Clay soil here that expands and contracts a lot when it is dry/wet/frozen etc. Cracks 1.5" wide when dry.
Have about a 250' long x 50' wide low drainage spot that I need to cross with loaded super b's to access future grain bins on the other side.
Thinking to dig it down 14" and lay down geotextile cloth and fill the 14" back up with pit run for 10" or so and top it off with 1.5" road crush. Idea is to keep the area as the low spot and allow the water to flow across it, but have it solid enough underneath for the trucks to cross. I will only have to use it when wet once in a while, normally it will be dry or frozen. Only looking to gravel 2 spots to cross the low area about 40'x50' each.
Think it will work? Gravel is very expensive here and 80+km one way to haul it. But not sure that 14" is thick enough, though the geotextile should help some.
Also what do you think the conversion is from loose yards of gravel at the pit or tonnes of gravel to packed gravel once placed? I am thinking that it will shrink 1/3 from loose yards to packed yards or is that too high?
There is no way to divert the water around this low spot and a culvert is possible if small, but would have to be 300' long which also gets expensive.
Any other ideas are welcome.
