Comprehensive Waterproofing for Below-Ground Structures

Internal tanking products are designed to create a robust internal waterproof barrier for areas exposed to water ingress. They are specifically formulated to protect substrates such as concrete, brickwork, stone, and masonry, providing a seamless seal that prevents water from penetrating below-ground spaces.

These products play a vital role in ensuring long-term protection for environments prone to high moisture levels, such as basements, swimming pools, vaults, and wet rooms.

 

High-Performance Coatings for a Range of Applications

Internal tanking products are engineered to deliver excellent waterproof protection for various domestic and commercial settings. These include bathrooms, kitchens, and showers, where moisture control is critical, particularly before tiling. Their versatile use extends to industrial spaces like swimming pools and vaults, ensuring complete water resistance for walls, floors, and ceilings.

With their fast-drying nature, these coatings allow for minimal downtime on projects, keeping work on track while delivering a high level of protection.

 

Effective Solutions for Difficult-to-Seal Substrates

Cracks in substrates such as plaster, brickwork, and masonry can allow moisture to seep in, leading to structural damage over time. Specialist internal tanking products are designed to fill these cracks, offering a durable and efficient solution to water ingress. Applied in key areas where water exposure is most prevalent, they serve as a highly effective waterproof barrier.

Simple to apply and formulated for tanking-specific needs, they ensure structures remain water-resistant and durable.
