Innovative waterproofing for your roofs
This coating, made of either rubber or modified bitumen, consolidates the roof’s strength and extends its lifespan. This revolutionary technique involves placing a liquid membrane on the roof. When this hardens, a seamless waterproof barrier is formed.
Unlike conventional roofing methods, liquid roofs are incredibly flexible. They adapt to structural movements and weather variations. This characteristic makes them a perfect option for regions subject to significant temperature variations.
What’s more, this alternative offers maximum protection for your roof, extending its durability and enhancing the aesthetic value of your property. If you’re looking for an environmentally-friendly membrane, the liquid version is an optimal choice, preventing heat build-up. This ensures optimum energy-efficient performance while minimizing heating and cooling costs.
Cost-effective, long-term solution
Liquid roofing is a cost-effective option, especially if you’re renovating an existing roof. Complete replacement is not inevitable. Installing a liquid membrane directly over the existing structure offers a cost-effective alternative, reducing material and labor costs. What’s more, thanks to their low maintenance and long service life, liquid roofing is an attractive long-term investment.
Liquid roofs are also part of an ecological approach. By maximizing the lifespan of existing roofs, they help reduce construction waste. What’s more, the products used are generally formulated to be environmentally friendly, with no harmful solvents or VOCs (volatile organic compounds). This makes them a responsible option for those wishing to limit their ecological footprint.
Liquid roofing is a robust alternative for optimal waterproofing of roofs, with undeniable advantages in terms of flexibility, longevity and cost-effectiveness. However, for maximum efficiency and durability, it’s essential to call on experts who can select the right product and install it in compliance with technical requirements. Whether for new buildings or renovations, liquid roofing is an increasingly popular alternative for extreme climates.

Advantages of liquid membranes
Liquid membranes are distinguished by their ability to create a uniform, seamless cover. This means there are no areas susceptible to water infiltration. The system is suitable for flat or slightly sloping roofs with a tendency to water stagnation. Thanks to this seamless membrane, the roof becomes completely watertight, preserving the building’s structure and reducing long-term repair and maintenance costs.
The materials used for liquid roofing are polymers or elastomers in liquid form, which dry to form a solid yet flexible coating. They have been specially developed to offer enhanced resistance to ultraviolet rays, extreme weather conditions and temperature variations. Their unique elasticity enables them to adapt to the natural movements of the building, reducing the risk of cracking or tearing and ensuring exceptional durability.
Roof renovation with liquid membrane
Metal roofing
Metal roofs, distinguished by their durability, are prone to waterproofing problems. This can be due to rust or water infiltration. Opting for a liquid membrane to be installed directly over the old metal cladding proves effective. This continuous, seamless layer protects the structure from leaks.
This membrane is ideal for renovation projects. It prolongs the life of your roof while guaranteeing reinforced waterproofing. It is generally applied by spraying, a process requiring the intervention of professionals equipped with the appropriate tools for impeccable results.
Elastomeric coatings and innovative roofing solutions
Elastomer coating is distinguished by its superior quality and outstanding durability, making it an ideal choice for long-lasting, hard-wearing roofs. Although its initial cost is generally higher, it proves to be a sound investment over the long term.
For those wishing to modernize a roof with an elastomeric coating, the liquid membrane emerges as an effective solution. Laid directly onto the existing surface, this covering offers optimum waterproofing or can be used to treat only defective areas, depending on the overall condition of the roof.
Applying a liquid membrane to a flat roof: a mastered process
One of the main advantages of liquid membranes is their ability to be applied to complex shapes and structures, including areas around stacks, vents and other entry points, where conventional coatings might encounter difficulties.
Once cured, this membrane requires little maintenance. However, periodic inspections are recommended to verify its integrity. In the event of deterioration, the coating can be quickly and easily repaired by adding a fresh layer of liquid roofing.
The roof must be thoroughly cleaned to remove any dirt, twigs or mould. Breaches and other damage must be repaired before applying the membrane, ensuring a homogeneous surface ready for treatment.
Vulnerable areas, such as joints and fasteners, are first primed. This is essential to ensure optimum waterproofing while enhancing the adhesion of subsequent protective coats.
The liquid coating is then applied in several coats, adapted to the requirements of the material. This operation can be carried out using a roller, brush or spray system, depending on the specific needs of the site, to ensure optimum rendering.
Once the coating has been laid, it’s important to give it time to dry, a process that can vary depending on the climate. It is advisable to avoid all traffic on the surface to preserve the integrity of the membrane.
When the membrane is completely dry, a thorough inspection is carried out to identify any imperfections or poorly covered gaps. If necessary, touch-ups are carried out to ensure a complete and optimal seal.
By following this methodology, the liquid membrane provides effective, long-lasting protection against water infiltration, offering a reliable, long-lasting roofing solution, even in harsh climatic conditions.
