Reinforced membranes: performance, design and watertight confidence for every pool
At RENOLIT ALKORPLAN, we understand that a swimming pool finish is not only about appearance. It also plays a key role in the pool's performance, durability, watertightness and long-term maintenance. This is why reinforced membranes have become one of the most widely used pool waterproofing systems worldwide. Their easy installation, attractive design possibilities, watertight performance and long-lasting resistance make them a reliable solution for both new pools and renovation projects.
Designed to protect the pool over time
A swimming pool is exposed to constant use, water, sunlight, temperature changes and chemical products. For this reason, its lining must offer both watertightness and long-term resistance. Reinforced membrane technology helps prevent common problems such as water loss caused by cracks in the pool structure or by joint sealing failures. Unlike porous materials such as concrete, a reinforced membrane creates a non-porous lining that helps keep the pool watertight and supports its correct performance over time.
Manufactured with several layers, including reinforced polyester and PVC, these membranes provide resistance to impacts, corrosion and temperature variations, while reducing the need for constant maintenance. Compared with traditional finishes such as mosaic tiles, which can crack, wear down or require frequent repairs, they offer a practical alternative designed to protect the pool and preserve its appearance for many years.
2 mm thickness for a more refined finish
One of the key features of RENOLIT ALKORPLAN's premium reinforced membranes is their 2 mm thickness. Combined with the Testa welding technique, this allows installers to achieve an almost invisible seam, creating a cleaner and more continuous finish in the final pool. The result is a solution that performs at the highest level both technically and aesthetically: a resistant, reliable membrane with an excellent design finish that enhances the overall appearance of the project.
Fast installation, expert support and exclusive design
Reinforced membranes can adapt to any pool shape, size or existing material, making them a versatile solution for both new construction and renovation. Unlike systems that require piece-by-piece installation, the membrane is applied as a continuous lining that adapts to the pool surface. Installation is fast and clean. In many cases, the process can be completed in just two or three days, reducing disruption for the client. Its smooth, non-porous surface also helps prevent the accumulation of dirt, algae and chemical residues, making regular maintenance easier over time.
Product quality also depends on proper installation. That is why we work with trained and certified installers, helping ensure that each membrane is applied correctly and that the final result meets the expected standards of performance, watertightness and finish.
