Alkorplan 3000: Stone and Marble Effect Reinforced Membrane for Your Pool
The Alkorplan 3000 collection is Renolit's answer for anyone who wants a pool with character without giving up the reliability of standard reinforced membrane. We are talking about a stone and marble effect reinforced membrane that is 1.5 mm thick, with exclusive double-lacquered prints reproducing mineral textures such as Carrara marble or natural stone. At ARG PISCINAS, official Renolit Alkorplan installers with over 15 years of experience, we recommend it to clients seeking a premium look at a standard-range price.
What the Alkorplan 3000 collection is
Alkorplan 3000 is a range of PVC reinforced with polyester mesh, the same high-performance material that defines the entire Alkorplan family. The membrane consists of two layers of PVC bonded to a reinforcing weave that provides dimensional stability and tear resistance. What sets this collection apart is its finish: the designs are not a simple solid colour but printed patterns protected by a double-lacquer coating that recreates veins, tones and depth typical of stone and marble.
- Thickness: 1.5 mm (Alkorplan standard range).
- Reinforcement: internal polyester mesh.
- Finish: prints with a protective double lacquer.
- Aesthetic: natural stone and marble effect.
- Installation: hot-welded over geotextile and profiles, forming a continuous, watertight membrane.
Available models: Marble, Carrara, Bysance Blue and Persia Sand
The collection offers four designs intended for different pool styles and surroundings. Each conveys a different sense of the water depending on its base tone.
| Model | Aesthetic | Water colour | Ideal for |
|---|---|---|---|
| Marble | Light marble with soft veining | Bright, clean blue | Classic, luminous pools |
| Carrara | White Carrara-type marble | Elegant turquoise | Contemporary, luxury designs |
| Bysance Blue | Mosaic/stone in blue tones | Deep, intense blue | Mediterranean, traditional style |
| Persia Sand | Warm sand-coloured stone | Natural green-sand | Rustic settings and lagoons |
The chosen model completely shapes the visual result. If you are torn between options, our projects show how each finish behaves underwater and under the real light of each garden.
Benefits of the double lacquer and who it suits
The main selling point of Alkorplan 3000 is its double lacquer. This extra protection over the print provides greater resistance to abrasion, UV rays and chemical products compared with a single printed finish, helping the design keep its sharpness for longer. It is the perfect option for those who want the sophisticated look of stone or marble without the cost of the 2 mm premium ranges.
- Premium look at a standard-range price: marble and stone effect without paying for the 2 mm thickness.
- Greater print durability: the double lacquer protects the design against everyday wear.
- Continuous, watertight membrane: hot-welded, with no vulnerable joints like a liner or mosaic tiles.
- Versatility: suitable for both new pools and renovating old pools, adapting to any shape.
It is ideal for families renovating their pool who want a striking aesthetic upgrade, for villas seeking to stand out and for developments that need a prestige finish on a controlled budget. Discover all the possibilities on our services page.
Professional installation of the reinforced membrane
The performance of any Alkorplan membrane depends on both the material and the installation. At ARG PISCINAS we prepare the substrate, lay the protective geotextile, fix the perimeter profiles and hot-weld every overlap until a fully continuous membrane is formed. This process guarantees watertightness and prevents leaks over the long term.
- For new builds: reinforced membrane installation in new pools.
- For renovations: reinforced membrane installation in old pools, an ideal solution for recovering basins with deteriorated mosaic or peeling paint.
Maintenance and durability
One of the great virtues of Alkorplan 3000 is its low maintenance. The surface of the reinforced PVC is smooth and barely porous, which makes it hard for algae and limescale to adhere. With a correct chemical balance of the water and regular cleaning, the membrane keeps its appearance for many years.
- Keep the pH between 7.0 and 7.4 and chlorine at appropriate levels so as not to attack the lacquer.
- Use the pool cleaner regularly and brush the water line to prevent build-up.
- Avoid abrasive or concentrated products applied directly onto the membrane.
- A good installation over geotextile extends the service life and watertightness of the whole.
With these basic care steps, a well-installed reinforced membrane offers a long service life while keeping the colour and texture of the print practically intact.
Frequently asked questions
What is the difference between Alkorplan 3000 and the premium ranges?
Alkorplan 3000 is the 1.5 mm standard range, while the premium ranges are 2 mm. The 3000 offers double-lacquered prints with stone and marble effect at a more affordable price, ideal when you prioritise aesthetics on a tight budget.
Does the marble effect look the same underwater?
Yes. The print is designed to be enhanced underwater: the model directly influences the final colour, from Carrara's elegant turquoise to the intense blue of Bysance Blue or the green-sand of Persia Sand.
Can I install Alkorplan 3000 over an old mosaic-tiled pool?
Yes. It is one of the best solutions for renovating pools with deteriorated mosaic or watertightness problems. The membrane adapts to the shape of the basin and creates a continuous membrane without demolishing the previous coating.
How long does the double-lacquer finish last?
The double lacquer provides greater resistance to abrasion and UV rays than a simple print. With correct water maintenance, the design keeps its sharpness for many years.
