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.
If your crawl space isn't ventilated, insulate the walls of the crawl space rather than the subfloor of the room above. This requires less insulation and will eliminate the need to insulate ducts and pipes, separately. You may also want to install a polyurethane vapor barrier over the dirt floor for further protection.
