Small cracks in foundation walls are common in homes throughout the Minnesota area. Usually a side effect of the natural curing process of concrete, these cracks usually do not threaten the foundation.
However, even small cracks in a foundation can be a major problem if they leak groundwater into your basement or crawl space.

At Complete Basement Systems of MN, we recommend the FlexiSpan® Foundation Crack Repair System to repair your leaking wall cracks. It's a patented, warrantied repair and a permanent solution. To repair a flooding or leaky wall crack, we follow these five steps:
While leaking wall cracks must be fixed before you finish your basement, your finished basement walls will also need to be protected from water vapor that continually passes through concrete.
Stop this moisture by installing a vapor barrier on basement walls before finishing. Many of our vapor barrier systems double as insulation or as an aesthetic upgrade.
Unlike hydraulic cements and some epoxies, the special polyurethane polymer sealant used for FlexiSpan® will never dry out or recrack due to the natural movement of the foundation wall over long periods of time.
Additionally, hydraulic cements, epoxies, and even urethane injections are not able to bend and stretch along with your foundation movement.
As concrete walls expand and shrink slightly through freeze/thaw and wet/dry cycles, the bonds of these materials will fail, leading to recracking or new cracks forming farther on down the wall. As this occurs, the leaking will begin anew.
The FlexiSpan® System stays bonded with wall movement, and seals the crack permanently -- warrantied! This enables you to count on the basement as dry, usable space, or as space that is ready to be finished into a new living area.
