A luxurious and long-lasting quality liner, both for new and for reconstruction of built pools. The PVC film has a three-layer structure reinforced with a fiber mesh. It is stored in rolls with different widths – 1.65 or 2.00 m and length – 25 m. It can be of different thickness – 1.50 and 2 mm. In places in and around the pool where there is a risk of slipping (monolithic steps and front board of the overflow chute) it is correct to cover it with an embossed PVC foil, which is glued on top of the already installed smooth foil. This type of lining has other advantages: it has a high water permeability, moreover, it allows to cover pools with various complex shapes. The strength of the PVC film can only be broken mechanically by a sharp object or an object with sharp edges left under it. In case of unevenness on the bottom of the pool and to protect the film, we recommend laying geotextile under it.
