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.
I have recently had to examine my foundations for the same reason. I excavated a test hole and exposed the exsisting concrete foundation. Then simply measured the thickness and width of it. Which was 600mm wide by 250mm deep. Which is pretty standard thickness to take a two story house in the UK. * the depth the concrete is at depends on the ground in your area.
