Concrete Spalling is break away of concrete surface which often extends to the top layers of reinforcing steel.
Spalls may be 150 mm or more in diameter and 25mm or more in depth, but we have seen much bigger than this due to being left in the hope it will go away. Spalling of concrete affects a broad variety of structures including framed buildings, multi-story car parks, bridges, jetties, tanks, and bunds. Spalling leaves the concrete surface patchy and pitted but the larger issue is it exposing the structural re-enforced steel and aggregate underneath.
As soon as spalling is spotted, it should be properly repaired otherwise it compromises concrete surface integrity and jeopardizes ultimate capacity of the entire structure. Added to that, spalling could distort aesthetic appearance of the structure.
Causes of Concrete Spalling
- Corrosion of embedded reinforcing steel, because the corrosion products (rust) occupy more volume than the original steel, and the resultant pressure spalls the concrete.
- Fire exposure due to which free water in concrete change to steam and create internal expansive pressure in concrete, consequently, spall off concrete.
- Inadequate depth of cover over reinforcement
- Low quality concrete cover over reinforcing steel.
- Joint spalls are often caused by improperly constructed joints lead to joint spalling
- Bond failure in two-course construction due to the differences in shrinkage between topping and base courses, drying of the bonding grout before the topping concrete is placed etc
How we perform foundation inspections.
One of our knowledgeable inspectors will draw a scaled diagram of the home and take floor elevation measurements after thoroughly inspecting the property inside and out.
We only move to step two if an issue with the foundation is found during the inspection. Our inspector will design a repair plan specific to the property and the issues facing it. They’ll then provide you with a scaled CAD drawing of your home, a full report on the findings, and a suggested repair plan based on those findings will be provided.
We will engage any other professionals that maybe required, such as Geotech and or council and complete to plan.
