    ​​​​MasterSeal - Waterproofing and sealants

    How does MasterSeal work?

    The MasterSeal portfolio of hand and spray-applied waterproofing products are formulated to stop water leakages and moisture ingression in a variety of new and existing structures. Our versatile, market leading and innovative technologies are suitable for waterproofing all types of constructions including car parks, traffic decks, industrial sites, water management facilities for potable water and wastewater, pipes and belowground structures.

    What makes MasterSeal a unique solution for customers?

    Local construction expertise coupled with over 100 years of product manufacturing knowledge have led to countless high profile construction and waterproofing successes worldwide. Our global network of experts provides owners, investors, specifiers and applicators with the technical solutions necessary to complete challenging projects.

    In demanding applications such as those on parking decks, bridges and stadiums, where structures are constantly exposed to the elements and subject to abrasive conditions, our high-performance waterproofing traffic membranes deliver outstanding durability and long life cycles.

    The construction industry benefits from our detailed knowledge of the corrosive environment in wastewater facilities, coupled with over a century of concrete repair and protection knowledge. This positions BASF to be the leader in water management solutions worldwide. Our superior technologies are strenuously tested to ensure adherence to local standards and high performance under local environmental conditions.

    Watertight one-stop solutions for all structures

    Our tailored product combinations comprise the fastest and easiest to install technologies available. We create a complete system solution approach, resulting in the most cost-effective and time-efficient waterproofing solution for each individual project.

    Expert consultation and product compatibility between waterproofing and repair systems are essential to a successful project.
