Use Water Against Water

Tentdam is a water-filled mobile flood protection system.

With a length of 100 meters and a height of 1.8 meters, Tentdam requires a team of two, two hours and no specialized knowledge or tools to set up. It can be installed on any terrain and surface. It is easy to clean after use. Storage and transportation require very little space, maintenance is extremely economical.

Environment-friendly and pollution-free, Tentdam requires no landscaping whatsoever.


Tentdam has two main characteristics from an end-user perspective.

The first is mobility, the second is lightness.

Using Tentdam, a temporary dam can be built anywhere. It is affordable for individual buyers, and a small trailer or semitrailer is enough to carry it.

It requires small storage space and virtually no maintenance.

Only a few people are required for the assembly of the system.

For example, a restaurant on a waterfront, a hotel with its own staff

a housing arrangement or a set of companies in industrial areas can collectively protect their homes and assets in case of a potential flood.

Innovation and Patent

Water-filled dams have proven to be the best among known temporary mobile barrier types. Tentdam brings a selection of revolutionary innovations to this area. For instance, the familiar circular shape was changed to a triangular one, providing the system with maximum resistance against skewing and sliding off. Tentdam uses a completely new way of joining parts thus enabling faster installation while also making the system much more leak-proof than previous systems.

Tentdam flood protection system can be used to create temporary liquid storage areas.
