The Easy Way to Build a Stone Column
This technical illustration provides a step-by-step guide for constructing a decorative stone column for driveway entrances or fence posts. The method relies on using a concrete block (CMU) core as a structural guide, which is then veneered with natural rubble stone. By building around a rigid, plumb center, the illustrator demonstrates how to achieve professional masonry results with increased stability and simplified alignment.
Key Components
Foundation: A 24-inch deep excavation into virgin soil, stabilized by a 2×4 timber frame and a concrete pour to create a solid footing.
Structural Core: Stacked cinder or concrete blocks laid perpendicularly to reach the desired height, serving as the "spine" of the column.
Alignment Jig: A plywood top square supported by a frame, used to drop a plumb bob and run string lines to ensure the stone veneer remains perfectly vertical and symmetrical.
Stone Veneer: Natural rubble stone laid in mortar around the block core, moving from the outside inward.
Capstone: A flat, finished stone top that provides a clean aesthetic and protects the internal masonry from water infiltration.
Design Summary
The system illustrated prioritizes precision through the use of traditional leveling tools and a secondary internal structure. By using a concrete block core, the builder ensures the column has a high load-bearing capacity and a consistent shape. The addition of the "string line" method from a temporary overhead frame allows even an amateur mason to maintain a uniform thickness and straight edges while working with irregularly shaped natural stones.
