Hi there,
I've started digging out a pond, aiming for 2m deep x 1.2m wide x 1.2 length - I live in a colder area and am trying to get enough depth for trout to survive winter (will be connected to an aquaponics gardern). I am planning to insert wooden posts, and wooden slats shaped a bit like a box to hold back the soil, and use a pond liner. I have started digging out, and we have clay soil - and I am noticing that water is collecting in the hole.
I am assuming this is happening at the moment because it is the lowest point in the garden, and the water is seeping in from the surrounding wet clay that I can see.
Once there is pond liner and the weight of the pond water in the hole, will this prevent the water from the surrounding soil collecting in the hole? Or do I need to plan for some sort of drainage? Because the hole will be so deep, it won't be easy to get this water to run elsewhere/to a deeper point. But I could try a french drain below, and will probably at least leave a PVC pipe into the cavity so that I can pump water out if there is a disaster....
Also any other suggestions for materials for the retaining wall apart from what is suggested above?
Thanks..
