What is Snap Tie?
Definition of Snap Tie in Construction
The fasteners that secure two opposing sides of a formwork box, wall or other concrete component requiring a form. The snap tie is designed to be installed at an on center spacing, and is designed to withstand the lateral forces of wet fluid concrete within the formwork. Snap ties come in different lengths dependent upon the application. The snap ties, upon removal of the formwork, can be snapped off and will snap, slightly under the surface of the concrete. This creates a small dimple affect, that can be later filled with masonry, and rubbed down to eliminate the distortion of the concrete surfaces due to the use of the ties. Snap ties make the installation of concrete formwork and the subsequent removal extremely easy and efficient. The forming of a one sided wall requires another type of tie that can either be a snap tie, if so designed, or a custom built tie designed specifically for this one sided application. The use of threaded rod is a common solution for this type of wall tie and together with structurally designed accessories, will function as the structural tie for this type of wall. There are several manufacturers for snap ties and the type of formwork being used will normally influence the type and manufacturer of the snap tie utilized.
