Misaligned slab joints are a hazard for forklift operations. As the forklift travels across the step between the slabs there is a jolt that can cause the load on the fork to move. Over time the traffic can cause deterioration of the slab edge.

Open slab joints allow rainwater to infiltrate the subgrade beneath the transport yard pavement. As trucks travel across the slab the soil fines are pumped out from beneath the slab, removing the support of the slab. Over time the voiding beneath the slab increases.

Vibrations from machinery can cause the founding soils to settle and base slabs to subside. In extreme cases the vibrating machinery can cause the surrounding slab to bounce up and down, which is very disconcerting for people working in the vicinity.
