Veneer Anchoring and Stitching
URM structures may have missing or inadequate ties between masonry veneer wythes and/or between the veneer and the back-up material. As an alternative to drilled adhesive dowels, Simpson Strong-Tie’s Heli-Tie serves as a cost effective retrofit veneer tie. The Heli-Tie is a stainless steel helical tie that is easily installed into a pre-drilled hole. During the installation process the stitching ties are countersunk into the veneer face by way of the installation tool making for an aesthetically pleasing appearance. The Simpson Strong-Tie Heli-Tie helical stitching tie provides a unique solution to the preservation and repair of damaged brick and masonry structures. Stitching ties are grouted into existing masonry joints to repair cracks and increase strength with minimum disturbance.
