Product Description:
A new wall is built to come alongside of an existing, failing foundation wall and provides the necessary reinforcement to do the job that the original wall is no longer capable of. The process typically involves formal engineering design. Most often, sister wall designs call for reinforcing steel in the wall, and require the construction of one-sided concrete wall forms. Once wall steel and forms are in place, concrete is pumped into the forms and allowed to set. The forms may then be removed, and the job stands completed. Sister walls generally do require a building permit and inspections by the building authorities.
