    What is on site lining RENOLIT ALKORPLAN for swimming pools?

    The on site lining RENOLIT ALKORPLAN is a decorative and watertight reinforced membrane or liner for swimming pools.

    It is made up of two flexible sheets of polyvinyl chloride (PVC-P), providing the pool with total, long-lasting and watertightness.
    These two sheets are laminated with a core of a polyester mesh, that provides great strength and durability, without losing the elasticity and flexibility needed to adapt to any shape or corner of the pool.

    This lining system is suitable both for new build swimming pools and for refurbishments.


    It can be installed in half the time of other lining systems on any type of surface and onto any pre-existing material, (except surfaces treated with bituminous sheets), adapting to the shape of any pool shell.

    Nowadays, it is the most advantageous system in the market and the one that presents the fewest problems. Its attractive appearance, reasonable price, fast and easy installation and absolute water-tightness, guaranteed for 10 years, have made it the most widely-used pool waterproofing system in the world.

    It's the only on site lining on the market with an antiblocking lacquer on the bottom, which improves material handling during installation.

    Our reinforced membranes contains in the top sheet:
    • pigments of the highest quality to ensure excellent resistance to ultraviolet rays.
    • a non-volatile plasticiser to ensure flexibility and ensure prolonged useful life.
    • an excellent stabiliser that makes the membrane dimensionally stable during sharp changes of temperature
    • a protective lacquer that protects the surface against scratches; ultraviolet rays, and acts as a stain repellant

    The bottom sheet contains a fungicide to prevent the proliferation of bacteria that can stain the membrane.

    All RENOLIT ALKORPLAN on site liners are 100% watertight with a written guarantee

    The RENOLIT ALKORPLAN liner is varnished

    The top surface of the RENOLIT ALKORPLAN 2000/3000 pool liners are coated with an exclusive protective varnish, which has the main function of extending the liner’s useful life.

    Our varnish has a high concentration of U.V.-absorbing materials, which provide the best protection against sunlight, the effects of time or adverse weather conditions.

    The varnish forms a barrier between the liner and the water, preventing the migration of the plastifying agents and premature ageing of the liner.

    This varnish ensures the liner maintains its resistance and flexibility over a long period of time.

    It also acts as a protective shield against attacks by micro-organisms.

    Furthermore, the varnish repels stains caused by suntan oils, lime scale deposits, organic matter and micro-organisms.

    Benefits of the lacquer

    • Prevents the development of bacteria and fungi, making the pool more hygienic.
    • Protects the liner from UV radiation and prevents premature ageing.
    • Repels dirt and stains, and facilitates the cleaning of the liner.
    • Acts as a shield against abrasion and due to continual use.

    If you want an attractive pool that will give you no problems, RENOLIT ALKORPLAN reinforced liner is the perfect product to achieve this!

    It can be installed on any surface.

    Clean installation, with no noise and in half the time it takes to install other liners.
