Deep vein thrombosis, or deep venous thrombosis, (DVT) is the formation of a blood clot (thrombus) within a deep vein, most commonly the legs. Nonspecific signs may include pain, swelling, redness, warmness, and engorged superficial veins.
Align with the centers of terminal posts. Now, dig the post holes (normally 6 wide and 18 to 24 deep) and set the line posts. Before concrete begins to set, adjust post height by carefully moving post up or down in footing. Top of line posts should be even with string; outside face approximately 1/4 inside.
Calculate the concrete needed for the terminal posts. Each hole for the terminal posts must be 8 inches in diameter and 30 inches deep, requiring 0.85 cubic feet of concrete to fill.. Determine the number of bags of concrete mix needed from the number of cubic feet. A 40-pound bag of concrete mix makes 0.3 cubic feet, 60-pound bags make 0.45 cubic feet and 80-pound bags make 0.6 cubic feet.
