I'm in the middle of building a fence and laying down some chippings. I've dug out ready for a sub base, my plan was to just stick some Mot type 1 down and compact it, then a layer of sand, then gravel grids and back fill. Somebody has now told me that the Mot type 1 may cause drainage issues?? It's only a small area 4.5m X 6.4m (pic attached)
Do I need to consider extra drainage?
The wall underneath the fence on the right is a 4 foot retaining wall
Thanks
