Problems with shell pools.
Polyester hulls age badly if not treated in time. Blisters, cracks or loss of watertightness are signs that should not be ignored. Here are the most common signs observed by our customers.
Visible blisters on the walls
Classic symptom of osmosis. They can grow and cause cracks.
Structural cracks or microleaks
They may go unnoticed, but they cause water loss and weaken the hull.
Flaking paint or gelcoat
The coating becomes porous, rough and loses its waterproofing properties.



Our solutions to save your hull.
Forget about replacing your entire hull. Our exclusive protocol allows us to install a reinforced liner perfectly adapted to your polyester hull. A watertight second skin that hugs every curve, masks every flaw and transforms your pool for a fraction of the cost of replacement.
Exclusive anti-osmosis protocol
Complete treatment of the hull before installation: osmosis neutralization, controlled drying, separation geotextile. Your hull will be in good shape for at least 20 years.
Perfect adaptation to complex shapes
The reinforced liner is not just a simple bag. Cut and welded on site, it fits perfectly around molded stairs, curves, and free forms. The result: no folds and perfect tension.
Massive savings guaranteed
5 times less expensive than a complete replacement. 10-year waterproofing warranty, a choice of 15 colors, and a pool that's even more beautiful than the original. The smart investment for your pool.



What are the steps involved in installing a liner when renovating a fiberglass pool?

Analysis of hull and parts to be sealed
We carry out a complete assessment of the hull: looking for signs of osmosis, cracks, delamination, compatibility of existing parts to be sealed (skimmers, projectors, nozzles, etc.).

Sanding, treating defects and applying felt
We clean the surface of the hull, remove any areas affected by osmosis with appropriate sanding, then treat sensitive areas. Once the surface has been cleaned, we lay a protective felt over the entire pool (bottom and sides) to create a healthy, insulated base ready to receive the reinforced liner.

Laying the reinforced liner on the hull
We fit and weld the reinforced liner to the existing hull, for a long-lasting, aesthetic result. The pool is back in the water in no time.
