Project overview
This Bettendorf home had two problems that usually travel together: water getting into the basement, and a north foundation wall that had developed frost-line cracking along with open mortar joints. Frost-line cracks form when freezing soil expands and pushes sideways against the wall.
The crew installed a complete 120-linear-foot interior basement waterproofing system, reinforced the north wall with seven steel I-beams, and tuckpointed the open joints. The whole installation was finished in two days.
Project details
The interior waterproofing system runs the full 120 linear feet of the basement perimeter, collecting water at the base of the walls and the cove joint and carrying it away instead of letting it spread across the floor.
Seven steel I-beams were installed along the north foundation wall and mortared directly against it, so the wall bears on continuous steel rather than on isolated contact points. That gives the wall permanent reinforcement against the lateral soil pressure that caused the cracking.
The open mortar joints along the north wall were tuckpointed to restore the wall’s integrity and close off another path for water.
What homeowners should know
Frost-line cracking, horizontal cracks and deteriorating mortar joints are signs of excessive lateral pressure on a basement wall. Addressing them early is far less expensive than waiting for the wall to move further.
Waterproofing and wall stabilization are often best done together: the same excavation of the floor edge that serves the drain system also exposes the base of the wall, and keeping water away from the foundation reduces the pressure that caused the cracking in the first place.
