Problem: Tie Rod Dampness
Tie Rods (form ties) are the steel pieces used to hold both sides of the concrete forms together when your home's foundation was initially poured. After the concrete has cured and the forms are taken off the sides, the ends of the tie rods are broken off which leaves part of the steel rod still inside the cured concrete. There is a chance that these can eventually rust over time and leave a hole which water can pass through.
If the tie rods rust, they will create holes in your concrete walls. These holes will make it much easier for water to seep through the walls and into your basement or crawl space. This is a common basement problem, and a lot of homeowners in Denver tend to ignore it because they assume solutions to these issues are very difficult or costly, or they think it's not as big of a problem as it really is.
