SKU: N/A Category:


Water-Gate flexible cofferdams are used by contractors and site managers for their efficiency, simplicity and versatility.

Use to create areas to repair structures, underpinning, reinforce river supports, repointing, restoring ecological continuity, removing log jams, renovating bank, draining feeder canals, etc.

Works in water – rivers – canals – ponds. WA Water-Gates can be used in a variety of situations. Uneven ground increases friction and thus the stability of the dam. Care is required when using the dam on muddy ground. On a concrete surface, we recommend using the WL range of flexible cofferdams, rather than the WA range of cofferdams. On a sandy surface, you must bury the leading edge to limits the effects of piping erosion.


In Water-Works

The Water-Gate is a temporary water barrier which is unique in the way that, once rolled out, it self-deploys.

It uses the weight of the water to hold the water back. The water lifts the top of the barrier whilst at the same time weighing the base down, forming a seal. By utilising this unique self-opening method, it reduces the time, effort and number of people required to install it.


There are a range of sizes available to suit different applications.
