Foam underlay is great for protecting your liner from your swimming pool wall.
The foam is 8mm thick and is applied to your pool wall with adhesives. This allows it to prevent a barrier and cushions your liner when it is stretching when filling your pool up. It is available in two different heights depending on the pool you have.
Foam underlay is not recommended in high waterable areas.
This is a chart to get a estimate on how much foam you would need for your swimming pool. Allow 10% extra for wastage.
