  • Waterproof Coatings

    Coatings Designed to Resist Water & Moisture

    Our Waterproof Coatings range includes specialist protective coatings designed to resist water penetration and protect surfaces exposed to moisture. These coatings form a continuous, durable layer that helps prevent water from reaching the substrate beneath, making them ideal for use on walls, floors, roofs and other moisture-prone areas.

    They’re commonly used where ongoing water exposure or damp conditions are present, providing a practical way to add waterproof protection without major structural changes.

  • Basement Waterproofing

    Protect Basements from Water Ingress & Damp

    Our Basement Waterproofing range includes specialist systems designed to protect below-ground spaces from water ingress, damp and moisture build-up. These products are used to create protective barriers on walls and floors that help manage water penetration and protect the internal structure from long-term damage.

    Whether you’re converting a basement, upgrading a cellar or addressing persistent damp issues, our basement waterproofing systems provide a practical way to improve protection and usability in below-ground environments.

  • Tanking

    Create a Waterproof Barrier in Damp-Prone Areas

    Our Tanking range includes specialist waterproofing systems designed to create a continuous barrier on internal walls and floors, helping prevent water and moisture from entering the internal space. Tanking is commonly used in basements, cellars, utility rooms and other damp-prone areas to manage water ingress and protect internal finishes.

    These systems are applied directly to prepared substrates, forming a sealed surface that helps control moisture and improve the usability of spaces that would otherwise be affected by damp.

  • Waterproofing Tools...

    Everything You Need to Apply Waterproofing Systems

    Our Waterproofing Tools & Accessories range includes the essential items needed to prepare surfaces, apply waterproofing products and achieve a reliable finish. This includes rollers, brushes, mixing tools, reinforcement materials and preparation products designed to work alongside our waterproofing systems.

    By using the right tools and accessories, you can help ensure correct application, consistent coverage and long-term performance from your waterproofing system.
