THE CONCEPT

The BFL-MASTIX system is conceived to assure long term watertightness of joints, in particular adapting to the deformations in concrete structures.

CONSTITUTING ELEMENTS OF BFL-MASTIX BANDS

In order to adapt to structure movements, the core of the BFL-MASTIX bands is constituted of a watertight plasto-elastic, non-rotting and root-proof material. To assure watertightness, the core adheres by glueing to hard concrete and to fresh concrete by incrusted fine crushed gravel.

The gravel plays the role of an adherence bridge between the core and the fresh concrete.

It concerns the part of the band that is not gravel coated and serves for the gluing to a support (hard concrete, metal, asbestos-cement, sealing foils, etc.).

That’s the part of the band capable to freely deform in order to absorb movements without rupture of the interface core/gravel or glued surface/support.
