    Technical characteristics

    • Effective blocking of rising damp through a crystallization chemical barrier.
    • High penetration into the substrate (up to 16 mm in concrete according to Applus test), ensuring deep protection.
    • Compatibility with masonry, stone, and concrete walls, even in historic buildings.
    • High breathability thanks to macro-porous mortars and mineral finishes
    • Protection against salts and efflorescence, preventing aesthetic and structural degradation.
    • Hygrothermal stability: reduces thermal bridges and prevents condensation.
    • Weather-resistant finishes with mineral paints and water repellents
    • Compliance with European standards (UNE-EN 998-1, EN 1062-3, EN 1542) for mortars and coatings.

    Applications and advantages

    • Homes affected by rising damp in interior walls.
    • Historic facades and architectural heritage.
    • Basement and ground floor walls in contact with damp soil.
    • Restoration of walls with efflorescence and peeling.
    • Rehabilitation of commercial premises and public spaces.
    • Consolidation of substrates degraded by moisture.
    • Protection of walls in areas with high ambient humidity.
    • Prevention in new construction where there is no impermeable horizontal barrier.

    The Pavi Rep HC System is a comprehensive and technologically advanced solution for the repair and prevention of rising damp in walls and partitions. It combines three key phases that guarantee durable and effective rehabilitation:

    1. Crystallization Waterproofing (Chemical Barrier).
    2. Thermo dehumidification.
    3. Protective Finishes.

    The system is compatible with all types of mineral substrates (brick, stone, concrete, etc.), respects the wall’s breathability, and is designed to offer a definitive solution, from substrate remediation to final protection.

    Frequently asked questions

    What is rising damp?
    It is the ascent of water from the ground through the pores of the wall, without external pressure.

    Through chemical barrier injection, dehumidifying mortars, and breathable finishes

    Yes, the system is suitable for both cases

    Yes, it respects the breathability and hygrometric balance of the substrate.

    It depends on the degree of saturation, but the process begins after injection and mortar application.

    No, except for periodic inspections in critical areas.

    Yes, it complies with UNE-EN 998-1, EN 1062-3, and EN 1542 for mortars and coatings.
