Sheet membrane waterproofing. CETBIT 300 is a self-adhering sheet waterproofing membrane consisting of 1.4 mm of rubberized bitumen integrally bonded to a 0.1 mm cross-laminated HDPE protective film. These two components combine to offer an extremely effective waterproofing barrier with a factory controlled thickness to ensure uniform application.
The cross-laminated HDPE film provides dimensional stability to the membrane plus ensures uniform reaction to elongation stresses in both longitudinal and transverse directions.
CETBIT 300 is supplied in 1.0 m wide by 20.0 m long rolls. The rubberized bitumen is covered with a siliconized release paper which is removed immediately prior to installation. The membrane is self-adhering and cold-applied. No special equipment or adhesives are necessary to form laps.
CETBIT 300 requires accessory products for surface conditioning and detailing, such as penetrations, corners, and terminations. Use only accessory products supplied by the manufacturer.
Applications:
CETBIT 300 is ideal for waterproofing structural concrete, masonry and wood surfaces where the inservice temperatures will not exceed 40°C. CETBIT 300 can be applied to foundation walls, tunnels, and earth sheltered structures. It also is used in split-slab construction, both above and below ground, such as plaza areas, balconies and parking decks. Interior uses include mechanical rooms, kitchens, bathrooms, and laboratories.
CETBIT 300 should not be used where it will be permanently exposed to sunlight. Do not use CETBIT 300 as a traffic wearing surface.
Packaging:
Each roll of CETBIT 300 is individually packaged in a strong corrugated cardboard box. Pallet contains 20 rolls. Do not double stack pallets.
