The present invention 10 discloses a device to aid in providing ballast to place an object, e.g., a tank 16, underground. The device comprises a pair of generally horizontal elongated cylindrical members 30 having a bell 58 and spigot 60 type end for being joined together. A pair of upstanding cylindrical members 26 are provided on the horizontal cylindrical member 30 for connection to a source of pumpable concrete 48. Concrete 48 is pumped into one upright member 26 and air 50 is allowed to pass out the other upright member. Means 36 are provided for closing the ends of the horizontal member 30 so that concrete 48 will not leak out, with the means 36 using rebars 34 and, e.g., steel tek 52. Means 41 are also provided to the cylindrical members for attaching coupling cables 42 thereto so that the object, e.g., tank 16, can be properly ballasted.
