Fixing structural foundation problems can be problematic and costly. A structural crack is where the foundation wall feels uneven or the width of the crack is about ¼” or wider. Some structural foundation cracks will require engineer specifications in order to repair. The obvious thing to look for is major crack on the foundation wall. A horizontal crack means that there is a problem. Though all cracks on the basement wall are generally bad, but horizontal cracks are serious. Horizontal cracks occur with the soil [mainly clay] constantly expanding and contracting putting the basement wall under a lot of pressure. Some walls especially block foundation walls tend to bow.
Not all foundation cracks are serious. Some small hairline cracks can occur on drywalls, ceilings, or foundation walls due to minor settlement of the home or seasonal expansion and contraction. If leaking occurs then there is a problem and should be looked at. Newly poured concrete tends to crack as concrete shrinks during the curing process. These cracks are usually surface cracks and those foundation cracks may not go through the entire width of the wall. Majority of common foundation cracks occur around basement windows and doors as it’s a “void” in the foundation wall.
Engineer Report is needed
RCC will follow engineer specifications to repair the structural foundation problem
Once foundation is repaired, waterproofing will take place
If external, once waterproofing materials are applied, soil is to be backfilled and tamped.
