The Gordon Low Firestone pond liner is an impressive 1mm thick, and the premium liner that the company produce. It is extremely tough and durable yet flexible for the best fit possible. Like the other liners in the collection it is both anti-rot and UV so it won't be broken down by weather or debris. It is resistant to microbial elements as well as algae too, and will not split or crack easily, thanks to the advanced manufacturing techniques.
We do recommend using a good quality Gordon Low underlay with every liner. This top quality underlay will form a barrier between the ground and the liner. This stops any sharp objects such as stones from piercing the liner and extend its life.
With a 20 year guarantee, you can be sure that your Firestone liner will look as good as new even years after first use.
