TIER® Restraint System is a custom-designed, tailor-made restraint ties crafted for the specific purpose of securing stone cladding and coping.

Typically, each stone requires four restraints for secure positioning—two at the top of there stone panel and two at the bottom, usually placed within the horizontal joints. These restraints should be positioned within pre-formed mortises or holes located at the midpoint of the stone panel’s thickness. It’s essential to maintain a minimum distance of 75mm from any stone corner, and the spacing between any two restraints should not exceed 1200mm along the perimeter.
