In fact, most people with diverticulosis do not have symptoms. However, diverticulosis can sometimes cause unexplained painful cramps, bowel movement disturbances, and blood in the stool. The narrow opening of a diverticulum can bleed, sometimes heavily, into the intestine and out through the rectum.
Our first step in waterproofing your crawl space is to create a perimeter drainage channel along the interior edge of your foundation walls. Any water entering from your floor (or through the walls themselves) is collected in this drainage system, which is pitched downwards to a sump pump.
Calculate the cubic area of the crawl space by multiplying the length x width x height (in feet). Divide this number by 15 to determine the minimum CFM required to fully ventilate the space in 15 minutes. For example, this two-fan crawl space ventilator delivers 220 CFM and will ventilate a 3,600 cubic foot area in 15 minutes.
