Here's an efficient and highly satisfying method for repairing a hole in a concrete culvert pipe. Begin by pulling a batch of fresh concrete through the pipe using an object that matches the pipe's diameter. This ensures the concrete fills the hole evenly and effectively. For cleaning, a similarly clever technique can be employed: drag an old tire through the pipe using a chain. Attach the chain to a tractor or small excavator, which will then pull the tire through the pipe, dislodging and removing any debris or buildup.
