I have a quite a bit of concreting to do in a yard and shall probably need to protect the front of a couple of sheds from water ingress. I have found these two different ways of doing this.
I imagine the slotted one is cheaper but maybe prone to blockage of slots?
Any experiences or ideas gratefully received.
