FAQ – Changing liner and reinforced PVC

When should I plan to change my liner?

Usually every 10 to 15 years. However, if you notice that the liner is becoming “brittle”, that it is wrinkling abnormally or that the water line is tearing, don’t wait for a leak. A preventive intervention costs less than repairing a flooded structure.

How much does a liner change cost in Geneva or Vaud?

Prices depend on the surface area of the pool, its complexity (steps, shapes) and the collection chosen. On average: – ALKORPLAN 2000 / RELIEF / ALIVE: economical and intermediate ranges (10-year warranty) – ALKORPLAN TOUCH / VOGUE: premium ranges with 15-year warranty – ALKORPLAN CERAMICS EVOLVE: exclusive ceramic-effect collection

What’s the difference between liner and reinforced PVC?

The classic liner (0.75mm) is a prefabricated pocket suspended from the rails. Reinforced PVC (1.5mm) is custom-welded directly into the pool. It’s 2× thicker, more resistant to UV rays and chlorine, and lasts 15-25 years versus 10-12 years for a liner.

Can I change the color of my pool water?

You bet! It’s the perfect opportunity to go from classic blue to modern gray, lagoon sand or mirror black. Each membrane shade produces a different water color.

How long does it take to install reinforced PVC?

For a standard pool (8×4m), allow 3 to 5 days’ work: – Day 1: Drainage and removal of old liner – Day 2: Substrate preparation, fungicide treatment – Day 3-4: Felt laying and welding of reinforced PVC – Day 5: Start-up and final inspection

Is reinforced PVC compatible with salt water (electrolysis)?

Yes, all Renolit Alkorplan membranes are compatible with salt treatment systems. They are also resistant to heated water up to 32°C, ideal if you have a heat pump.

Do I have to empty the pool to change the liner?

Yes, a complete draining is necessary. This is an opportunity to check the condition of the parts to be sealed (skimmers, nozzles, projectors) and replace them if necessary.

What is the warranty on Alkorplan reinforced PVC?

Collection Watertightness guarantee
ALKORPLAN 2000 10 years
ALKORPLAN RELIEF 10 years
ALKORPLAN ALIVE 10 years old
