been doing more digging and waiting today. I got a glimpse of the underside of next doors garden underneath the canopy of weeds and i can see there are large puddles of water and sodden ground in abundance which answers one of my earlier questions of where the water is coming from. Whenever i disturb a piece of ground underneath the hedge line i get a woosh of pent up water escaping. I dug another hole further up the garden where i said i wasnt seeing a water table. Initially it was empty and dry but after leaving it for several hours it now has about 1 foot of water in it. Think that means im gonna have to dig that trench along the hedgeline to act as a barrier/diversion to the advance of groundwater from next door. Was thinking about a french drain style solution but what do you guys think of covering it up with turf to hide it? Obviously i will grade it properly with different sizes of stone to act as a filter and will put an overflow pipe in it incase it gets really wet in there. I will also line it with permeable landscape fabric to keep it clean whilst allowing the water to enter. Does that sound ok or more like a recipe for disaster, im basing the idea loosely on a premade solution that is like a bag of stones, long and thin like a sausage that you can just pop in the hole and cover up. Before you ask, the remoteness of my location makes any solution require to be diy style and based on manageable chunks of 25kg or less that can be manually handled. If it cant be carried it wont go.
