ABSTRACT
Joints play a significant role in the performance of concrete industrial floors. To achieve desirable load transfer capability across the joint and meet the flatness and levelness requirements, a combination of good design and construction practices is required. Although there might be local guidelines available in some countries, the leading global guideline for industrial slab design and construction is Technical Report 34 - 4th Edition (TR34.4)- Concrete Industrial Ground Floors. TR 34.4 provides detailed information on joint types, joint layout, load transfer calculation, armouring of joints and joint sealing. To choose the most appropriate joint type from the wide array of prefabricated industrial floor joints available in the market, it is crucial that designers and contractors fully understand the advantages and disadvantages of each type. This paper highlights the design and construction requirements for industrial floor joints, as delineated in TR34.4. It also provides information on various prefabricated joints in the market along with guidelines on the maintenance of existing and remediation of damaged floor joints.
