What we do
SPALLING REPAIR
Spalling (Concrete Cancer) is most often identified by signs such as flaking (concrete spalling), rust stains that leach from the concrete, bulging of the concrete or in some cases even falling off the building. The real problem lies within the concrete itself and is not a result of weathering.
As a general rule, Spalling is caused by the steel reinforcing within a concrete slab rusting. As steel rusts, it can expand up to 7 times its original size causing the surrounding concrete to be displaced and flakey.
The process can start in many ways, but generally, it is due to one of the following:
- Poorly treated reinforcing steel being used in the original pour of the slab
- The reinforcing steel being too close to the surface allows water to seep through the concrete and react with the steel
- Incompatible metals being used in close proximity to each other, thus causing a reaction
- Fractures in the concrete allow water to penetrate the concrete and react with the steel
Spalled concrete is an eyesore and a hazard. Over time, with increased exposure to the elements, falling concrete debris causes likely injury and damage to property. Spalling concrete should be repaired immediately, as deferring the treatment will inevitably lead to increased problems into the future.
Furthermore, any attempts to fix the problem for the short term (such as parging over the problem) will only exacerbate the issue. Despite, potentially looking better, the rusting process will continue below the surface causing the steel to again displace the concrete and in some cases rust so badly that the steel eventually needs replacement. Treatment and repair of the concrete is the best solution.
Dafco, have staff who are trained in the identification of underlying issues. Once found we will begin the process of concrete spalling repair by removing all loose concrete, grinding back the reinforcing steel to remove all rust, treating the steel with anti-corrosives and then patching the repair with a top-quality concrete to match the original surface.
