Will the Water Force withstand parallel water ow?

Parallel water ow is not a problem. In the photo, there was more water

owing than the Water Force intended to withstand, and the current was

swift. In the same trail with lots of parallel owing water, we attempted to

damage the Water Force with wood fragments. Our testing process was

rigorous but did not result in any damage to the Water Force.

What about leaks from the Water Force system?

All ood control systems have some type of seepage. You should expect the

Water Force to have seepage.

Seepage rates can vary & improve as more water arrives. Example:

Barrier with 4in (10cm) of water = seepage of 1 Gal/min/linear foot.

Same Barrier with 20in (50cm) of water= seepage of 1/2 Gal/min/linear foot.

If the water barrier is laid down on a regular asphalt surface, with 4in (10 cm) of

retained water, the size of the leaks can be around 1 Gal/min/linear 3ft. However, if the barrier retains 20in

(50cm) of water, only about 1/2 Gal/min/ 3ft will leak from it.

Your emergency plan should denitely include pumps to remove any water leaking through the Water Force

as well as from rain, down spouts, drainage back ows & anything else that may put water in unwanted

places. We recommend using gas powered water pumps that do not depend on electrical power and plan

for leaks that may be greater than the amount of water expected to ow under or appear around the barrier.

Will the Water Force barrier withstand freeze-thaw cycles?

Our PVC fabric manufacturer warrants its products against cracking at a

temperature of -22º F (-30º C), and the polyethylene partitions are

guaranteed to withstand temperatures as low as -40º F/C.

The PVC fabric and polyethylene used to make our barriers are the same

as those used for road transport and car shelters. They are very resistant

to extreme temperatures and have proven their worth over several

decades of freeze-thaw cycles.

The water barrier in the photograph was placed in a stream at a temperature

of -4º F (-20º C) for a period of three days. A layer of ice formed on the inside, at the top of the PVC (yellow)

fabric, but was very easy to remove by just tapping the barrier. The ice came unstuck, immediately oated

to the top of the barrier, slid over it and ended up behind it.
