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.
But if you do not install vents, you must insulate the side walls of the crawl space and the heating contractor must pipe in a small amount of conditioned air into the space. Furthermore, the foundation insulation must be fireproof or if it is not, it must be covered with a fireproof material.
