Waterproofing & Roofing
We have excellent knowledge of all waterproofing and roofing technologies for professional buildings. Yet, we wish to focus your attention on a solution that simultaneously addresses many issues: the all-in-one waterproofing + EPDM (ethylene propylene diene monomer) roofing solution. You can even add a photovoltaic (if the roof permits) or a vegetative solution, based on your clients' desires.

A Closer Look at EPDM

EPDM offers unquestionable end-user advantages over traditional asphalt roofing technology.

 EPDM roofing is resistant to any kind of dilatation, and the material has 300% elasticity when new and 250% elasticity after 30 years. It is a real asset considering that the majority of terrace roof waterproofing problems are the result of the dilatation of the different materials used.

 Its molecular structure is stable: EPDM is a chemically inert material. Therefore, it is resistant to UV rays and nearly resistant to pollution, acid rain and other corrosive a matter of interest, EPDM is used to waterproof tanks for liquid manure, which is one of the most corrosive natural products around.
 Contrary to many other materials, EPDM is 100% recyclable.
 The EPDM installed by BRIDAULT SOLLUTIONS can be delivered by Firestone
in large, single sheets to reduce the number of joints:

a single, monolayer strip can be used on a 300 m2 (3200 sq. ft.) rectangular roof, instead of using the standard 30 x 10 m2 (108 sq. ft.) strips and creating nearly 300 m (1000 ft) of linear joints that would increase the risk of leakage.

subsequently, it is easier to reinforce chimneys.
  EPDM waterproofing is at least three times more durable than asphalt: for example, the Chicago Airport was redone in EPDM in 1962. There have not been any repairs since.
  As an example, it is possible to maintain heavy protection (using gravel) and decide in two years to replace the gravel with a vegetative roof. There would be no need to change the EPDM membrane, which is compatible with vegetative roofing practices and naturally provides a root barrier.
  Fire risk is eliminated, since EPDM is welded using vulcanisation (i.e. no flames or blow lamps). In the event of a fire, EPDM does not drip, but rather retracts.
  EPDM can be used independently (weighed down by gravel or vegetation), semi-independently or with adhesive (over old roofing).
 When weighed down, EPDM is very competitive vis-à-vis older technologies: even though it is more expensive, installation is quicker.
   EPDM is a solution that has proved its worth to demanding decision makers who wish to protect their assets, such as BRIDAULT SOLUTIONS’ large industrial clients.
   EPMD's 1.4 kg/m2 is particularly well suited to renovations performed on weak frames and helps maximise insulation thickness.
