  • Precast concrete structural units and burial vaults
    Patent number: 4476657
    Abstract: A precast concrete structural unit is provided including a concrete sub-unit and a plastic resinous sheet. The sheet is adhered to the sub-unit at the time of pouring the concrete, utilizing a polychloroprene contact adhesive. The structural unit may further include adhesive coated reinforcement. Among the concrete structural units which are provided is a burial vault including concrete wall portions and a plastic resinous liner. The liner is adhered to the wall portions, at the time of pouring the concrete, utilizing the polychloroprene contact adhesive. The vault may also include adhesive coated reinforcement. The polychloroprene contact adhesive is essentially a blended aqueous latex comprising hydrophilic chloroprene copolymer latex particles and emulsified or dispersed hydrocarbon resin tackifier particles.

  • Sealant system for burial vault and method of application
    Patent number: 3983206
    Abstract: The disclosed heterogeneous hot-melt sealant system is particularly well suited to sealing the typical tongue-and-groove joint between the base and cover of a burial vault. The hot-melt system comprises a plurality of layers, each layer being a distinct phase which resists chemical or morphological penetration (e.g. paraffin oil migration) from the adjacent layer. The layers are typically applied to the groove in the cover for the vault by individual casting or pouring of each of a plurality of hot-melt compositions in the molten state. Each hot-melt composition comprises an essentially amorphous polypropylene, a hydrocarbon resin (e.g. synthetic terpene resin), and a hydrocarbon (e.g. paraffin) oil. The first (bottom) poured hot-melt contains more polypropylene and less oil and terpene resin than the second (upper) pour.
