What it involves

A reinforced membrane is a PVC sheet strengthened with an internal mesh that is installed over the existing shell and welded in the pool itself, sheet by sheet, to form a continuous, watertight lining. A classic liner, by contrast, is made up like a bag to fit the pool and hung from a rail around the edge; it is the usual choice for panel and above-ground pools.

It is the most direct way to renovate a pool without chipping off or demolishing anything: it covers old mosaic with loose tiles, ends the cycle of repainting every season and leaves a waterproof shell with a uniform finish. We measure precisely, prepare the substrate, lay geotextile underlay where needed, fix the rails, weld with hot air and finish skimmers, return jets, lights and steps with their flanges and gaskets.

We work for villas, holiday homes that need the pool ready without a long job, owners’ communities and holiday accommodation along the coast. If the pool is losing water, we first find out where it is going; if you want to change the steps or edges, we plan that as a renovation before fitting the membrane.

Liners and PVC membrane: jobs we do

These are the jobs we are asked for most around the province. If yours looks like one of them, call us and we will tell you how we would handle it.

Reinforced PVC liner over old pool tiles

This is the most common case: a concrete pool with mosaic tiles coming away in chunks, black grout and ingrained limescale. Instead of chipping off the whole shell, we remove only the loose or sharp tiles, fill hollows and level the surface, lay a geotextile underlay that protects the membrane and smooths out bumps, and weld the reinforced membrane on top. The result is a continuous lining, with no joints for algae or limescale to cling to, a much shorter job, less rubble and no work on the structure of the pool.

Replacing a torn or faded pool liner

Over the years, sun and badly adjusted chlorine fade the liner and make it brittle, and cracks appear in the corners or along the waterline. When it is already losing water or looks stained and dull, we replace it: we drain the pool, remove the old liner, check the substrate and underlay, change the skimmer and return-jet gaskets and fit the new one, either a made-to-measure liner hung from the rail or a reinforced membrane welded on site. Before removing the old one, we find the cause of the wear so it does not happen again.

Made-to-measure liners for panel and concrete pools

A well-fitted liner neither wrinkles nor sits under too much tension. We take measurements in the pool, including the depth at every point, the slopes, the steps and the position of skimmers, return jets and lights, and order the liner made to the exact size. During installation we hang it from the rail, settle it with a vacuum while the pool fills to draw out any trapped air, and cut the openings for the built-in fittings with their flanges. It suits panel pools and rectangular concrete pools.

Reinforced PVC liner over a painted pool

If every spring the shell has to be sanded and repainted because the paint is peeling or blistering, a reinforced membrane ends that cycle. We remove loose paint, repair chips and cracks in the concrete, lay geotextile and weld the membrane over the shell. You get a watertight pool with a uniform finish that does not crack in the sun and only needs routine cleaning. It is a very practical solution for holiday homes where nobody wants to repeat the same job every season.

Reinforced pool liner colours and textures

Reinforced membranes are no longer just plain blue. There are white and sand shades that give a very pale turquoise, greys and anthracites that create a lake or natural pool effect, greens, finishes that imitate mosaic, marble or stone, and textured membranes that hide small irregularities in the shell. We show you samples wet and in natural light, because colour changes a lot under the Costa Blanca sun, and help you combine floor, steps and waterline band so the result suits the house.

More jobs in this service

  • Non-slip liner for pool steps, benches and shallow areas

    On steps, benches and shallow areas we weld textured non-slip membrane, which grips wet feet without feeling rough. We can pick out the steps in a contrasting shade so they are visible from outside the pool, which is especially useful with children and older people.

  • Pool shell with hairline cracks beyond patching

    When a concrete shell has many hairline cracks and a new one appears every season, a reinforced membrane waterproofs the whole surface at once. First we check that water is not escaping through pipes or built-in fittings, which is a job for leak detection.

  • Reinforced PVC liner for freeform pools

    Kidney shapes, curves, islands or rounded steps are no problem: the membrane is cut and welded on site to fit each shape, with neatly finished overlaps and no bagging, something a prefabricated liner cannot achieve in irregular pools.

  • Reinforced PVC liner over a fibreglass pool

    Prefabricated fibreglass pools eventually end up with a cracked gelcoat, blisters or leaks through cracks. We sand, reinforce weak points, lay geotextile and weld the reinforced membrane over the shell, which becomes watertight and looks new without replacing the pool.

  • Liners for above-ground and wooden pools

    Above-ground pools made of wood or steel panels need a liner cut to the exact shape. We have it made to measure, hang it from the top rail and settle it carefully so it does not crease on the floor or pull at the corners.

  • Wrinkled pool liner or water trapped behind it

    Wrinkles appear when the liner has stretched, when the pool was drained carelessly or when water gets between the liner and the shell. We find the source, reposition or replace the liner and check the floor drainage so they do not form again.

  • Patching a cut or puncture in a pool liner

    A pine branch, a sharp object or a jammed pool cleaner can cut the liner. If the rest is sound, we fit a patch of the same material, underwater when the cut is small or welded with the pool empty if it is in an awkward spot.

  • New flanges and gaskets on skimmers, jets and lights

    Every time a liner is replaced, the gaskets must be renewed and the flanges on all built-in fittings properly tightened. This is where most leaks appear after a poor installation, so we fit new ones and check they are watertight while the pool fills.

  • Reinforced liner without lifting the coping

    To avoid breaking edges that are in good condition, we fix an anchoring rail to the wall just below the coping and weld the membrane to it. The finish is clean and hidden, and the surround and edges are left untouched.

