Gabion baskets and waterproof membrane for water retention structure

Gabion baskets and waterproof membrane for water retention structure

(OP)
Has anyone used  a dam made from rock filled gabion baskets  with a central water proof membrane  to form a temporary water retaining structure?

RE: Gabion baskets and waterproof membrane for water retention structure

I used gabion baskets as retaining walls; but not as a dam. For retaining structures it very undesirable to retain water behind the wall because it adds up more load to the lateral soil pressure.

Haven't used gabions for a temporary dam but have used precast jersey barriers with a membrane.  You may alos want to check out PortaDam water retaining structures.

Never tried it, but it sounds good to me. - You will need to do something to stop the membrane getting punctured.
How are you thinking of building it? - Front part (downstream) then membrane then rear gabions? If so could you leave the membrane exposed to ease future repairs?

Gabions, with a waterproof coating, are used as the "impervious core of a earth dike". See page 424, in Chapter 13, of "Handbook of Steel Drainage & Highway Construction Products". Here is a link to the free .pdf download

A lot of useful information in this publication.

Well done my friend! Your knack to find references and the speed you do it is very well appreciated by me. I am sure other colleagues appreciate it as well.

You get a star from me.
