Alkorplan Relief: Anti-Slip Reinforced Liner for Safe Pools

2026-05-31

The Alkorplan Relief collection is Renolit's answer for anyone looking for an anti-slip reinforced liner without giving up on design. It is a polyester-mesh-reinforced PVC membrane with a 3D textured embossed surface, designed specifically for the areas where water, bare feet and the risk of slipping meet: edges, steps, first treads, pool beaches and splash zones. At ARG PISCINAS, official Renolit Alkorplan installers with over 15 years of experience, we explain why this range is one of the best safety decisions you can make for your pool.

What is Alkorplan Relief and why it is different

Unlike smooth reinforced liners, the Relief collection features an embossed relief on the top layer of the membrane. This relief is not merely decorative: it creates micro-ridges that increase friction for bare feet on the wet surface, drastically reducing the risk of slipping. The membrane keeps the same structure as the rest of the Alkorplan ranges: polyester-mesh-reinforced PVC, heat-welded over geotextile and profile to form a continuous, 100% watertight membrane.

The Relief liner has a thickness of 1.8 mm, a reinforced gauge that sits between the standard liner (1.5 mm) and the premium one (2 mm), adding strength and durability in high-traffic areas. Like all Alkorplan reinforced liners, it comes with Renolit's 10-year watertightness warranty.

Anti-slip certification: real safety, not marketing

What sets Relief apart is that its anti-slip capacity is certified through independent tests with bare feet on a wet ramp (ramp method) and pendulum friction. It exceeds the most demanding European and international standards:

• DIN 51097 Class C: the highest class for barefoot areas (Class C covers surfaces with an incline over 24 degrees).
• UNE 41901 Level 3: the maximum level of the Spanish standard for pool coverings.
• EN 16165 Class C: the updated European reference for slip resistance.

This certification is especially relevant in public, community and residents' association pools, where safety compliance is not optional. It also brings huge peace of mind to families with children and to older people in residential pools.

Available models and colours

The Relief collection offers a wide palette that combines safety and aesthetics, so you can protect the risk areas without sacrificing your pool's design. The available models are:

One of the great advantages of the Alkorplan reinforced liner is that you can combine Relief with other ranges in the same pool. The most common and advisable strategy is to line the main basin with a smooth or design collection (such as Touch, Vogue or Original) and apply Relief on steps, the first tread, the relax bench and the pool beach. This way you get the best of both worlds: aesthetics across the whole and safety where it truly matters.

Which pools and clients it is ideal for

The Relief range fits especially well in these cases:

• Families with children: edges and steps are where most slips occur.
• Community and public pools: compliance with the required anti-slip regulations.
• Pools with a beach or splash zone: heavily used shallow surfaces.
• Spa, hydromassage bench and built steps: maximum grip at every step.
• Older people or those with reduced mobility: extra safety when getting in and out of the water.

If you are considering renovating your basin or building a new pool, in our covering services we integrate Relief both in installation in new pools and in refurbishment of old pools, where it replaces deteriorated tiling or coverings without building work.

Maintenance and durability

The Relief liner is as easy to maintain as the rest of the Alkorplan range, with one small nuance: because it has relief, slightly more frequent brushing is advisable in the textured areas to prevent dirt or biofilm from building up in the micro-ridges. Key recommendations:

• Maintain the water chemical balance (pH 7.2-7.6 and stable chlorine) to preserve the membrane.
• Regularly brush edges and steps with a non-metallic bristle brush.
• Use a specific PVC cleaner for stains, never abrasive products.
• Periodically check the profile and welds.

Properly installed and maintained, the membrane offers a service life of 15 to 20 years, with that 10-year watertightness warranty backed by Renolit. You can see real examples in our projects section.

Frequently asked questions

Does the Alkorplan Relief texture bother you when walking or swimming?

No. The embossing is a soft micro-relief: it provides grip for bare feet without feeling rough or uncomfortable. It is designed precisely to be used barefoot in bathing areas.

Can I use Relief only on the steps and another range elsewhere?

Yes, this is the most recommended and common approach. Since the whole membrane is heat-welded, we can combine Relief on steps, the first tread and the beach with a smooth or design liner in the main basin, forming a single continuous membrane.

What is the difference between Relief and the Touch anti-slip range?

Both are anti-slip, but Touch offers premium decorative finishes with more pronounced relief and high-end aesthetics, while Relief prioritises the certified Class C anti-slip function with a wide colour palette at a more adjusted cost. We advise you with no obligation on which one fits your project.

Is it suitable for community and public pools?

Yes. Its UNE 41901 Level 3 and EN 16165 Class C certification make it ideal for meeting the anti-slip safety regulations required in public and community pools.
