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.
When working with cement-based products, always wear eye protection and waterproof gloves. Dig post hole so diameter of the hole is 3 times the width of the post (i.e., the hole for a 4â wood post should be about 12 inches wide). The depth of the hole should be 1/3-1/2 the post height above ground (i.e., a 6-foot tall fence would require a hole depth of at least 2 feet). Step 2. Add about 6 inches of QUIKRETE All-Purpose Gravel into the bottom of the hole. Then compact and level the gravel using a post or 2x4.
