We are building a mother-in-law addition to a home in rural Collegedale, Tn. After the layout, dig-out for basement, and gravel foundation we are ready to drop in the precast basement walls. This video shows Superior Walls Co. skillfully install a custom made foundation for this new home. We work closely with local companies like Superior Walls of East Tennessee, Inc and always use the best subcontractors/companies while saving money for our customers.
