Waterproofing your flat roof is crucial, but using flame is risky and can cause serious safety and environmental issues. Fortunately, there’s an alternative: the Drylast CRWP® Flame-Free Liquid Waterproofing System (LWS).
The dangers of using flame on a roof
On the roofs of industrial, logistics, or commercial buildings, using a torch turns every intervention into a high-risk zone. Its open flame can ignite a fire when it comes into contact with sensitive materials or flammable gases, leading to serious human and material consequences.
For certain buildings, such as ICPE (Installations Classified for Environmental Protection) or ERP (Public Access Buildings), the use of flame is even prohibited.
Applicators, meanwhile, are vulnerable to serious burns and the inhalation of toxic fumes (aromatic hydrocarbons, VOCs), which are harmful to their long-term health.
And let’s not forget the environmental impact : burning bitumen emits CO₂ and fine particles, worsening air pollution. Each square meter treated with flame generates about 150 grams of CO₂, not to mention emissions related to the transport and combustion of propane.
Drylast CRWP® : a flame-free, safe, and high-performance technology
In response to these challenges, our Drylast CRWP® Liquid Waterproofing System was designed for flame-free application. Its cold installation eliminates any risk of fire or burns, protecting both workers and buildings.
Toxic fumes and VOC emissions are eliminated, preserving the health of the teams and the environment.
Our liquid waterproofing technology is particularly effective on sensitive points: equipment bases, waterproofing upstands, skylights... Its liquid texture allows it to perfectly adapt to shapes, reducing risks associated with joints or seams.
Choosing a flame-free solution means opting for greater safety and environmental responsibility !
