We’re going to take a look at aluminum pools, and how RenoSys solves a common problem they develop.

Aluminum pools are particularly common indoors and in high schools. They face a specific and unique issue in the form of galvanic corrosion. While galvanic (or electrolytic) corrosion sounds like a complicated scientific process, essentially it’s like an accidental battery that leads to corrosion on the pool shell. It occurs when metal meets with a charge from an outside source. This leads to a detrimental corrosive reaction.

What does this mean for your aluminum pool?

The short answer is that the longevity and integrity of your pool are in jeopardy.

When you have an aluminum or mild steel pool, the electrical charge present in the water acts as that charge against the metal – and you can end up with pool-damaging degradation. Aluminum pools protect against this by using what are termed sacrificial anodes. They are metal blocks that attract the corrosion away from the pool shell. The anodes are reasonably effective but they must be replaced when they start to fail. Because stainless steel pools have become the preferred modern pool structure, the majority of aluminums pools out there are more than 25 years old. After time, the importance of replacing the anodes is either overlooked or misunderstood, and your pool may need a serious overhaul.

Damage to aluminum pools can be extreme.

However, one of the great features of the RenoSys PVC pool membrane is that it can be used to completely renovate an aluminum or other mild steel pool to nearly eliminate the galvanic-corrosion effect without the need for major structural work.

How can RenoSys remove an inherent factor of deterioration in aluminum pools?

It comes down to good insulation, and PVC is a very effective insulator. A RenoSys pool membrane liner is composed of 60 mil PVC that serves as a high-performing barrier between any electrical currents in the pool water and the aluminum of the pool itself.

Although not all aluminum pool renovations are due to corrosion (some are simply pools that are aging and need repair), our familiarity with this common corrosive issue and ability to transform your aluminum pool is unparalleled.

We frequently encounter aluminum swimming pools in schools with badly deteriorated pool gutters and main drains. This results in large amounts of expensive water loss. Because it is naturally more resistant to corrosion, we use stainless steel when replacing critical components like these.

Before you decommission or demolish a pool that seems like it can’t be saved, consider renovating instead. You’ll be amazed by what’s possible.
