I want to write to say that your product for fixing leaking dams works brilliantly.

I must say I was sceptical about this polymer stuff.

But we now have a dam that is not leaking at all & about to overflow with the rain we’re getting on the Sth Coast of NSW.
It’s great to have bought a product that simply does what it is advertised to do.
