Pool underlay 4.80 x 4.80 m
The 4.80 x 4.80 m pool underlay is a square sheet of non-woven geotextile that measures 480 x 480 cm. You place it under the pool base during installation. Thus, the liner stays protected from sharp objects in the ground.

The density is higher than that of standard thin versions. That makes the underlay a good choice when the ground is not completely smooth.
Geotextile underlay 4.80 x 4.80 m – protection under the pool base
Manufacturers make the underlay from non-woven geotextile of 100% polypropylene. Also, the colour is grey or white, depending on availability. Moreover, the material resists petrol, perchlorate, oils and other chemicals of a similar nature. Besides, it protects against the growth of fungi and microorganisms, so it is harmless to health.
The density is 200 g/m², so it provides good protection for the liner of prefabricated pools. For inflatable pools, the underlay protects the vinyl much more effectively than standard thinner underlays do. Also, we cut the underlay into a square measuring 480 x 480 cm.
A good underlay extends the life of the pool, because pebbles, roots and bumps cannot press directly on the liner. That is why it is worth laying it at the very first installation.

Geotextile pool underlay: advantages
The underlay is easy to lay, so it needs no special tools. You simply spread it over the prepared ground before unfolding the pool. Then you install the pool on top of it as usual.
Thus, you get an additional layer between the ground and the liner. It also cushions the pressure of bumps and reduces the risk of punctures. The result is a longer pool life and fewer worries during the season.
We chose the 480 x 480 cm dimensions specifically for pools of this class. If your pool is smaller, the underlay will cover it completely and leave a margin around the edges.
