How to refurbish old concrete pools
Older, typically concrete, pools can become obsolete as they age. Our RenovAction® technology, using the Myrtha Pools modular, engineered system, is ideal for swimming pool refurbishment. Depending on pool condition, it may be the walls, the floor or the entire pool structure that has deteriorated and needs to be replaced. Our flexible technology allows us to refurbish only the areas that are failing and can often be carried out without any significant demolition.

Our chromium-rich stainless-steel alloy offers both the strength and resistance to chemicals and corrosion needed in a pool environment. To ensure a long life, structural elements like clamps, guides, panels and ducts are securely bolted together – not welded, as steel welding can leave the framework susceptible to corrosion.
For waterproofing, we use a strong PVC laminate that is resistant to UV rays and chemical agents, it can be cleaned easily and feels good to the touch. To ensure a complete, water-tight seal, a PVC liquid is used to bond all floor and wall panel joints and is used in all new Myrtha Pools and RenovAction® projects.
As with a new Myrtha Pool, RenovAction® projects are approached with design and functionality in mind. Finishing touches in a pool refurbishment not only help complete the pool design but also serve a practical purpose. Covering the top edge of the pool with mosaics or tiles protects the wall beneath while also giving the opportunity to introduce creativity and customization.
Myrtha Skin for the pool floor
Among the most important recent technological developments at Myrtha Pools is the arrival of Myrtha Skin. A pool which features a structure composed entirely of stainless steel brings distinct advantages to architects and designers. Using standard Myrtha technology on the sidewall panels and the new Skin for flooring is a simple and effective way to achieve this goal. Myrtha Skin is created by the same hot-calendering technique used to fuse the stainless steel and rigid PVC on our standard sidewall panels. The difference is that with Skin, the thickness is only 1 mm. That’s half the thickness of our sidewall panels. This slender 1-mm steel thickness allows for Skin to be especially flexible and adaptable. It will arrive at the construction site in coils, ready to be unrolled and then installed on the floor of the pool. To meet the non-slip standards freqently required for the bottom of pools, Myrtha Skin can be produced with either a textured or smooth surface. The textured surface version was developed by Myrtha Pools in accordance with European safety standards and is composed of a mix of liquid PVC and crystal.
Stainless-steel clamps are used to support pool structure. Fixed to the pool wall, clamps may be recessed into the wall should it be critical to maintain the dimensions of the existing pool.
In some cases, modifying the design of the pool structure is required to correct uneven or disconnected walls. In these projects, we apply a high-density foam spacer between the original structure and the Myrtha panel.
The stainless-steel panels that form pool walls are hot-rolled with a protective and waterproof PVC laminate. This creates a unique product which, because it is mechanically processed, can be bent and formed without any effect on the integrity of the PVC membrane. The Myrtha modular stainless-steel panels are then positioned in the pool tank with a specialized clamp system.
Once installed, the modular structure of the RenovAction® pool is waterproofed with a combination of semi-rigid PVC profiles and a special Myrtha sealant. Applied to all joints of the wall panels, this sealing process ensures a water-tight bond across the entire surface.
The pool gutter is manufactured from the same Myrtha stainless steel as the wall panels and can be customized to fit the structure being renovated. Gutters can be installed on the pre-existing housing or placed on the pool’s edge. Myrtha offers several gutter system options that include skimmers, overflows, infinity edges, waterfalls and more. You can explore all our skimmer technology here.
The floor of the new pool is lined with a special reinforced PVC membrane. The membrane is supplied in rolls, which are hot welded at the seams. The wall panels and the floor are joined together by a PVC profile or strip, which is also hot-welded to the walls and floor.
The joints between panels and overflow gutters are reinforced with a liquid PVC bond or PVC tape. This provides waterproofing and creates a smooth, uniform pool surface.
Ceramics, mosaics, glass tiles and other finishes introduce colour and design options to the pool renovation. These finishes can all be applied to PVC panels with long-lasting results.
