Beauval Zoo: waterproofing on metal roof panels

The Beauval Zoo is an ambitious wildlife leisure park project which features an equatorial dome, one of the its impressive elements. With a height of 38 meters and a diameter of 100 meters, the circular building has a floor area of approximately 14,000 m2, along with a 1700 m2 roof terrace above the restaurant area that borders the greenhouse. To waterproof this external section, a solution was needed that would be adapted to the metal panel load-bearing parts and which would meet the requirements of speedy project management (the entire zoo was built in only 2 and a half years).

To waterproof the roof terrace, we proposed the application of our double-layer bituminous waterproofing solution made up of Paradiene FM and Paracier G. The advantage of this solution is that it delivers excellent performance in terms of wind and fire resistance, and it can be adapted to metal roof panels. The first waterproofing layer Paradiene FM was thus mechanically attached to then accommodate the Paracier G layer which was fully welded. Implementation took only one month, so the solution perfectly met the tight deadlines of the site.