  • Rusty steel panels behind the pool liner

    In panel pools, rust appears when water gets in behind the liner. We take out the liner, treat or replace the affected panels, protect the whole structure and fit new underlay and a new liner so the problem does not recur.

  • Pool liner stains: pine needles, metals or limescale

    Leaves left on the floor, too much of certain metal-based products and limescale all leave stains on the liner. We use a cleaner made specifically for PVC and, if the stain has penetrated the material, replace that area by welding in a new sheet or renew the membrane.

  • Reinforced PVC liners for community pools

    For communities, a reinforced membrane avoids repainting the shell every year and cuts repairs between seasons. We choose light colours that keep the floor clearly visible, add non-slip areas on the steps and schedule the installation so the pool opens on time.

  • Liner replacement at holiday apartments between seasons

    At holiday apartments and small hotels on the coast, the pool must always look its best. We renew the membrane in the quieter months, with a clean job and no demolition, so the change does not affect bookings.

What you get with us

  • No chipping off or demolition

    We install over the existing lining, with much less rubble, noise and dust in the garden and a shorter job than any rigid lining replacement.

  • A watertight lining with no grout joints

    The welds form a continuous, waterproof surface with no joints for limescale and algae to cling to, which really helps with the hard water in Alicante.

  • Fixed written quote

    We itemise the metres of membrane, the substrate preparation, the rails and the parts being replaced, at a price that does not change once work starts.

  • Reply within 24 hours in season

    If your liner tears in mid-summer, we reply within 24 hours in season and assess with you whether a patch will do or it needs replacing.

How we do it, step by step

  1. Measuring and inspecting the shell

    We measure the pool point by point, check the substrate and built-in fittings and find the cause of the wear on your current lining.

  2. Choosing membrane and colour

    Together we choose the type of membrane, the colour, the texture and the non-slip areas, and send you a proposal with every item set out in detail.

  3. Preparing the substrate

    We drain the pool, remove loose tiles or flaking paint, level the shell, lay the geotextile underlay and fix the anchoring rails around the entire perimeter.

  4. Welding and installation

    We weld the membrane with hot air, seal the overlaps with liquid PVC and fit flanges and gaskets on skimmers, return jets and lights.

  5. Filling and start-up

    We fill the pool while making sure the membrane settles without creases, check every fitting is watertight and balance the water to protect the PVC from day one.

Liners and PVC membrane in Alicante province

The Costa Blanca has a huge number of concrete pools from the seventies and eighties with tired mosaic tiles and painted shells that need repainting every season, and a reinforced membrane suits them perfectly because it renovates without demolition. It is also the solution most appreciated by owners of holiday homes in Calpe, Altea, Jávea or Dénia who spend half the season away: a short, rubble-free job that leaves the pool ready for when they arrive or for letting it out in summer.

The climate of the province shapes the choice. Strong sun and long hours of daylight punish the band above the waterline, so we recommend membranes with UV protection and always keeping the water at the correct level. Hard water leaves less trace on a surface without joints, and on urbanisations with pine woods it is worth clearing needles often so they do not stain the floor. At hillside villas with sea views, sand and white tones give that turquoise that blends into the Mediterranean; inland, greys suit the stone and scrubland.

Where we do it

Swimming pools in Elche and Santa Pola

The Camp d'Elx, with its houses among pomegranate orchards and palm trees, and the coast from Arenales del Sol to Santa Pola call for very different pools. We build in the countryside, renovate villas and look after the water for people who only spend part of the year here.

Frequently asked questions

What people ask us most about liners and PVC membrane.

Liners and PVC membrane: your questions

What is the difference between a pool liner and a reinforced PVC membrane?

A liner is a PVC bag made to measure and hung from a rail around the edge; it is thinner and mainly used in panel and above-ground pools. A reinforced membrane is thicker, has an internal reinforcing mesh and is welded on site over the shell, adapting to any shape. For concrete pools with old tiles or paint, the reinforced membrane is the toughest option.

Can a reinforced liner be fitted over pool tiles?

Yes, and it is the most common approach. There is no need to remove the tiles: we take off any loose or sharp ones, fill the gaps, level the surface and lay a geotextile underlay that protects the membrane and cushions irregularities. Then we fix the rails and weld. The tiles stay underneath as a base and the pool gains a continuous, watertight lining.

How long does a reinforced PVC pool liner last?

Many seasons if it is looked after. What shortens its life most is poorly balanced water, with low pH or high chlorine, leaving it empty in the sun and knocks from sharp objects. Keeping the chemistry stable, removing leaves often and not draining unnecessarily are the habits that extend its life most. If it ever gets cut, it can be repaired with a welded patch without replacing the whole membrane.

Can I drain a pool with a liner?

Best not to unless it is necessary. PVC shrinks when left without water and in the sun, and it can pull away from the rails, wrinkle when refilled or even tear. If the pool has to be drained for a repair, we do it in a controlled way and keep it empty for as short a time as possible. There is no need to drain it for the winter: just keep the water in and winterise it properly.

Is a reinforced pool liner slippery?

The smooth membrane on the floor is no more slippery than mosaic tiles, but on steps, benches and shallow areas it is worth fitting textured non-slip membrane, which grips wet feet. We weld it in those areas and combine colours so the steps stand out clearly. For community pools and holiday accommodation it is something we always recommend.
