When clay soil presses against a block foundation wall, it causes the individual blocks to slide out of alignment. Over time, this makes the wall less stable and can make the home unsafe. The homeowners in this situation realized that they could not sell their home in the current condition, so they opted to repair the home before placing it on the market. The foundation repair that they opted for is called a Wall Anchor Installation and it carried nationally backed warranties that are transferrable to the new owner.
