Slab stop end bars for cavity walls

FLUXX seals the joint cleanly and quickly.

This patented system puts an end to time-consuming and unsightly improvisations when sealing cavity wall joints.

The FLUXX product family consists of two systems.


The FLUXX slab stop end bar, made of specially manufactured flexible steel section, which is clamped in place in the slab joint with a plastic FLUXX locking anchor.
After concreting, the anchor is twisted off and the bar is ready for re-use.


The FLUXX slab stop end floor bar is made of light but durable aluminium rails with two grooves (connection possibilities for clamping pieces with plug screws) and the accompanying FLUXX dowl fixes.

Essential product benefits at a glance:

  • Fast: each joint prepared in less than a minute
  • Only one worker needed
  • Independent of the weather and immediately ready for concreting
  • No tools needed
  • No rework needed
  • Less waste on-site

  • Long service lifetime: Slab stop end bar made of specially manufactured flexible steel section, galvanised and powder coated.
