Commercial pool renovations

After the pandemic closures, commercial aquatics facilities might have been confronted with peeling, cracking or leaking pools. A feasible solution to these chronic problems is to line these pools with an on-site PVC membrane.

Not only is the weld-in-place liner very affordable, but also can it eliminate some underlying issues in the pool’s structure to make it completely watertight. A PVC membrane thoroughly seals the pool structure, and is thus the perfect solution for commercial pool renovations.

It’s also important to consider that on-site pool liners are suitable for both renovating existing pools and building new aquatics facilities. They can be used to line a new concrete wall or stainless-steel pool wall construction, or to line a cracked, peeling, or leaking gunite, plaster or fiberglass pool.

 

Why choose a PVC pool membrane for commercial pool renovations

  • Thanks to its protective lacquer, they are chlorine and UV resistant. Its outstanding performance shows also in conditions of chemical abuse.
  • Instead of dealing with long lead times for pre-manufactured products, weld-in-place pool membranes are readily available. Pool liner installers can overcome lead times by stocking the PVC membranes for upcoming jobs.
  • Weld-in-place pool liners provide a perfect fit for any pool shape. Since they are installed on-site, you can get an exact fit even for the most challenging shapes.
  • Because of the mesh reinforcement between the layers, they perform great longevity and tear-resistance.
  • The surface underneath the PVC membrane can continue to shift and crack but it won’t affect the membrane. This of course gives peace of mind to any aquatics facility manager.
  • Due to its low maintenance, aquatics facility managers will see their pool maintenance costs decrease in terms of money and time.
  • In both 60- and 80-mil thicknesses, they come in beautiful textures that will give pools not only watertightness, but also a completely renovated look in a trendy design.
  • Talking about design, these reinforced pool liners can be found in various textures and prints that resemble natural elements such as marble, stone and sand. Going beyond the plain white or blue, these options are popular among hotels, country clubs, homeowners associations and community pools because they provide a more high-end feel.
  • Forget the old anti-slip texture for steps and shallow water areas. Slip resistant does not mean old-fashioned knobbly texture anymore.

After having seen the various advantages an on-site pool liner bears within itself for commercial pool refurbishment, let’s have a look at how to install it.

Understanding PVC pool membrane installation

The installation process of a weld-in-place membrane is relatively straightforward. These are the steps to follow:

Preparing the surface

Before installing the pool liner, crews have to prepare the surface, which can include repairs. In terms of time, most pools require a day or even less for preparation.

Nonetheless, if a pool is in particularly bad shape, it might need three to four days for fixing the surface.

Installing the felt linig

Once the surface is ready, a felt lining aka geotextile is installed on the pool shell.  Thanks to its anti-bacterial properties, it avoids bacteria proliferation behind the PVC membrane, thus extending the life of the product.

As a side benefit, the felt lining conveys a cushioned feeling to the surface making the floor more comfortable to stand on. This is specially important in wading pools and also when using the commercial pool for water conditioning, therapy or aerobics.

Installing the weld-in-place liner

After the geotextile is installed, 6-foot-wide strips of PVC pool membrane are rolled out and heat-welded together on site. Steps, beach entries, safety ledges and any other shallow water areas are cut, fitted and welded as well.

Slip-resistant, embossed surfaces have to be used on steps, shallow areas and beach entries. There is also black membrane to create racing lanes and depth markers.

How to weld reinforced pool liners

Because they are welded on site, this allows the greatest degree of customisation, and can help avoid supply-chain issues.

Depending on the part of the installation process, there are three different welding techniques.

Reinforced pool liners welding techniques

The two basic installation techniques are spot welding and traditional overlap welding. Contractors looking for a superior aesthetic finish also use the butt-welding technique along the pool floor to make the welds almost invisible.

Spot Welding

Spot welding takes place at the beginning of the installation to help position and secure the liner so that it does not move through the rest of the process.
Small, quick ‘pre-welds’ are made between the overlapping pieces at intervals of approx. 7 to 8 inches along the seam. During this process, the pieces must be perfectly aligned since the liner needs to be held in place.

Overlap Welding

For overlap welding the liner layers overlap by approximately 2 inches. This overlap will in the end turn into a 2-inch-wide seam.

Once the spot welds have been done, installers apply the welding gun down the full length of the seam. The welding nozzle is inserted under the overlap in order to heat both surfaces sufficiently to fuse the layers and form a lap. While the lap is still hot, pressure is applied with a silicone roller to ensure the two layers are fused together.

Robot welders are used to speed up the welding process for larger pools. Once the robot welder is set-up, it automatically welds the entire length of the pool.

Butt Welding

The butt welding technique is compatible only with 80mil membranes. This is specially recommended for more visible areas such as the pool floor in order to hide the seam.

Instead of overlapping the membrane edges, they are butt up against each other.

This technique is not compulsory at all, though it achieves virtually invisible joints on the pool floor.

Being more time-consumig, it will add to installation costs. That’s why some installers stick with the traditional overlap weld since in the daytime, when the water is moving, the overlap joint is not apparent.

As a result, the awareness of reinforced PVC pool membranes is definitely on the rise, specially among commercial aquatics facilities that need a renovation. After considering the different systems for commercial pool renovations, refurbishing them with an on-site pool liner becomes the long-lasting pool lining solution facility managers have been looking for.

Tile pool repair

Tile pool repair

Tile pool repair

This cracked and leaking pool located in Marbella needed an urgent repair. Poor construction and ground movement were to blame.

