Ever wonder how to attractively balance round objects on top of each other? Dean and Derek have the answer to this age old question in this episode of Rock Solid. Back on home ground in Cohasset, Massachusetts, theyll tackle a garden retaining wall with a mixture of round fieldstones. This garden wall will have a true New England style dry stack look! Dean and Derek select a mixture of stone that will ensure a beautiful finished project, and theyll build the wall with an emphasis on ratio and tight, consistent joints no easy feat when the stones range in size from basketballs to baseballs and have no flat edges! The end result is one that gardeners and backyard aficionados everywhere will be eager to call their own.
