HCC Resins
The HCC resin range is a technical line developed entirely by our R&D&I team, designed to meet the specific demands of dams and hydraulic infrastructures. Their formulation is optimized to ensure adhesion, volumetric stability, penetration capacity and reliable performance even under adverse hydraulic conditions.
These resins significantly outperform conventional market products, offering precise and durable solutions for crack sealing, structural consolidation and leakage control in critical areas.
HCC Resins
HCC has its own range of epoxy resins developed entirely by our R&D&I team, specifically formulated for sealing cracks in structures requiring high mechanical performance, making them ideal for leakage sealing in dams and hydraulic infrastructures. These resins have been optimized to ensure high effectiveness under adverse hydraulic conditions, including flowing water, high pressures and complex crack geometries.
Their design responds to the need to intervene in critical points where precise penetration capacity, reliable adhesion to the substrate and long‑term volumetric stability are required. Their performance has been validated through internal and external testing, and their application on site has demonstrated high efficiency even in areas with difficult access or demanding structural requirements.
All our resins are CE‑marked and comply with the requirements of EN 1504‑5. We classify our resins according to viscosity, adhesion and flexibility, adapting each product to the specific pathology, crack opening and pressure or flow conditions.
