Use some of the same technology used in building bridges, tall buildings, water towers, and other structures that require high strength due to high stresses.  Your swimming pool holds thousands of gallons of water while holding back thousands of pounds of earth. In order to ensure structural integrity over many years it’s important that your pool walls will remain intact regardless of external forces.  With the Fox X-Brace technology you get just that.  Patented by Fox, the X-Brace structure provides 100% support for your pool walls without concern for internal or external pressures.
