Basement is a part of a building whose ceilings are located on or below ground level. Cellars usually serve as storage rooms, utility rooms, technical rooms or garages. They are also often used to store food products, wine or other drinks due to naturally lower temperature and constant humidity. In construction, various technologies are used to build cellars, and the materials used are most often concrete, brick or stone. Basements should be adequately insulated and protected against moisture and groundwater to ensure the durability of the building and comfort of use.
