What to do when you start experiencing concrete rust stains.

window rustConcrete is created by binding together materials such as cement which is the binding agent, crushed stone, gypsum to help with the curing process, rock and sand to help give it strength.

This mixture is then usually poured into a frame which has steel reinforcement through it to give it the structural strength it needs to be used as wall panels, flooring slabs, swimming pools, statues, amongst other things.

It is not uncommon for manufacturers to use recycled concrete as a base which is made from the grindings of old concrete.

This practice enables them to achieve a highly compacted base, weather it’s for your patio, driveway, or garage floor to reduce the risk of cracking and shifting.



So why does Concrete have unsightly rust stains?

Rust stains may have originated from various sources and become visible on your concrete surface even if it has been painted as it will seep through. Concrete rust stains may be caused by the type of aggregate used, as it may contain iron oxide, or from re-bar being placed too close to the surface.

In some cases rust stains on concrete surfaces may be caused by small amounts of contaminants in the aggregate, such as pyrites, or caused by pieces of tying wire left in the form work prior to casting the concrete.

Homeowners can be mistaken to believe that the rust has appeared due to problems with the installation or the concrete mixture; however this is not the case it is often just a cosmetic issue and will not affect the long-term performance of the concrete structure.

It is near impossible to prevent rust build-up on concrete foundations, driveways, porches, patios, and sidewalks. When watering plants and bushes, the rust builds up over time, and leaves behind unsightly orange marks. These marks can turn your office building or beautiful home into an eyesore.
