Construction, isolation and crack-control slab joints
Identify the joint's function before comparing industrial floor profiles. Construction, isolation and crack-control joints address different details within the slab design.
Selection considerations
Use the engineer's joint layout to locate pour boundaries, restrained elements and movement zones. An isolation joint beside a column should not be substituted with a crack-control product simply because both fit the slab depth. Keep the designer's terminology in the schedule.
The BULDX range includes separate isolation, repair and crack-control families. Compare height, geometry and fixing for the stated application. Coordinate the reinforcement and load-transfer detail rather than inferring it from the profile image. Product selection supports the slab design; it does not determine joint spacing or replace the structural layout.
Before you specify or order
- Label the intended joint function
- Use the approved slab layout
- Coordinate reinforcement and load transfer

Common question
Are all slab joints interchangeable?
No. Their function, supporting detail and relationship to the slab design may differ.
