How to Finish Top of Retaining Wall
I'm just completing a dry-stacked retaining wall. Between the stones and the soil, I've packed in about 3-6 inch width of small stones and gravel. Between this and the soil is landscape fabric. I did not go as high as the soil grade, in some stretches, and plan to slope the soil to meet the top of the stones. I'm wondering whether to bring the soil over the gravel backfill area, perhaps cover the gravel first with more landscape fabric or ? I'm not planning to go any higher, also, I realize that ideally I would have large capping stones to finish it off, but I've none left.
I've noted in the neighbourhood that sometimes people use mortar to create a smooth top layer. It looks tidy but you don't get to see the nice top face of the rock. I have not used mortar in the wall itself. Your thoughts are appreciated.
