BEKINA® BeSealed Bentobar+ 20x25 mm Black (30 m)
Self-expanding sealing bars
AREA OF APPLICATION:
Hydrophilic sealing bar made of sodium bentonite and butyl rubber for preventive sealing of construction joints and as a system component for bentonite mats. Mechanical fixation can be performed with BeSealed fixing glue for water swellable sealing profiles or by nailing.
PROPERTIES:
- Developed for preventive sealing of construction joints in concrete and reinforced concrete construction. Alternatively BENTOBAR+ can be applied as a system component for bentonite mats. It seals against non-pressing and pressing ground water up to 6 bar.
- To ensure a continuous section of the sealing bar, an overlap of 5 to 10 cm is applied and the bar ends are firmly pressed together. A minimum concrete coverage of 7-8 cm on each side is required.
- BENTOBAR+ can be applied both vertically and horizontally, but under no circumstances should it be used in expansion joints.
- For salt water environment, in polluted water conditions and in contact with manure and slurry, we recommend BENTOBAR+ SW (See separate TDS).
