Initially I was looking for this:
I was told that distributors do not sell this anymore because it is unsafe (tripping hazard). I am thinking about using the joint between my pavers and my edge to for a drain channel. The patio is sloped in such a way that it will allow me to do this. Here is a ground zero view of my patio and the beveled concrete blocks used for edging.
Do I need to supplementary seal the joint between pavers and patio edge concrete blocks when that joint is used as a drain channel?
