Interior foundation waterproofing addresses basement internal walls like partitions and equipment room walls. Although not directly contacting soil, they can become damp or moldy due to capillary action, condensation, or slab leaks, affecting indoor environmental quality and equipment safety. This inside foundation waterproofing focuses on preventing moisture migration through walls or structural cracks into interior spaces. Materials are typically chosen for environmental friendliness and ease of application, such as breathable coatings or damp-proof layers. Suitable for basement partitions, storerooms, and utility areas, it enhances comfort and functionality of underground spaces, preventing health risks from dampness.
