Are play clay blocks frostproof?

[Idus]

I am working on delineating/securing against digging through some gravel in our chicken yard, and the simplest solution is to do this with leca blocks... BUT it is partially below ground level, and water often collects there as it is a natural depression.

Can leca blocks withstand being in water that freezes and thaws during the winter, or will they deteriorate? I prefer a long-lasting solution that may be difficult to redo as we are planning to build nearby as well.

The alternative is to buy retaining wall blocks, which would mean a completely different budget (which is already strained).

Grateful for feedback or alternatives

Well, they are completely frost-resistant if water can drain away from them. But if they turn into ice blocks, there's probably a risk that pieces might break off.

Used concrete garden tiles are usually free and are reasonably frost-resistant and should be suitable for the purpose.

Yes, it would be great to get hold of those. I need to build a "wall" of about 1.5 square meters (from the side) - so it will take quite a bit. Thanks for the tip - I will look for it online.

Well, they are completely frost resistant if water can drain away from them. But if they become like ice cubes, there's a chance chunks might break off.

Well, sometimes they might "stand" in water and risk freezing. :-/ I might consider a combo instead with concrete blocks (or old concrete slabs) for the part exposed to water and maybe lakeblock on top.
