In urban areas, to protect ventilation grids that cannot be sealed. Our solution is to install a portable waterproof chimney made of aluminium or steel, that can be fixed on the floor or the wall, with a top fence opening and a ground peripheral sealant gasket.
Our design is conceived to be efficiently dissembled and manipulated manually without any mechanical assistance (e.g crane). The item can be manufactured to specific local design criteria.
The fixation is on the floor slab with simply removable stainless steel screws, threaded bushes and steel dust cover ( bushes will be cast in the concrete)
The design and manufacture are based on specific requirements allowing mechanical and hydraulic solutions for the water depths, contained between 1 and 3 meters.
- A very low leak rate < 3 liters / hour / sqm
- Quick and easy installation: 5 mn / sim. / stop log
- Entirely removable/movable system
- Alloys with high mechanical resistance
- Suitable for warm or freezing regions (tested below -60°C)
- Maintenance free
- Flood protections are guaranteed for 20 years
We Master the Whole Manufacturing Process
- The entire manufactured protection is in steel or marine aluminium alloys
- We have our own engineering office with experienced staff
- We take into account ground studies to draft in collaboration with the contractor
- The goods are delievered ready-to-be installed, thanks to our millimeter and precise production.
- Thanks to our very long experience, achieved since 1970, we are able to determine and provide the best system of flood protection that is suitable to YOUR requirement!
