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.
Examine your crawlspace from both the inside and outside and find all holes and entrances into the space. If your crawlspace is reasonably dark, going inside, turning off the light and looking for sunlight coming in from outside is a great way to do this. Seal the holes with expanding foam or caulk.
