Armored Membrane in Jerez de la Frontera: Pool Installation and Refurbishment
If you are looking for armored membrane in Jerez de la Frontera to waterproof your new pool or refurbish an old one, at ARG Piscinas we are official Renolit Alkorplan installers with over 15 years of experience in Cádiz and across Andalusia. The Jerez climate —long dry summers, intense sun, proximity to the Bay of Cádiz and very hard water— demands a membrane that resists wear without cracking or fading. Reinforced PVC armored membrane is today the most reliable solution for residential and community pools across the Cádiz countryside and coast.
What is armored membrane and why choose it in Jerez
Armored membrane (also called reinforced PVC) is a 1.5 to 2 mm thick waterproofing membrane made of two PVC layers with an intermediate polyester mesh that gives it mechanical strength and dimensional stability. Unlike a prefabricated liner, it is hot-air welded on site, adapting to any shape, staircase, beach entry or spa. The result is a fully watertight, continuous shell with no vulnerable joints.
- Real durability: between 15 and 25 years with proper maintenance.
- Adaptable: suitable for concrete, gunite or panel pools.
- Repairable: a cut or puncture is welded without draining the whole pool.
- Aesthetics: wide range of colours and anti-slip textures.
At ARG Piscinas we work exclusively with certified materials and professional welding. See the full scope of our installation and refurbishment services and real cases in our projects section.
The Jerez climate: salt air, intense sun and hard water
Jerez de la Frontera lies just a few kilometres from the sea, in an area where salt air carried by the westerly wind affects outdoor installations. On the nearby coast —El Puerto de Santa María, Sanlúcar de Barrameda, Chipiona or Rota— this effect is even stronger. Salt attacks metals and degrades conventional liners, whereas PVC armored membrane is chemically inert and does not corrode.
Add to this powerful sun for much of the year, exposing the pool to strong ultraviolet radiation, and the very hard water typical of the countryside, rich in lime. Renolit Alkorplan membranes feature anti-UV and antimicrobial protection, keeping their colour and preventing stains and biofilm even under Jerez's thermal regime, with days above 35 °C in midsummer.
Why armored membrane is ideal for the Cádiz climate
The great enemy of pools in Jerez and its surroundings is not only the heat, but the thermal swings between day and night and ground movement. Reinforced PVC has enough elasticity to absorb small stresses without cracking, something that tiling or chlorinated rubber paint cannot tolerate. Under the membrane we always lay a geotextile that protects it from roughness and, in old pools, from micro-cracks in the substrate.
| Jerez climate factor | Armored membrane response |
|---|---|
| Coastal salt air | Inert PVC, does not corrode or degrade |
| Intense UV radiation | Anti-UV layer that preserves colour |
| Hard water and lime | Smooth surface, easy to clean, fewer deposits |
| Day/night thermal swings | Elasticity that prevents cracks |
That is why we recommend armored membrane both for villa pools in areas such as Montealto, La Granja or the outskirts of Jerez, and for residents' communities downtown and developments on the nearby coast.
Armored membrane installation in new pools
In new builds, armored membrane has become the preferred finish for its fast commissioning and its guarantee of watertightness from day one. We prepare the substrate, install perimeter profiles, lay the geotextile and weld the membrane around lights, skimmers, return nozzles and stairs. Discover the details of our armored membrane installation in new pools service, designed for builders and homeowners in Jerez and the province.
Refurbishment of old pools and liner replacement
Is your pool losing water, with loose tiling or a faded, stiff liner? Armored membrane is the definitive solution to refurbish old shells without costly demolition. It is installed directly over existing tiling, paint or concrete, restoring watertightness and giving a like-new look. Check our services for installation in old pools and liner replacement and accessory refurbishment if you also need to renew skimmers, lights or stairs.
- Detection and sealing of frequent leaks from evaporation and salt.
- Replacing an old liner with a more durable armored membrane.
- Aesthetic renewal with current colours and anti-slip textures.
Frequently asked questions
How much does it cost to install armored membrane in a pool in Jerez?
The price depends on the pool's square metres, its shape and the condition of the substrate. The most reliable way is a technical visit to measure and assess. At ARG Piscinas we offer a free, no-obligation quote in Jerez de la Frontera and across the province of Cádiz.
How long does armored membrane last with the sun and salt of Cádiz?
With proper water and chemical maintenance, a Renolit Alkorplan membrane lasts between 15 and 25 years, even in coastal areas with salt air, thanks to its anti-UV treatment and inert PVC composition.
Can armored membrane be laid over existing tiling?
Yes. One of the great advantages is that it is installed over tiling, paint or concrete without demolition, with its protective geotextile underneath. It is the fastest, cleanest way to refurbish old pools in Jerez.
Do you work only in Jerez or also in the villages and on the coast?
We cover Jerez de la Frontera and its whole area: El Puerto de Santa María, Sanlúcar, Chipiona, Rota, Arcos de la Frontera and the rest of the province, as well as working across Andalusia and Spain.
