Snap Tie--the Popular Way to Fasten the Formwork in America Countries
What is 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.
