Armored Membrane Pools in Granada: Built to Handle Thermal Shock
If you are looking for an armored membrane pool in Granada, you first need to understand the challenge posed by the province's climate. Between the Vega de Granada, with its cold winters and dry, intensely hot summers, and the Costa Tropical of Motril, Almuñécar and Salobreña, with its mild but salt-laden microclimate, a Granada pool faces very different demands depending on where it is. At ARG Piscinas, official Renolit Alkorplan installers with over 15 years of experience, we use armored membrane (1.5 mm reinforced PVC) precisely because it is the lining that best absorbs these stresses without cracking or leaking.
Why armored membrane is ideal for Granada's climate
The biggest enemy of pools in the interior of the province is thermal shock. In the Vega de Granada, in towns such as Santa Fe, Las Gabias, Armilla, Maracena or Atarfe, it is common to go from overnight frost in winter to over 38 degrees in the sun in mid-July. That continuous cycle of expansion and contraction is what cracks tile mosaic, fissures mortars and splits exposed concrete. Armored membrane solves the problem because it is a flexible, continuous lining: it moves with the pool shell instead of resisting it.
- Elasticity: reinforced PVC tolerates the shell's expansion without flaking, which is key in areas with strong temperature swings.
- Total waterproofing: being a continuous welded membrane, it eliminates the joints where water seeps through when there are micro-cracks.
- UV resistance: the Andalusian sun is relentless; the acrylic lacquer layer protects the colour against radiation.
- Anti-stain and anti-algae treatment: essential with the hard, calcareous water common across much of the province.
Vega de Granada: continental climate and hard water
In the Vega and the metropolitan belt, the challenge is not only temperature but also water hardness. Calcareous water favours scale build-up and accelerates the deterioration of rigid linings. Armored membrane, with its smooth surface and factory treatment, is far easier to clean and better resists the chemical attack of demanding water. For built pools that already show cracks or water loss, our armored membrane installation for old pools lets you recover the shell without demolition, welding the membrane over the existing structure after preparing it with geotextile and anchoring profiles.
Costa Tropical: Motril, Almuñécar and Salobreña against salt air
On the Granada coast the climate is much milder in temperature, but another factor comes into play: the saline environment. The proximity of the sea in Motril, Almuñécar, Salobreña or La Herradura introduces salt into the air that corrodes metal fittings and degrades porous finishes. Renolit Alkorplan armored membrane is unaffected by salt and is perfectly compatible with salt chlorination systems, very common on the coast for their convenience and gentleness on the skin. It is an ideal combination for second homes and pools used intensively in summer.
Pool installation and renovation in Granada
We work on both new builds and renovations throughout the province. For newly built pools, our armored membrane installation for new pools guarantees perfect waterproofing from day one. When the shell already exists but is failing, armored membrane is the most cost-effective alternative to a full rebuild.
| Need | Recommended solution |
|---|---|
| New concrete pool | Armored membrane over geotextile and profiles |
| Old shell with cracks or leaks | Renovation without demolition |
| Old or faded liner | Liner replacement and accessories |
If your current lining is a worn liner, our liner replacement and accessory renovation service completely renews the look and watertightness of the pool. You can see real examples in our projects or browse the full catalogue of services.
How we install armored membrane step by step
- Shell preparation: repairing cracks and levelling the surface.
- Geotextile: a layer that protects the membrane and absorbs minor irregularities.
- Profiles: perimeter anchoring that secures the membrane at edges and skimmers.
- Hot-air welding: joining the sheets with hot air to achieve a 100% continuous, watertight membrane.
- Sealing and finishing: joint treatment with liquid PVC and fitting of accessories.
The entire process is carried out by our own specialised staff, with no subcontractors, allowing us to guarantee the result on every pool in Granada and its province.
Frequently asked questions
Does armored membrane withstand the frosts of the Vega de Granada?
Yes. Being a flexible lining, armored membrane absorbs the expansion and contraction of the shell caused by interior thermal shock, avoiding the cracks suffered by tile mosaic and rigid mortars.
Is it compatible with the salt chlorination of the Costa Tropical?
Absolutely. Renolit Alkorplan resists salt air and salt water without degrading, making it the perfect choice for pools in Motril, Almuñécar or Salobreña.
Can I renovate my old pool without demolishing it?
In most cases, yes. We prepare the existing shell and weld the armored membrane over it, restoring watertightness without major works or demolition.
How long does an armored membrane pool last?
With proper maintenance, a 1.5 mm Renolit Alkorplan armored membrane offers a service life of 15 to 20 years, far longer than a conventional liner.
