Foundation failure: Your homes foundation structure can become damaged by static pressure on the outside parts of the walls, this is typically caused by poor grading and water drainage. Water that sheds towards a foundation wall can become trapped there and as it is compressed and expanded simultaneously it can easily cause the structures around it to crack and heave. The presence of cracks in your foundation can be more than just a pathway for water and sediment to enter your home, it can potentially become a serious structural concern.
