DEWATERING, DIVERSION AND DAMMING
Based on the NoFloods technology we have designed a mobile cofferdam. The NoFloods Cofferdam offers an effective and cost-efficient solution for water control (dewatering, water diversion, damming) in order to facilitate bridge repair, ease the works of excavations, installations, building or simply cleaning out.
The NoFloods Cofferdam is easy to install and is totally safe.The NoFloods cofferdam use on-site water to fill the tube structure, which will cause the dam to slowly and evenly inflate, forming a strong, stable barrier. The NoFloods Cofferdam offer:
EASY INSTALLATION: The NoFloods cofferdam is deployed directly into the water, to set up an ultra fast cofferdam. As the tubes continue to fill and the water pressure builds, the dam is installed in a controlled manner to create the cofferdam. Depending on the size of the cofferdam one or two person can transport and install it easily.
MULTIPLE APPLICATIONS: As the NoFloods Cofferdam can be set up in virtually any stream and since it can be curved in almost any direction, it allows for multiple applications, for instance to dry up one side only of a river/a bridge pillar while leaving the other free for the river flow.
STABILITY: Option to attach a membrane to enhance further stability. This avoids any danger of skidding of the dam.
MODULARITY: it is possible to connect together several sections to create the exact dam-length needed.
Based on the materials used, the NoFloods Cofferdam can remain installed for longer periods of time. The materials have high durability and can withstand tough conditions. The Cofferdam conforms to the terrain and are hence suitable for all common substrates, such as grass, gravel and asphalt. The cofferdam is designed to stop and withstand both still and rushing water and can be installed directly in the water.
