Sika® FloorJoint EX

Carbon fibre prefabricated floor joint panel

Sika® FloorJoint EX is a carbon fibre reinforced polymer (CFRP) composite, prefabricated, floor joint with high mechanical resistance for normal up to medium wear loading conditions. Its sinusoidal surface tooth profile allows for an improved load distribution and results in minimum vibrations under direct car and forklift traffic. The eccentrically arranged teeth rest completely on the opposite side of the joint even when the joint is widened. The joint is easy and quickly to install and reduces vibrations from all types of wheel loadings. Sika® FloorJoint EX is the main part of the Sika® FloorJoint PB-30 EX System.

  • Grindable profile for level integration into the floor surface
  • Reduced vibrations under direct car and fork lift traffic
  • Thermal expansion coefficient similar to resin based floors
  • Easy to install / Easy to repair
  • Short down time - Trafficable after 24 hrs
  • Waterproof system design possible
  • High chemical resistance
  • Non corroding
  • High mechanical resistance

  1. Width of the gap in the concrete below Sika® floor Joint panel during installation.
  2. Positive joint movement is the amount the gap can open, compared to its original width during installation of the Sika® floor Joint panel. Don't exceed the maximum positive joint movement capacity, otherwise the teeth of the Sika® floor Joint panel will become unsupported and may be damaged.
  3. Negative joint movement is the amount the gap can close, compared to its original width during installation of the Sika® floor Joint panel.

Note: The sealant may break at a positive joint movement of approx. 15–20 mm, however this does not affect the technical performance of Sika® FloorJoint EX. The purpose of the joint sealant is the reduction of dirt pick-up in the joint, not to provide water tightness. Install Sikadur® Combiflex® SG System below Sika® FloorJoint EX if a waterproof joint design is required.
