Reinforced Membrane in El Puerto de Santa María: Pool Installation and Renovation in the Bay of Cádiz
If you are looking for reinforced membrane in El Puerto de Santa María, you have come to the right place. At ARG Piscinas we are official installers of Renolit Alkorplan reinforced membrane with more than 15 years of experience waterproofing pools across the Bay of Cádiz. The Atlantic climate of El Puerto (high humidity, salt-laden sea breeze and intense sun from May to September) puts pools under a strain that few finishes can resist. Reinforced PVC membrane, hot-welded and reinforced with a polyester mesh, is today the most reliable solution for your pool to last in El Puerto without leaks or cracks.
Why reinforced membrane is ideal in El Puerto de Santa María
El Puerto de Santa María sits right by the sea, at the mouth of the Guadalete river, which means airborne salt all year round. Sodium chloride attacks cement, rusts metal anchors and degrades gunite and conventional liners surprisingly fast. Reinforced PVC membrane is a non-porous, chemically stable material designed for aggressive environments: it does not corrode, does not absorb moisture and keeps its elasticity despite the salty breeze.
Add to this the solar radiation of the Cádiz coast. Renolit Alkorplan membranes include anti-UV treatment and an acrylic lacquer layer that prevents premature fading and slows algae growth. In an area where the swimming season runs from April to October, that durability is the difference between repainting every few years or forgetting about it for over a decade.
- Salt resistance: a waterproof surface that isolates the shell from salty water and ambient humidity.
- Hot welding: heat-fused joints that create a continuous, watertight membrane with no leaking seams.
- Adapts to any shape: it fits concrete pools, steps, beach entries and the free-form designs common in the area's villas.
- Real 1.5 mm thickness: with polyester mesh that adds mechanical strength against movement of the sandy ground.
Reinforced membrane installation in new pools
If you are building your pool in El Puerto, Valdelagrana, Vistahermosa, Fuentebravía or any coastal development, the reinforced membrane should be part of the project from the start. We first apply an anti-puncture geotextile that protects the membrane from the substrate and spreads tension, then we fit the perimeter anchoring profiles and finally we unfold and weld the membrane point by point. The result is a fully watertight shell ready for decades of use. See the details in our new pool reinforced membrane installation service.
Renovation of old pools in the Bay of Cádiz
Many pools in El Puerto built 20 or 30 years ago start to lose water, show stains, loose tiles or paint cracked by the salt. The good news is that there is no need to demolish: reinforced membrane is installed directly over the existing shell, whether concrete, tile or polyester. We repair cracks, level the surface, lay the geotextile and reline the entire area. Within a few days your pool is watertight and looks brand new again. Discover how we work in renovation of old pools and in liner replacement and accessory rehabilitation.

Frequently asked questions
How long does reinforced membrane last with El Puerto's salt?
A properly installed and maintained Renolit Alkorplan reinforced membrane easily exceeds 12-15 years even in a marine environment. Salt does not penetrate the PVC, so its lifespan far surpasses that of a conventional liner or paint.
Can I put reinforced membrane over my old tiled pool?
Yes. Reinforced membrane is installed directly over tile, concrete or polyester without demolition. We only repair and level the substrate before relining, which saves a lot of time and money.
How long does the installation take?
A standard residential pool is usually ready in 4 to 7 working days, depending on its condition and size. We give you a fixed timeframe in the quote after the technical visit.
Do you only work in El Puerto de Santa María?
We serve the entire Bay of Cádiz (Puerto Real, Cádiz, San Fernando, Chiclana, Rota, Sanlúcar) and the rest of Andalusia and Spain.
