EPDM membranes
Our EPDM membranes meet the most demanding criteria: durability, potability. The implementation is simple and requires no special tools.
EPDM roofing sheets are available in 2 thicknesses: 1.20 mm and 1.52 mm. The 1.52 mm thickness is recommended when ballasting the roof with greenery, gravel or slabs on studs. The 1.52 mm thick EPDM tarpaulin facilitates glued installation because it is less flexible.
EPDM tarpaulins are sold by the cut or by the roll.

1.20mm or 1.52mm? What thickness of EPDM membrane should I choose?
The economical solution: the EPDM membrane in thickness 1.20 mm
The 1.20 mm thick EPDM cover is the minimum thickness for an EPDM roof. It is the reliability of the EPDM material, ensuring the tightness, at the lowest cost. The implementation is simple and requires very few tools. The material's longevity of more than 40 years is far superior to all the other materials offered for sealing a flat roof. The EPDM membrane respects the environment because rainwater is not polluted, it is part of the sustainable development approach.
The advantages of the EPDM membrane in thickness 1.52 mm
The 1.52 mm thick EPDM membrane has several advantages
The gain in solidity is particularly recommended for EPDM membranes on which there will be ballast: vegetation, slabs on studs, rolled gravel, etc. But this gain in solidity does not exempt it from the anti-punching geotextile essential for any type of ballasting of the membrane.
The implementation is even easier because the 1.52 mm EPDM membrane bends less easily when bonding to the support, when unrolling the membrane.
How do I properly take the ribs of my construction site?
The EPDM membrane must cover the running surface, the ramp and the top of the parapets. In the case of an adjoining wall, the membrane must rise a minimum of 15 cm on the wall.
If the dimensions of your roof allow it, the membrane will be in one piece and there will be no joint between the lengths to be made. However, making a joint between strips is not difficult, our installation instructions supplied with all orders detail each operation precisely. A joint between strips requires an overlap zone of at least 10 to 12 cm, ie the 2 strips overlap over a width of at least 10 to 12 cm. If there are one or more parapets in the central part of the roof, then the joints between the lengths will preferably be made on top of the parapets.
The necessary dimensions are therefore the length and width of the current part, inside the parapets, the maximum height of the parapets, and the width of the parapets.

What is the advantage of EPDM over bitumen or bituminous coating?
The simplicity of the installation
Unlike bitumen, whose many strips need to be welded with a torch, the EPDM membrane is much simpler to install and without the risk of fire or burns.
The many strips of bitumen and therefore the many joints between strips multiply the risks of leaks and infiltration whereas the EPDM membrane is often laid in one piece and the membrane is cut in the corners of the building only at the level of the top of the parapets.
The ecological advantage
The EPDM membrane offers an excellent ecological balance since it does not contain heavy metals, chlorine or hydrocarbons. Fully recyclable, this material has a limited environmental impact. The EPDM membrane does not pollute rainwater, so it is suitable for receiving revegetation and recovery systems.
The economic advantage
Although a little more expensive to buy, the EPDM membrane makes a huge difference in the long run. The lifespan of an EPDM membrane is over 40 years while bitumen is on average 10 years. So to really compare the costs, you have to multiply the cost of the bitumen by 4.
What substrates are compatible with EPDM sealing?
The advantage of the EPDM membrane is that it can be used on most supports:
- wood,
- concrete,
- chipboard,
- PIR EPDM insulation,
- steel sheets,
- under renovation on bitumen coating.
