Liner underlay or foam is an essential extra for achieving the best possible finish for your newly lined pool. Suitable for site lined and bag lined pools, liner underlay or foam offers slight cushioning and protection to the rear of the lining and contributes a smoothing effect to the pool shell.
Our reinforced underlay felt is a heavier duty (375g per m2) and includes a woven scrim which makes this felt more rigid and easier to position on the pool shell planes – it is also more durable and is commonly used in site lining installations and is available in full rolls of 50m x 2m.
