If you've noticed rust in your swimming pool, talk to us about our rust repair service
Concrete swimming pools are built with a combination of reinforcement bars and concrete, the steel reinforcement bars are tied together with steel cable ties.
There are also other parts within the pool that are made of metal, this could be the screws for the pool lights, stainless steel ladders, the bolts that hold the pool ladder together, screws that connect the pool fittings together like suction covers & the main-drain of the pool.
As you can see, there are lots of bits and pieces that might have steel under the swimming pool water.
Problem is, sometimes over the years some pool owners DIY or other tradies may have used steel that was not stainless, or not the right type of grade.
Though most times, rust problems in swimming pool are due the reinforcement bars or the cable ties are too close to the pool surface.
Rust spots tend to be bigger beneath the surface. In this image, the pool render was removed exposing the rusted cable ties that were causing a rust stain, the original rust stain was around 20mm showing on the pool surface. The concrete was cut open, the steel cables ties removed, all rusted concrete was also removed before filling in with an epoxy filler and re-rendered.
When reinforcement bars rust in a swimming pool, the rust tends to spread along the length of the bar, so it is important to repair the rust spots as soon as they are noticed to avoid issue spreading onto other bars and coming through more areas of the surface.
