What is a Snap Tie in Construction?

May. 14, 2021


Concrete Form Snap Ties are basically tension members. They are designed to resist the lateral pressure of fresh concrete on vertical forms.When properly fitted with cones or other they hold the wall forms at the proper distance to create the desired concrete wall thickness. The cones allow the snap tie to be broken off inside the concrete for surface patching.
