Hi, folks, I came across this site after a Google search on retaining wall structure - and I need your advice…
I need to build a short wall in front of the house, and I wish to make it last for decades. The height will be about 30 inches and the width about 8-10 inches. It will be made out of stones and mortar, and will be at the edge of a small lawn.
I want to lay the first course about 6 inches below grade, but is it necessary to place crushed rock and a drain pipe at the base of the wall under the fill dirt behind it?
I appreciate your opinions and guidance.
