A basement wall crack in a poured basement foundation is generally caused by concrete shrinkage. This shrinkage can continue for three years after the basement wall has been initially poured and sometimes can occur even longer afterward. Even after this period, continued pressures, such as soil contraction and expansion, can cause further foundation cracks in southeast Michigan and separation.
