Surface Sealing

Bituminous external sealing for underground building structures

Structural elements with ground contact such as basements, underground car parks, retaining walls and terraces must be protected from the penetration of soil moisture and seepage water. Polymer modified high-build bituminous coatings are suitable for sealing these surfaces. Special bituminous acrylate dispersions can also be used.

Products Used

  • Dispersion for Walls and Floors

    WEBAC® 5611

    • Classic Line

    WEBAC 5611 is a reactive bitumen-acrylate dispersion that adheres well to a wide variety of substrates and has crack-bridging properties. The hydrophobic effect of the bitumen component creates a waterproof seal with reliable protection against leaching by salts harmful to structures. This makes WEBAC 5611 suitable for surface waterproofing against hydrostatic pressure in building construction, civil engineering, and historic preservation.
