What is a tie rod hole and how did it get there?

When a foundation contractor erects the form of your basement, tie rods are fastened to support the shuttering (walls) which holds the weight and the form of the foundation wall. Once the cement is poured, these forms are left a few days for curing. Next, the tie rods are removed allowing the forms to be dismantled and your foundation is complete. The walls now have holes where the tie rods were that are approximately 5/8 inches in diameter, usually in two rows separated every 18 inches throughout the entire basement. In this type of conventional forming system, the tie rods are not left in the wall. The only time supporting wall forming ties are left in the wall is when a contractor uses a wall forming system that utilizes snap ties.
