BITUTHENE® 3000 and BITUTHENE® Low Temperature Membranes are self-adhesive, rubberized asphalt/polyethylene waterproofing membranes for elevated plaza and parking decks and below grade basements, tunnels, and other subterranean applications.
- Provides a barrier to water, moisture and gas by physically isolating the structure from the surrounding substrate
- Cross laminated ﬁlm - Provides dimensional stability, high tear strength, puncture and impact resistance
- Cold applied - No ﬂame hazard; self-adhesive overlaps ensure continuity
BITUTHENE® 4000 system combines a robust, flexible, pre-formed membrane made of a high performance, cross laminated, HDPE carrier film with a tacky, self-adhesive rubberized asphalt compound and BITUTHENE® 4000 surface conditioner.
- Provides a barrier to water, moisture and gas — physically isolating the structure from the surrounding substrate
- Excellent adhesion — Special adhesive compound engineered for use with BITUTHENE® 4000 surface conditioner
- Cross-laminated, high density polyethylene carrier film provides high tear strength, puncture and impact resistance
BITUTHENE® Deck Prep is a low viscosity, two component, asphalt-modified urethane coating. It is used to level and repair rough concrete decks to which BITUTHENE® waterproofing membranes will be applied.

BITUTHENE® Adhesive Primer B2 LVC is a low VOC primer in solvent specially formulated to provide good initial adhesion of GCP self-adhered membranes.
- Low VOC primer
- Promotes the adhesion of GCP self-adhered membranes to green concrete and damp surfaces.
- Compliant with all state and local VOC requirements
- Prime green concrete (less than seven day cure for normal structural concrete)
- Prime damp concrete, masonry, gypsum sheathing or wood surfaces on which GCP self-adhered membranes will be applied.
- For vertical and horizontal applications at 25 ºF (-4 ºC) or above
BITUTHENE® Mastic is a rubberized, asphalt-based mastic. It has excellent adhesion to structural concrete, masonry and wood. The VOC (Volatile Organic Compound) content is 200 g/L.
- Excellent adhesion
- Seals terminations, edges of patches and overlaps in detail areas
- Designed to seal terminations, edges of patches and overlaps in detail areas
BITUTHENE® Primer WP-3000 is a water-based latex primer which is specifically formulated to bind dust and concrete efflorescence, thereby providing a suitable surface for BITUTHENE® membranes.
- Specifically formulated to bind dust and concrete efflorescence
- Excellent permanent adhesion
- Used to prime all structural concrete, masonry or wood surfaces on which BITUTHENE® membranes will be applied.
- Used for vertical and horizontal applications at 40 ºF (5 ºC) or above.
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
