How to washing tonnes of muddy gravel?
A relative has about 80mē of gravelled areas around their house. Over
the years, the gravel has become very muddy, and is now coverered with
weeds.
Is there a cost effective way of washing gravel? I've tried putting it
in a handheld steel sieve sloshing it around in wheelbarrow of water,
but that was very slow, and generated large quantities of muddy water.
I suppose I could just put a membrane on top of it, followed by more
gravel, but I'd like to re-use the existing stuff.
