Slab leaks are similar to hidden water pipe leaks. In some cases, you won’t know you have this problem until significant damage has already occurred. Slab leaks occur when the cement in your foundation starts to crack, bubble, or bend. The two main causes are water line leaks and sewer line leaks.
Old, corroded pipes are often prone to developing leaks. When a water line leak occurs under your home’s foundation, you have a slab leak. If not addressed in time, the leak can cause the soil surrounding the water line to shift away from the slab foundation resulting in structural damage.
