What device is used to hold foundation wall forms together?

The use of snap ties in holding foundation wall forms together is crucial due to their design and functionality. These devices consist of metal rods that go through the forms and secure them tightly during the pouring of concrete. Snap ties allow for the forms to be held in place under the immense pressure of the wet concrete, ensuring that the forms maintain their shape and alignment while the concrete cures.

Additionally, they are specifically designed to be removed after the concrete has set, leaving a clean, smooth surface in the foundation wall without the need for large holes, unlike other options such as nails or screws, which may leave residual material in the concrete. Brackets, while potentially useful in some structural applications, are not typically employed for securing foundation wall forms in the same effective manner as snap ties. This makes snap ties the preferred choice for builders when constructing foundation walls.
