Related to the word 'glaze', a gley is like a biological plastic membrane such as is found in bogs, which is formed by a bacterial process that requires anaerobic conditions.
Traditionally a technique for sealing ponds and dams, there is potential for the process to be adapted for human-made structures. The Russian-devised version for dams uses a slurry of animal waste (pig manure) applied over the inner base and walls of the dam in multiple, thin layers, which is then itself covered with vegetable organic matter such as grass, leaves, waste paper, cardboard, etc. This is all then given a final layer of soil which is tamped down and the mixture is left for several weeks to allow the (anaerobic) bacteria to complete their task, at which time the dam is ready for flooding.

I think this thread might be about three different things:
1) gley can be the grey color that soil takes when it goes underwater, and the bacteria use up all the oxygen, and then the iron turns into its ferric state, becomes soluble and looses its red color. If you take that grey soil and leave it in oxygen the surface should turn back to a earthy hue.
2) compaction of clay soil can make waterproof layer (pig hoof treatment?)
3) anaerobic decomposition of nitrogen rich organic matter makes water proof slime (mature or green organic layer treatment).

Wow. Fascinating post. Interesting about the puddling of the canals and that sheep were used.
I don't get it. A whale wearing overalls? How does that even work? It's like a tiny ad wearing overalls.
