    MasterSeal - Waterproofing products, sealants, foams, membranes and air barriers

    How does MasterSeal work?

    The MasterSeal portfolio of hand and spray-applied waterproofing, joint sealants, fluid applied air-water resistive barriers and deck membranes 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 buildings including car parks, traffic decks, industrial sites, water management facilities for potable water and wastewater, pipes and below ground structures. 

    What makes MasterSeal joint sealants, waterproofing, air-water resistive barriers and deck membranes unique solutions?

    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 waterproofing 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. Our superior technologies are strenuously tested to ensure adherence to local standards and high performance under local environmental conditions. This positions BASF to be the leader in water management solutions worldwide.

    Watertight sealant and foams solutions for all structures

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

    Air-/water-resistant barrier systems for any exterior wall

    Designed for use behind all claddings and at rough window treatments, MasterSeal AWB assemblies create a seamless air/water-resistive barrier and flashing system for all walls on your project. Air barriers, by their nature, must be continuous, with flexible and airtight connections to adjacent systems. 

    Besides the below MasterSeal product range, you can also find adhesive solutions under the brand MasterWeld
