Small cracks in foundation walls are common in homes throughout the Maine and New Hampshire 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 TC Hafford Basement Systems, 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 an appropriate wall vapor barrier on basement walls before finishing!
Unlike hydraulic cements and some epoxies, the special sealant used for FlexiSpan® will never dry out or re-crack over 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 and the crack will releak.
FlexiSpan® stays bonded with wall movement, and seals the crack permanently, no matter what.
