For poured concrete foundations, there are instances where a single crack may be the cause of water entering the basement. In these situations, it is sometimes possible to repair just the single crack instead of completing a larger interior or exterior job. Wall crack repairs can be complete from both the interior and exterior of your home in almost the same way that larger repairs are completed.

How does a wall crack repair work?

Internal:

• A trench is broken out along the wall approximately 1.5 ft to 2 ft on either side of the crack, exposing the footing. Extra debris and dirt is removed from in front of the footing and is filled with new gravel creating a dry well or drainage pocket.

• The crack on the wall is chipped out and filled with hydraulic cement.

• An air gap drainage membrane is fastened to the wall.

• Termination bars or end strips are added to the wall on both sides where the membrane ends to keep any potential future water contained.

• New gravel is added on top of the footing up to floor level and the concrete is restored. 

• Due to future foundation shifting, if any water manages to get through the sealed crack, it is directed down below the floor to the dry well where it disperses naturally under the floor itself where gravel is already in black at the time of home construction.

External:

• An excavation of approximately 5 linear feet is completed all the way down to the footing to assess the entire crack area.

• The same process is followed for both exterior waterproofing systems and exterior wall crack repairs to ensure the crack is completely sealed.
