Relevant building openings are protected against the entry of water by constructing steps or flights of stairs with raised platforms and/or raised light wells. The edge of light wells at buildings should be placed 15 to 30 cm above the ground level dependent on the situation of the premises and risk. For basement entrances, additional roofing is recommended.
