When water saturates the ground around your foundation, it applies pressure (called hydrostatic pressure) that creates cracks in your concrete. These cracks often start off very thin, as hairline cracks. These cracks may include water intrusion, but not always. But once a crack forms, it creates a weak spot that widens each time the hydrostatic pressure pushes on it. If cracks are left untreated, they expand or multiply.
Your basement can be more useful if it is dry and well ventilated. But in many homes, basements appear neglected since they are wet or humid, and in many cases, smelly due to lack of proper ventilation. Wet or humid basements are not desirable because they promote the growth of mold. Mold has notable harmful effects on both health and different structures in your home. Too much moisture in the basement can also damage your home’s foundation.
