By basement we mean one or more levels of a building that are fully or partially below ground level. The construction of basement walls is usually made of reinforced concrete and due to slipshod or other parameters relating to the concrete itself or the times and quality of its application, sources of water inflow are often created. Problems such as deterioration of the concrete and carbonation with oxidation of the reinforcement, due to the creation of cracks and water flow both from the concrete itself and from the perimeter of the plumbing pipes. Also, in several areas with high water table, where the water level exceeds the basement floor level, serious water inflow problems are created.
For this reason, basements are considered among the most vulnerable, as storm water flow is possible from side walls, from the horizontal surface or a combination of these.
In addition to construction failures, the atmospheric conditions in the basement space in question, whether it is a commercial space or the home itself, also play an important role.
For the final solution of the aforementioned as well as the different and separate conditions of basements, a study based on an autopsy of the area must be done first, and moisture measurement with specialized tools as well as the application of cement-based sealing materials and penetrating concrete to develop crystals, in order to provide the best possible solution for effective waterproofing.
