This thing is made of elastomer folded in several layers. Therefore, it is very durable; even specially cutting it is quite problematic. This elastomer is a polymer-impregnated material. Something similar to tarpaulin from which they make canopies for motor transport.

Actually to the issue of strength. Have you seen such a focus?

This thing unfolds very quickly. Dams for MES are supplied in sets. In each set - 4 boxes (4 dams of 25 meters in length). In one of these boxes is a motor pump, sleeves and trunnions.
The dam has inlet valves and drain holes at the bottom. When filling, all inlets are sure to open, so no air bubble is formed inside.
And now memes. All remember this picture here?

So - banter was not the topic. These guys are preparing to fill the very WFD, and a large size. Look here - familiar to us boxes from under the WFD:

Dams can build up in height. Approximately as follows:

It is natural to block the mudflow with such a dam, or the river’s flow is impossible. The main purpose of this design is water disposal.
Actually, let's move on to how it all should look like:
1) Comes 4 boxes (1 set) to divert water from the hospital. Side of the site in the area of ​​80m flooding

2) There are 4 conscript soldiers and sandbags.
3) While the WFD is traveling, the conscripts lay sandbags every 3 meters along the side of the plot.
4) An empty dam 25 meters long from the first box unfolds between the sandbags placed in advance. Removed the intake valve. Like these ones:

5) A motor-pump gets and starts (the PS car chases into place at will).
6) The intake sleeve of the motor-pump rushes straight into the advancing element. Weekend stuck in our dam.

7) The second sleeve at this time unfolds further overlapped to the first.
8) The filling of the sleeve begins. When the first dam reaches the design height, the motor-pump sleeve is connected to the next one.

9) When all 4 sleeves from the dam set are filled, taking into account the overlaps, we get 90 meters of the protected perimeter.
10) Do not forget about the pump? So you still need it to pump out the leaking amount of water from under the dam. Those. Now we place the suction hose in a puddle on the protected side, and throw the drain so that the water goes into the “element”.
11) When the water is gone - open the drain valve and drain the water from the dam. You can do this with the help of the same motor-pump (here is the rescuer then) by connecting the intake hose and the drain valve through the trunnion. Only you need to open the inlet valve on the dam so that air gets into it.
12) We collapse the dam into the box. We transport to the place of a new threat, or we leave it in stock until the next big water.
13) If damage is detected on the dam, they are eliminated with a special hairdryer. This certainly has many advertising agencies that are engaged in billboards, and those who are stretching avtotenty. The material for the patch can be obtained from the manufacturer of the dam.

So, without staining the foliage company with the green color of hard labor of a heap of conscripts and EMERCOM employees, you can secure objects that are in the flooded area.
But, if you think that the WFD is the only thing that is used from such technologies, then you are deeply mistaken.
This is the Russian oil storage in the Yamal Peninsula. The extracted oil is first stored in these “Mobile Elastic Oil-Gas Tanks” (PER-NG). This kind of separators, they allow you to defend the oil before transporting to the tanker, separate the gas, which is immediately used in the boiler room.
