10 minutes. Full cure : 24 hours , depending on temperature and moisture conditions.

Q: Can Polyurethane Injection Foam be used for active water leaks?

Yes! Our fast-reacting polyurethane foam is designed to seal cracks even in actively leaking structures , making it ideal for waterproofing basements, tunnels, and underground structures .

Q: What is the difference between single-component and two-component polyurethane foams?

Single-component foam : Expands with atmospheric moisture, best for general sealing. Two-component foam : Expands faster and is better suited for high-pressure injection repairs .

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

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

Description

Comtech Seal PU1 is a single component polyurethane injection resin with low viscosity properties; it reacts with water forming a semi rigid hydrophobic seal.

TYPICAL PROPERTIES:

Colour : Transparent brown liquid.
Free expansion: up to 3500 %
Density: 1.02-1.1 g/cm³
Viscosity : 250Mpa.S @ 25ºC

AREA OF APPLICATION:

Water sealing of cracks and big gaps in walls, floors, concrete constructions. It has the property of fast reacting to semi rigid PU foam once contacted with water.

ADVANTAGES:

Forms a permanent sealing with high strength in the crack or joint.
Fast reacting semi rigid PU foam used as a water stop for sealing of leakages or to stop active water leaks with a high flow and/or high hydrostatic pressure.
Penetrates deep in fine cracks.
Does not shrink after curing.
Non toxic when contacted with drinking water.
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
Injecteion using single-component grouting equipment.
Cleanup
