Most warehouse and industrial floors become subject to joints with spalling edges. This should be seen as an early indication of serious potential for long term damage. The floor joint edges are vulnerable to damage and tend to spall under the impact from hard wheeled traffic. Also these floors are subject to random cracking.
Floor joints are controlled cracks in concrete slabs and are designed and positioned to allow movement in concrete floors. Without restraining that movement it could lead to random cracking. Early life drying shrinkage and long term thermal changes are a few of the main causes of concrete floor joint movement. Joint sealant should be rigid enough to provide support and protection to the concrete. However, it must also accommodate the anticipated movement in the floor while remaining bonded to at least one face of the joint. Crack repairs to warehouse floors help to prevent further degradation of the floor and create a smooth surface. This provides increased mobility to heavy forklifts or pallet jacks and reduces trip hazards for employees and general public use.
