A perfectly waterproof rooftop or balcony to enjoy the pleasures of life.

Creating a rooftop or making a balcony perfectly waterproof will bring you a lot of happiness! Doing your yoga session in the morning, reading in your deckchair in the afternoon or welcoming your friends in the evening, or even installing a swimming pool, it’s great! A rooftop the way we like it! See the result on the rooftop terrace of the Hotel Jam.

To enjoy it for a long time and without worries, demand a quality premium waterproofing. It prevents rainwater infiltration, thus avoiding concrete corrosion, carbonation, unsightly moisture stains, cracked tiles, leaks etc. . Remember also that the loads on an accessible roof terrace are heavier. It would be a shame to have to dismantle your finest stone, tiles, slabs or wooden slats.