The pool had cracked across the width and from the middle towards one corner, what caused water leaks in the structure.  When the structure is leaking, regrouting or replacing the glass mosaic tiles will not help since they are not waterproof. 

Traditional tile pool repair based on using repair mortar or filling the cracks with silicone does not prove successful in the long term. You have to deal with the underlying problem because if the ground moves slightly again, the crack will reopen.

Once a pool starts cracking, there is no turning back: it needs to be repaired quickly to prevent more damage in the structure itself or even in the surrounding area. Not only will the steel in the structure become exposed and will start to corrode, but also will the water running under the pool structure soften the ground. Thus, the problem will further aggravate.

To sum up, even though mosaic tiled pools are an absolute eye-catcher, this pool lining option implies a series of disadvantages including dirty grout lines, loose or broken tiles, cut feel and difficult maintenance. RENOLIT ALKORPLAN CERAMICS, on the other hand, requires low-maintenance, is easy to clean and provides the beautiful finish of tiled pools.

Piscina Liner are pool specialists in Andalusia and Algarve with many years of experience in repairing cracked and leaking pools. Whenever they deal with a tile pool repair where the customer does not want to give up this aesthetic finish, they recommend RENOLIT ALKORPLAN CERAMICS.

“No more loose tiles, sharp edges, leaks and difficult maintenance.”

Applying a RENOLIT ALKORPLAN reinforced membrane over the existing pool shell creates a barrier for the water and is guaranteed to be waterproof. In this specific case, the landlords chose the distinguished light grey ALKORPLAN CERAMICS Selene in order to undergo the tile pool repair. Pools do not always have to be blue! All the beauty of a tiled pool with none of the downsides of a tiled pool.

Ever heard of the Slovene Riviera? The beautiful coastline of Slovenia is located on the Gulf of Trieste, by the Adriatic Sea. A charming location with charming households like this wonderful one embellished with a pool lined with ALKORPLAN TOUCH Prestige.

A private house located in the seaside resort and spa town of Portorose (Portorož), whose owners were having problems with the previous lining system, which had been installed back in 2005. The old 1.5 mm blue liner had been wrongly installed, what caused water leaks on many spots.

Spambient, a pool building company from Slovenia specialised in swimming pools and whirlpools was in charge of the complete pool repair on this occasion. Refurbishing a pool lined with reinforced membrane is very easy and it will not take more than a few days depending on the pool dimensions. That is exactly one of the many advantages of the on site lining: simple installation without additional building work.

Since the previous lining had also had problems of colour fading, this time the landlords opted for a pool lined with ALKORPLAN TOUCH Prestige: a 2 mm thick pool liner inspired by nature provided with great durability. A 3D relief which reproduces volcanic rock and perfectly matches with the red-coloured façade and the surrounding pool deck.

The 13.5 x 5.8 m overflow pool with a variable depth which ranges from 1.4 to 2.1 m, has four inbuilt underwater windows, an unusual but impressive pool design. It is also equiped with water attractions, a submerged pool roller cover and an inverter driven heat pump.

In a nutshell, a pool that stands out not only because of its wonderful setting with gorgeous seaview, but also because of the pool characteristics, that make it unique.

Panorama swimming pool in the Alps

Panorama swimming pool in the Alps

Panorama swimming pool in the Alps

The „Gruebi-Bad“ was inaugurated back in 1931. The hoteliers of Adelboden joined forces in order to build a 50m panorama swimming pool to seasonally adjust the tourism in this Swiss region. 

 

They commissioned the architect Beda Hefti in order to build this panorama swimming pool. He had already taken part in the construction of Alpine swimming pools in Interlaken and Gstaadt, and designed a functional, high-quality open-air swimming pool following a timeless style and fitting it into the hillside.

Today, almost 90 years later, and after a complete refurbishment, this panorama swimming pool looks like it used to be on its opening day in 1931. Nonetheless, in 2011 it was close to a shutdown because the citizens of Adelboden rejected the refurbishment project, but luckily another refurbishment proposal in 2016 was accepted.

 

 

The last refurbishment of the panorama swimming pool took place in 2004 and limited itself to reducing the size of the pool to 25m because of the landslide. Since then the „Gruebi-Bad” was just the half of what it originally was and both diving platform and band shell had been removed.

In 2018 the panorama swimming pool was closed in order to start the refurbishing. Taking into account that the whole facility is under a preservation order, the following refurbishment works took place:

  • Renovation of the sanitary facilities.
  • Adjustment of the swimming-pool technology.
  • Rebuilding the children’s pool to its original round form.
  • Pool basin extension to its original 50 m and repairing the wall cracks.
  • Pool relining with RENOLIT ALKORPLAN XTREME Silver by the Swiss on-site liner installer Kiwi GmbH.
  • Rebuilding of both diving platform and band shell.
  • Mounting a one-of-a-kind overflow gutter.

Taking into account that this panorama swimming pool is located on a landslide where there is danger of slipping and it moves every year downhill, the architects of Architekturbüro Akkurat Bauatelier had to come up with an ingenious idea to solve this construction challenge. The gutter watergate had to be adjustable, so that the water would uniformly drain in spite of the inclined location of the pool. 

The alignment with the original design from Beda Hefti has given back its genuine splendour to the Gruebi-Bad since it now corresponds to the original state from 1931 except for some small details. We wish lots of fun to all the citizens of Adelboden and visitors in this reopened swimming pool, which is by the way one of the few 50 m open-air swimming pools in the Swiss Alps.
