Cracks present in foundations or basement floors are sometimes linked to completely natural phenomena. Concrete is not elastic and undergoes shrinkage which can create small cracks that are often harmless. However, you should never ignore foundation problems, as they can hide more important issues such as structural cracks. It is essential to control their evolution and ensure proper foundation crack repairs when needed to avoid water infiltration problems. These repairs are even more essential if your foundation walls are not protected by an effective waterproofing process.
