Do not take by mouth. Clocortolone topical is for use only on the skin. Wash your hands before and after using clocortolone topical, unless you are using the medicine to treat the skin on your hands. Apply a small amount to the affected area and rub it gently into the skin. Do not apply clocortolone topical over a large area of skin.
Your foundation should be at least 18 deep, and be 8 wider than your foundation wall. If you have an 8 foundation, you should have 4 on each side at the footing. So for a 8 foundation, the footing width would be 16.
The first step in building a block wall is pouring a concrete footing for the blocks to rest on. The footing has to be below frost line and as level as you can make it. For a foundation wall with 7 courses (rows) of block, the footing was 30 inches below grade, 24 inches wide and 12 inches deep. Footings require a lot of concrete, so if you're building long walls, it might be a good idea to hire a contractor to pour the footings.
