Browse Forums Landscape & Garden Design 1 Dec 05, 2011 7:36 pm I am building a 600mm high retaining wall with Tasman Blocks. Going by the Selkirk instructions I am digging a 200mm trench, compacting it then filling with 150mm of crushed rock and then compacting that. Because of previous excavation done by the builder part of my trench is already lower than the 200mm I am going to remove. How should I build it up to the correct level? A) Add dirt and compact. B) Add extra crushed rock C) Dig out the rest of trench to the same depth. (don't really want to do that.)
