Spalled Edge

Summary

Spalled Edge - is a term used to describe the damaged condition of joint arris in a concrete floor slab where fragments of the arris are broken off and the arris is no longer at 90°.

Technical Information

Floor Joint Spalled Edge

A spalled edge can be caused by a joint being too wide or the two oposing slabs being different in vertical elevation. As materials handling equipment (MHE) traffics the joint, their wheels will hit against the arrises of the slabs, in turn, breaks the concrete eventually to the extent where it can ‘round’ the arris edge. Once the edge of the concrete slab has began to spall it is a self-perpetuating problem that will only get worse if prompt action is not taken to repair the joint and avoid further damage.
Spalled edges at floor joints can also be an indication of poor or no load transfer capacity at the joint.

They are repaired using a cut and fill method so that, once again the arris is 90° and the joint is narrower, significantly reducing the potential of future damage from MHE movements. Using CoGri Rapid Mender, the new arrises can cure in 30 minutes.
