Drilled Granite Stacks are beautiful pieces of natural stone that have been core drilled and assembled. These drilled granite stack water features resemble a rocky mountain with trickling water pouring down the side to create a sense of calm and tranquillity. Our drilled granite stacks are unique decorative stone towers used as a statement pieces in smaller gardens or as focal pieces and as part of a group in larger designs. Drilled granite stacks have a flat base and can be used on any surface and will elevate any garden design.
