ADVANTAGES

Rapid Reaction:

Reacts quickly with water, expanding
and solidifying.

High expansion rate

This product features a high expansion rate and is non-shrinking, capable of forming
solid foam material up to 30 times its original volume.

Strong Adhesion:

Provides strong adhesion to
substrates and excellent chemical resistance.

Strong permeability:

Low viscosity, large penetration radius, capable of penetrating fine cracks and pores, with strong adhesion to the substrate, ensuring long-lasting repair effects.

Customization is available for product forming rate, packaging design, and package sizes.

Note:

1..To ensure sufficient time for smooth operation, this product expands to its maximum state in about 20 minutes at room temperature. If faster speed is required, an accelerator can be added, which can be purchasedseparately from the manufacturer

2.The ambient temperature during application should beabove 0°C, as low temperatures may affect the reactionand curing speed.

3.Ensure adequate ventilation and keep away from anyignition sources during application. Open flames must not be used in the surrounding work area before the materialhas cured

4.Immediately after use, machine must be thoroughly cleaned with a cleaning agent until completely clean.

Construction Process of PU Injection Grout

图片1 拷贝

Pre-construction Preparation

Surface Preparation: Clear oil, moss, loose concrete and debris. Chisel or brush crack areas for firm base.

图片2 拷贝

Drilling and Hole Cleaning

Hole Layout & Positioning: Pinpoint leakages including cracks, joints and voids. Stagger injection holes 3-5cm from crack sides.

图片3 拷贝

Packer Installation

Insert packers into holes and fasten firmly with wrench till rubber rings seal tightly.
Optional: Coat cracks with quick-set mortar to avoid slurry leakage during grouting.

图片4 拷贝

Grouting Operation

Lead ofEquipment Inspection: Verify grouting machine, gauge and hoses intact, connect power safely.
Grout Feeding: Fill polyurethane grout into machine hopper.

Packer Removal

Packer Removal: After 24 hours (or upon confirmation that the grout has fully cured), unscrew or knock off the packers using a wrench.

Hole Sealing

Fill and level the injection holes with cement-based plugging material, epoxy mortar, or waterproof mortar to ensure a smooth and even substrate surface.
