Place the ground sleeve tube in the center of the hole. While holding the tube on rough vertical, pour concrete around the foundation tube until you have covered approximately 2/3 of the tube. No concrete is allowed to enter the tube. Completely level the foundation tube vertically using the inside or outside wall of the tube. Finish pouring concrete until there is 1/2" to 1" of the tube exposed. Recheck level of tube. Let concrete set for at least 72 hours before erecting flag pole. |
