Key Features & Advantages

  • Exceptional hydroscopic properties and flexibility
  • Superior water absorption and displacement capabilities
  • Strong adhesion and cohesion with a wide range ofsubstrates
  • High resistance to diffusion and aggressive groundwater constituents.
  • High alkaline pH (>9.0) for enhanced durability.
  • Unlimited resistance to aging; remains fluid over time.
  • Withstands extreme temperatures (-25°C to +100°C).
  • UV-resistant and non-degradable under sunlight.
  • Suitable for soft, acidic water (low pH, aggressive to concrete).
  • Can be applied to weak substrates (cohesion/tensile strength <1.5 N/mm²).
  • Effective on wet, moist, or fully submerged surfaces.
  • Compatible as a carrier for additives (micro-cement, rubber powder, zeolite).
  • Non-aggressive to bituminous surfaces; fully compatible.
  • Environmentally safe and composed of natural materials.

Application Guidelines

  • Method
    Pressure injection (2 – 200 bar) using standardinjection pumps
  • Surface preparation
    Suitable for use on wet, moist, orwater-submerged surfaces; no need for substrate to be dry
  • Installation
    Only to be performed by EurasTechnology-approved contractors
  • Post-application
    Water tightness must be verified and approvedaccording to project specifications
01
Assessment

Our experts identify water ingress points and determine optimal injection locations

Installation

Strategic drilling of injection holes and placement of packers in the affected areas

02
03
Injection

High-pressure application (50-200 bar) forces gel into voids and cracks

Displacement

The gel actively pushes out existing water while filling all spaces

Permanent Protection

The gel remains permanently flexible, creating a lasting waterproof barrier

The EURAS Advantage

Why Choose EURAS® Gel Core Over Conventional Solutions

Unlike competitors who merely block water entry points, our hydraulic displacement medium permanently removes water from the structure, addressing the root cause of leakage.

While polyacrylic gels from competitors can deteriorate to acidic pH levels as low as 1.20 (proven by Deutsche Bahn testing), our formula maintains a stable alkaline pH of 8.50-9.00, with specialized formulations (Euras Type 10+) exceeding pH 10.30.

Our mineral-based composition actively protects reinforcement steel from corrosion, unlike competitor products that may accelerate corrosion through pH deterioration.

As a single-component system, our product eliminates the mixing errors and inconsistencies common with multi-component competitive systems.

Our specialized Type -20 formulation withstands temperatures down to -24°C without degradation, outperforming conventional waterproofing materials in extreme conditions.

Built primarily from inorganic minerals, our product poses no environmental hazards to groundwater, unlike many polymer-based competitor systems.

The injection process creates temporary overpressure that tests surrounding structures and identifies additional leakage points that competitive systems would miss.

Uniquely enables creation of injection mortars that displace water without dissolving or mixing with it, maintaining compressive strength almost identical to conventional mortars.

Our Type γ formulation has been tested to withstand 12,500 kGy without loss of insulating ability, making it suitable for nuclear applications where competitive products would degrade.

Successfully implemented in hydroelectric power plants, tunnels, and marine environments with water pressure exceeding 55 bar, where competitor systems have previously failed.

100% Guaranteed Satisfaction

Stop Water in its tracks

Engineered to provide permanent solutions for water leaks, we are so confident in the durability of our product that if any treated leak recurs, we will return to fix it at no additional cost.
This guarantee is our unwavering commitment to excellence and to ensuring the long-term reliability of your infrastructure. Choose our sealing gel, and rest easy knowing you've opted for a solution that we stand behind—for life.
