  • Precast monument base
    Patent number: 4009547
    Abstract: The invention relates to a precast monument base which is made from precast concrete, and is capable of being installed during any kind of weather conditions. The idea basically involves the utilization of a resilient layer between the base and the base cap to allow proper leveling, and to prevent the entrance of moisture to create problems under freezing conditions. The base extends below the frost line, and hence is not effected by freezing of the ground or excessive amounts of water or moisture.
