Waterproofing Products forUNDERGROUND STRUCTURES

Underground structures level: the parts of a building which are most often incontact with water and aggressive elements in the ground.All structures below ground level come into contact with the humidity in theground or with the water table and must be protected to guarantee the life-span ofbuildings. If no suitable protection is applied, there are no construction materialswith the capacity of resisting the various factors which are present below groundlevel. MAPEI offers a wide array of repair and protection solutions which guaranteean efficient solution for any construction element.01
