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 specialised 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
