Use Mountain Grout Gel Foam for: Stopping active leaks in concrete cracks and joints; forming water-reactive gels or foams to restore watertightness in manholes, vaults, tunnels, dams, stormwater and wastewater assets.

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.

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.
