Flexible dams

Flexible portable dams

Portable flood barrier

The flexible Exflooder dam allows you to quickly and efficiently create a mobile flood embankment. It is an effective and efficient alternative to traditional sandbags. After folding, it takes up little space, which makes it easier to store and transport. The Exflooder is made of a three-layer PVC fabric, which provides the necessary resistance to mechanical micro-damage and allows it to adapt to the unevenness of the ground.

  • Filling the dam with water: through the inlet-outlet connection. In smaller dams, the connection is threaded with a plug, you need to obtain the couplings yourself according to the applicable standards. Dams of larger diameters are equipped with a fireman’s cap and a cover.
  • Emptying the dam: through the inlet-outlet connection or, in the case of larger diameters, through an additional drain sleeve.
  • Connecting the barriers: done “overlapping” or using an additional sleeve, if the model is equipped with it. Another barrier is placed in the sleeve of the dam, which, after filling, fills the sleeve with its volume and builds a tight connection.

Advantages of the “Exflooder” mobile flood barrier

Mobility Mobility: Thanks to flexibility and ultimately small footprint, large numbers of dams can be transported quickly and efficiently to the location requiring intervention.
Easy to store Easy to store: When folded, Exflooders occupy a few percent of their target volume, so relatively little space is required for storage.
Practical joining Practical joining: Another barrier is placed in the sleeve, which, after filling, fills the sleeve with its volume and creates a tight connection (option in the model with sleeve). Other types of connection on request.
UV: The PVC fabric is protected with a special varnish, which extends its life during exposure to UV radiation.
HF technology HF technology: The use of high frequency welding (HF) ensures a permanent connection of fabrics in key areas of the product.
Made in Poland Made in Poland: We are a Polish company and the dams are manufactured by us in Gdynia
Durable fabric Durable fabric: A special technical fabric with polyester mesh and PVC compound coating provides the necessary strength.
