3. Extreme Performance:
2700% Foaming and 34MPa Compressive Strength
Description:
RUTH IP-12 is a premium, single-component oil-based hydrophobic polyurethane grout (OPU). Unlike hydrophilic agents that absorb water, IP-12 reacts aggressively with water to expand and cure into a rigid or semi-rigid hydrophobic polyurethane foam.
Designed for extreme conditions, this expanding polyurethane grout provides an immediate water stop injection foam barrier against high-pressure gushing leaks. Because it is hydrophobic, the cured foam maintains its dimensional stability and will not shrink even in dry environments, making it the superior choice for soil injection grouting and structural void filling.
Key Features & Benefits
High-Pressure Water Cut-Off: Rapid expansion (up to 25x-30x) effectively blocks gushing water in seconds.
Dimensional Stability (Non-Shrink): Cures into a chemically stable hydrophobic foam that retains its volume through wet/dry cycles, essential for long-term durability.
High Strength Support: The cured rigid foam provides excellent compressive strength, making it suitable for polyurethane foam concrete repair and stabilizing loose soil.
Deep Penetration: Low viscosity allows the hydrophobic polyurethane injection grout to penetrate fine hairline cracks before expanding.
Versatile Application: Compatible with RUTH’s single-component injection grouting machines.
Primary Applications
RUTH IP-12 is engineered for heavy civil engineering and geotechnical applications:
Concrete Lifting & Stabilization: Ideal for polyurethane foam injection concrete lifting (slab jacking) and poly foam leveling to correct sinking foundations.
Soil Injection Grouting: Used to stabilize loose soil and fill voids behind concrete structures (polyurethane injection foundation repair).
High-Flow Leak Sealing: Stopping massive water ingress in dam crack repair injection projects, tunnels, and subway stations.
Sea Wall & Marine Repair: The hydrophobic nature makes it resistant to washout, perfect for sealing leaks in seawalls and marine structures.
Infrastructure Repair: Filling large voids and preventing settlement in highways and airport runways.

Why Choose RUTH IP-12?
Engineered for Geotech: We understand the needs of foundation repair contractors. Our foam provides the lift and stability required for slab jacking projects.
Supply Chain Security: As a manufacturer with 5,000 tons annual capacity, we offer bulk pu foam grouting material at competitive factory-direct prices.
Complete Injection Solutions: RUTH supplies the full ecosystem, including grout injection kits, high-pressure pumps, and durable steel injection packers capable of withstanding the pressures required for hydrophobic injection.
FAQ: Why Use Hydrophobic Grout?
Q: Why choose Hydrophobic IP-12 over Hydrophilic grouts?
A: Hydrophobic polyurethane repels water and cures into a rigid foam that does not shrink when the surrounding area dries out. This makes IP-12 the only correct choice for soil injection grouting, concrete lifting, and stopping leaks where the water level fluctuates (wet/dry cycles). Hydrophilic grouts may shrink and lose their seal if they dry out.
Quality Control / Test Methods
RUTH Quality Assurance: How We Test At RUTH, consistency is our promise. Every batch of our Hydrophobic Polyurethane Grout undergoes rigorous testing before shipment.
Here is our standard lab protocol for ensuring non-shrink performance
Test Method: Curing & Rise Time Determination
Introduction
Testing the curing and rise time is essential to determine how Hydrophobic Polyurethane Grout (Oil-based PU) will behave in real-world applications like high-pressure leak sealing or soil stabilization. This test confirms the reaction speed and the foam's structural stability.
1. Sample Preparation
Using a precision balance, weigh 20g (±0.1g) of Hydrophobic Polyurethane Grout (often referred to as Oil-based PU) into a 250ml beaker or disposable paper cup.
2. Catalyst/Water Addition
Add a minimum of 1.0g of water to the cup (approximately 5% of the resin's weight). (Note: Since this is a hydrophobic material, water acts as the blowing agent to initiate the expansion reaction).
3. Agitation & Mixing
Immediately upon adding water, stir the mixture rapidly and vigorously.
Mixing Duration: Continue stirring for approximately 15 to 25 seconds.
Visual Cue: The mixture is considered uniform when the oil-based resin and water combine to form a pale yellow, frothy emulsion state.
4. Recording Reaction Time
Start: Start the stopwatch the exact moment the water is introduced to the resin.
End: Observe the rising foam. Stop the stopwatch when the hydrophobic foam completely stops rising (reaches maximum volume).
Result: This duration is recorded as the Full Rise Time (often used to indicate the complete curing time for field applications).
5. Stability Observation
Allow the cured foam sample to sit at room temperature for 10 hours.
Check for Shrinkage: Inspect the foam structure. High-quality Hydrophobic Polyurethane Grout should remain rigid and show no signs of shrinkage. This "non-shrink" property is critical for applications like polyurethane foam injection concrete lifting and filling voids, ensuring long-term structural support.
