Bentomat
 

We are waiting for our pond to be excavated (two months later than we
hoped), and have been looking at various types of liner. In our water
gardens book it mentions using a material called Bentomat, which
sounds much nicer than butyl. Has anyone any experience of this? Is
it easy to use? And is it wildly more expensive than butyl?

Although I've Googled, Asked Jeeves, and Alta Vistad g I cannot find
a supplier or a price. Can anyone recommend a supplier?

Thanks all for any pointers.

It seems to be used mainly in large scale projects by civil engineering
firms. This lot make it, and may be able to help you:

Looking at the project it's used on, I would say you'd have to be building a
major size pond with shallow sloping sides, and edges. The great advantage
of butyl is it's easy to form into odd sized ponds and the 1mm is extremely
tough.

Bentonite is a type of clay mineral (aka Fullers Earth, aka cat
litter) that is often used for 'puddling' large structures such as
reservoirs and waste tip sites to make them watertight. There used to
be extensive deposits around Redhills in Surrey, but now all worked
out IIRC. Laporte Industries were a major producer. I suspect Bentomat
is a trade name for a bentonite or something similar used for this
type of application.

It's a clay sandwich.
Whilst you don't mention the type of pond you want I would say stick to
Butyl, it's easy to deal with, lasts 50 years + (used for canals!), and is
not easy to puncture and if you do it can be mended just like an inner tube
on a bike. It's also black which is an ideal colour for a liner in a pond.

and they can even weld it to shape so no creases. (If it's a squareish pond)
