Mountain Grout Gel Foam: A Technical Overview
Mountain Grout Gel Foam is a single-component, hydrophilic polyurethane resin engineered to react with water and create either an expansive foam or an elastic gel. This adaptability ensures effective leak sealing under a wide range of conditions. Designed for active water inflow repairs, Gel Foam penetrates fine cracks, expands up to 25×, and bonds strongly to concrete substrates. The cured material remains flexible and resilient under continuous moisture, making it ideal for remedial and infrastructure waterproofing applications.
25×
Expansion with water to chase active leaks
Core Features & Specifications
- Hydrophilic polyurethane resin reacts with water to form foam or gel depending on moisture conditions.
- Single-component pumping system simplifies setup and reduces labour.
- Penetrates fine cracks and voids with low viscosity for thorough sealing.
- Expands up to 25× to chase leak pathways and form a watertight barrier.
- High elongation cured gel accommodates substrate movement without loss of seal.
- 100% solids, no VOCs, safe handling and environmentally responsible.
- Maintains performance under constant water exposure—ideal for tunnels, dams, and wastewater structures.
The Mountain Grout Gel Foam Advantage
- Versatility: forms either foam or gel to address varying water conditions.
- Reliability: cured gel/foam is inert, non-toxic, and durable under wet service.
- Ease of use: single-component pumping streamlines mobilisation on active leak sites.
- Penetration power: low viscosity reaches micro-cracks for comprehensive sealing.
- Environmental confidence: solvent-free, non-flammable, and compliant with safety standards.
Proactive Troubleshooting
Scenario: Insufficient water in the crack
Potential Outcome: Incomplete gel/foam reaction and weak seal.
Adheseal Best Practice: Pre-wet dry sections lightly to guarantee consistent water contact for uniform gel development.
Scenario: Excessive water flow washing out resin
Potential Outcome: Displacement of material before reaction, leaving leak unsealed.
Adheseal Best Practice: Use staged injection and porting downstream-to-upstream to build a gel curtain that resists washout.
Applications in Practice: Trade Scenarios
For Remedial Waterproofers (On-site Applicator): Stopping fast leaks in basements
The Professional's Challenge
Active water is entering under pressure, making crack repairs difficult with cementitious fillers.
The Adheseal Solution: Engineered Certainty in Practice
Inject Mountain Grout Gel Foam to react directly with the leak path, expanding into voids and forming a watertight gel/foam barrier that remains elastic under ongoing inflow.
Best Practice Note
Stage port injections to ensure complete coverage along the leak path; observe for backflow to confirm sealing.
For Asset Maintenance Crews (Specifier/Engineer): Manhole infiltration
The Professional's Challenge
Groundwater ingress through annular spaces compromises sewer network capacity and increases treatment costs.
The Adheseal Solution: Engineered Certainty in Practice
Gel Foam’s hydrophilic reaction forms a flexible, inert curtain around penetrations, preventing re-infiltration even under continuous head pressure.
Best Practice Note
Inject circumferentially around penetrations and monitor for reduction in inflow; confirm by flow meter readings if possible.
Frequently Asked Questions
What makes Gel Foam different from Flexible resin?
Gel Foam is hydrophilic and reacts readily with water to form either a gel or foam. Flexible is hydrophobic and forms closed-cell foam that resists shrinkage. Gel Foam is preferred where continuous water contact is expected.
How much does Gel Foam expand?
The resin expands up to 25× its original volume depending on water availability, enabling it to fill voids and follow leak pathways effectively.
Is the cured resin flexible?
Yes. The cured gel exhibits high elongation, allowing it to accommodate substrate movement and dynamic joint behaviour without losing watertightness.
Can it be used in potable water structures?
Yes. Mountain Grout Gel Foam cures to an inert, non-toxic seal suitable for structures in contact with water once cured.

Applying Mountain Grout Gel Foam: Enhanced Protocols & Best Practices
-
Surface & Leak Assessment
Map crack or joint water inflow. Install injection ports from lowest point upwards to capture leak path. Lightly pre-wet dry zones.
Pro Tip: Stage injection zones to prevent resin bypass. -
Injection Preparation
Pump Gel Foam as a single component. Ensure resin temperature is 15–30 °C for optimal handling.
Pro Tip: Use a reliable injection pump with pressure control for consistency. -
Injection & Monitoring
Inject slowly until grout flows from adjacent port or water flow stops. Resin reacts with water to form foam or gel depending on availability.
Pro Tip: Maintain steady flow; do not over-pressurise to avoid resin washout. -
Post Injection Checks
Confirm water cut-off. Remove ports and patch holes once cured. Inspect sealed area for re-infiltration under water head.
Pro Tip: Recheck after rainfall or system surges to verify long-term performance.
Limitations & Safety
Product Limitations
Requires water presence to react; in dry substrates pre-wetting is mandatory.
Not a structural repair product; intended for leak sealing only.
Expansion ratio and gel formation vary with water quantity; site testing is recommended.
Safety & Handling Requirements
Personal Protective Equipment
Wear nitrile gloves, chemical goggles, and protective clothing. Avoid direct skin or eye contact.
Ventilation
Use in well-ventilated areas. Follow confined-space entry procedures where relevant.
Fire & Handling Precautions
Resin is non-flammable but standard chemical handling practices apply. Store sealed containers away from extreme heat.
Emergency First Aid
Eyes: Rinse with clean water for several minutes; seek medical advice.
Skin: Wash with soap and water; remove contaminated clothing.
Inhaled: Move to fresh air; consult medical professional if symptoms persist.
Swallowed: Rinse mouth. Do not induce vomiting. Seek medical attention immediately.
Mountain Grout Gel Foam Application Guide
Concrete Cracks (Active Leaks)
Surface Preparation
Drill and install injection ports along the crack line. Clean surrounding surfaces to contain grout. Pre-wet very dry sections to guarantee water contact for resin activation.
Primer Requirements
Primer not required
Hydrophilic resin bonds directly to moist concrete substrates.
Construction Joints
Surface Preparation
Locate leak paths along joint line. Port spacing should be close enough to ensure grout curtain forms. Ensure joint faces are free from debris.
Primer Requirements
Primer not required
Focus on correct water contact and port placement.
Manholes & Penetrations
Surface Preparation
Install circumferential port pattern around pipe or penetration. Clean surfaces to secure ports. Ensure annular spaces are moist to trigger resin reaction.
Primer Requirements
Primer not required
Injection relies on moisture activation, not priming.
Tunnels & Dams
Surface Preparation
Establish port layout across seepage areas. Clean to remove loose laitance and ensure secure seating of packers. Maintain moisture presence for activation.
Primer Requirements
Primer not required
Gel Foam is designed for direct injection into wet concrete substrates.
