Hi, hoping someone can help. I'm doing the garden landscaping myself and accidently built the retaining wall about 80-100mm too short. Any ideas on adding height but keeping the short edge? I was thinking 3m Brown Fence Posts at 100mmx100mm on top, would that suffice or would I be better adding normal 2.4mm sleepers on the fat side to get the required height? Cheers! Lee
