Controlling soil slippage on a steep backyard hill became an urgent priority after spring storms caused minor mudslides near our patio. To find a durable engineering solution that could handle heavy ground movement, I reviewed various structural designs featured on https://oakshs.ca/retaining-walls/ for inspiration. Different soil types and slope angles dictate whether you need gravity walls, geogrid reinforcement, or tiered terracing to maintain long-term stability. Installing adequate weep holes and drainage gravel behind the blocks ensures that trapped rainwater never builds up dangerous hydrostatic pressure. Our hillside is now completely secured, and the multi-tiered garden layout looks absolutely stunning.
