Dean and Derek, hosts of DIY's Rock Solid, love stone. But stone just isn't practical for every project--like the eighty-foot retaining wall featured in this project. That would entail a lot of stone, mortar and time. Dean and Derek's solution is to use an interlocking concrete-block system to build a wall that doesn't sacrifice style for substance--and that goes up in a fraction of the time it would take to complete a similar wall with stone. Also part of this project, Dean and Derek replace the existing stairs and a crumbling stone wall with new steps and a retaining wall that tapers from the house down to street level.
