What is the purpose of using wedges in a patching kit?

The use of wedges in a patching kit primarily serves to hold the patch in place during the repair process. When applying a patch to a damaged area, especially in situations involving leaks or pressure, it is crucial that the patch remains tightly secured to effectively prevent further water or fluid intrusion. Wedges can be inserted around the edges of the patch to create a snug fit, ensuring that it adheres properly and remains stable while additional securing methods (such as tape or adhesive) are applied.

This securing function of the wedges is vital in achieving a successful repair, as any movement or misalignment can compromise the integrity of the patch and potentially result in continued leakage or damage. Thus, the role of wedges is essential in facilitating a robust and effective patching operation by providing the necessary stability and support during the repair.
