Overview

Flexible and powerful

Bituthene® is available in a number of grades to suit your project needs. Supplied as an easily applied sheet, it can be cold-applied at temperatures as low as 25°F and can be placed on a variety of concrete surfaces. Its robust waterproofing properties, combined with its ease of application, results in a contractor-friendly product that adds value to buildings.

Apply easily, anywhere

Although the chemical properties of Bituthene® make it suitable for a variety of applications, we have added mechanical innovations to further its ease of use and long-term viability.

  • Ripcord® design lets workers easily split release liner for ease of positioning
  • Cold-applied membrane avoids risk of fire during installation due to the fact that flame and/or hot works are not required
  • Self-adhesive overlaps avoid leaky seams and eliminate the need for specialized equipment or training.
  • When used with primer, Bituthene® can easily be applied to damp or green concrete during time-sensitive construction, saving time and money for the project team.

Unparalleled water protection

Buildings change and settle over time, but Bituthene® accommodates those changes.

  • Robust film and specially formulated adhesive provide maximum water protection
  • Flexible yet strong membrane provides crack bridging capabilities and moves with concrete, accommodating minor settling
  • Controlled thickness ensures lack of variation

With so many versatile applications, there’s a Bituthene® solution for nearly every project and design. We provides world-class technical services in order to make those limits even smaller.
