Frequently Asked Questions

How much stone do I need for a wall?
For a fieldstone wall, plan on approximately 1 ton per 8-10 cubic feet of wall volume, accounting for air gaps and irregular shapes. Cut stone is denser at about 150 lbs per cubic foot.
How high can a stone wall be without engineering?
Most building codes allow dry-stacked retaining walls up to 3-4 feet without engineering. Walls over 4 feet typically require engineered plans, proper drainage, and a building permit.
Does a stone retaining wall need drainage?
Yes, proper drainage is critical. Install perforated drain pipe at the base, gravel backfill behind the wall, and weep holes. Poor drainage is the number one cause of retaining wall failure.
