Abstract: A building is reinforced by bonding a foundation slab to piles driven into the earth. Each pile has a cap attached to it at a height selected so that at least a portion of the cap can be captured within the foundation slab when it is poured. Before pouring, reinforcing cables are connected horizontally between selected attachment points on the pile caps and are set to a selected tension. Roof reinforcing cables may also be run from a pile cap upwardly through a wall, generally horizontally so as to capture roofing members, and down through another wall to be attached to a second pile cap.
