Movement joints are often referred to as "expansion joints" but accommodate both expansion and contraction of building elements. In industrial environments they are often damaged from heavy trafficking by forklift trucks, AGVs, VNA trucks, trolleys and moving machinery - particularly if they have nylon wheels. The edges of the slab can crack, crumble and break-off and /or the joint sealant can fail.
