Waterproof chimney

Waterproof Chimney

Function :

In urban areas, some ventilation hatches may not be easily blocked in the advent of a flood. Our solution is to install a portable waterproof chimney made of aluminium, fixed on floor or wall, with a top fence opening and sealed with peripheral sealant gasket.

Design :

Our design is conceived to be easily dissembled and handled manually without mechanical assistance (for ex. Crane). The units can be manufactured to specific local design criteria.

Depending on requirements, stainless steel plugs and screws can be protected from dirt or otherwise.

Performances :

The design and manufacture is based on specific requirements allowing mechanical and hydraulic solutions for water depths of between 1 and 3 meters.
