Quick question on French drains

johngalway · 2010-01-26 17:15:38

What's the best type of stone to use, considering the water flow and also cost, and what would be a roundabout figure for a truck load please? Drain would be in peaty soil. ATB, John

In the ideal situation you would have a course garvel surrounding the pipe and covering with a finer gravel on top, but not so fine that it will enter the courser gravel, its all about bridging factors.
But then again it all depends on the level of flow your going to have in the drain and the catchment area.
As regards what a load costs about 10 - 12 yoyo's a load of stone, not sure on the price of pea gravel.
