Now that we are officially close to the beginning of the summer, although the time makes us think that it started some weeks ago… this is the perfect time to tune up the swimming pools so we will avoid future surprises.

If you are those who keep all the year the swimming pool with water and with its proper maintenance, surely you are already enjoying it.

On the other hand, if you prefer to leave the water without treatment once the summer ends and therefore you save the maintenance costs (remember that the filter system, the chlorine, etc. are a monthly expenditure). Now you should get down to work, empty the swimming pool, clean it and the filter system completely with especial products and fill it with water again to enjoy it.

But, what happens if your swimming pool leaks water because it is much damaged or simply it is disused and needs restoration?

In this point, to tune up your swimming pool, it is not enough with a simple cleanness… it is needed some reparation and we recommend the reparation with a PVC sheet.

Why a PVC sheet?

The PVC is a type of plastic which is ideal for the reparation of swimming pools because of its long service life, its waterproofing, its easy transportation, installation and handle.

Besides of being colourless, odourless, insipid and much more economical than other products for swimming pools, it provides an excellent final result.

Now that you know why the PVC is the best option, we are going to explain how it is done the whole reparation process of a swimming pool.

1. Find possible leaks.

The first thing that should be done is the appropriate testings to find exactly where it leaks water, if it is through the duct of the swimming pool or through the pipe system.

That’s why there are several methods, as it can be the colouring powders or the pressure tests in the case of the pipes.

2. Change the pipe system and the fittings of the swimming pool.

When it is substituted the old fittings that could be broken, or which don’t work… and the pipe systems of the filter, we make sure that water will not leak, that all will work correctly and that the waterproofing PVC sheet will fulfil its function.

3. Collocation of the upper profiles where the PVC sheet will be fixed.

Some top profiles are installed (that they should be also made of PVC as the sheet will be joining to them through the thermofusion welding.

These profiles, besides fixing the sheet, will avoid the possible cracks and will avoid the water leaks.

4. Installation of the PVC sheet.

This is the most important process of the whole reparation as the sheet will waterproof the swimming pool.

The installation of this sheet is manually done and to join all its parts it is used the manual thermofusion welding with hot air.

This type of welding assures the 100% of the join of the whole parts of the sheet, as when they are welded with heat, the physical properties of the PVC are joined making the weldings a complete sheet without leaks.

For this type of weldings it is used a manual welder, an especial nozzle for the overlapping of the sheet and a roller to apply the proper pressure for the join.

It must be installed the whole sheet across the length and breadth of the swimming pool, covering correctly stairs, walls, floors, etc. to achieve a good result.

5. Collocation of the frames of the fittings

The fittings that we have changed in the 2 step have some frames with joins and screws to guarantee the tightness of the swimming pool.

So now that we have already installed the sheet, these frames are collocated and so we have the system totally ready.

Now, we only have to seal the upper edges of the PVC sheet with polyurethane putty and now you have the swimming pool totally ready to enjoy an unforgettable summer.
