The Clair Lagon concept
Clair Lagon is a story of nature, design, and shared pleasure — an elegant alternative to the traditional swimming pool. Our 100% fine-sand lagoons enhance gardens and transform them into genuine private beaches at home.
With their gentle slopes, our lagoons offer the perfect playground for children — between swimming and sandcastles.
The only company in Europe to create true natural-sand lagoons, we offer a unique experience: water that remains crystal clear thanks to our closed-loop filtration system — entirely chemical-free and easy to maintain.

How does it work ?
Our secret weapon : a unique filtration system
Our lagoons use a continuous gravity-based filtration system that renews all the water in just 1 to 6 hours, depending on size. The process unfolds in several stages: sand filtration, UV purification, and oxygenation through a cascading return flow.
Result : pure, crystal-clear water with no chemicals, and reduced water and energy consumption. Impurities are evacuated into a collection well connected to wastewater. To ensure optimal safety, water quality is checked in all facilities almost daily by the ARS.
Our services
At Clair Lagon, we support you far beyond the creation of your lagoon. From advice and landscaping to personalized follow-up, our services are designed to offer a unique, worry-free experience — from design to swimming.
Design : from inspiration to creation
Together, we design your tailor-made lagoon — shape, materials, and colors adapted to your site’s technical and regional constraints. We produce 2D, 3D, and technical plans.
We work with passionate landscape partners across France and Europe to create complete projects tailored to your expectations and desires.
Construction : execution and quality control
We operate year-round, summer and winter alike. Depending on the size and configuration, a lagoon takes 4 to 12 weeks to complete. A site manager oversees the project from start to finish.
We also work with partner companies for pool removals.
