Floor joints are in fact controlled cracks in concrete slabs. They should be designed and positioned to allow the floor to move without restraining that movement. Early life drying shrinkage and long term thermal changes are the main causes of floor joint movement. The sealant used in the floor joint should be rigid enough to provide support and protection to the concrete arrisses, but must also be flexible enough to accommodate any opening of the joint and still remain bonded to at least one face of the concrete slabs.

Joints are often the greatest source of maintenance problems in industrial or warehouse floors. Their edges, or arrisses, are vulnerable to damage and tend to ‘spall' under the impact from hard wheeled traffic.

Most industrial and warehouse floors will have joints with spalled edges and this should be seen as an early indication of more serious long term damage.

Joint edge spalling never gets better with neglect - it always gets worse.

Using the joint reseal detail  in conjunction with a suitable semi-rigid joint sealant, we can reduce or even prevent further edge spalling. However, this relatively simple repair process can only be utilised if the edge damage is detected at an early stage. If more serious damage has already occurred we would need to re-construct the joint ‘arrisses' by using the Joint Arris Repair.
