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 elements...as 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. |
