Ok guys, I need your help. I have about a 1200 square foot house that is on a crawl space and I need to get the dirt under the house up about 8 inches. when it rains, water gets under the house and it molds. So... how would you guys go about getting the sand under the house? I thought about filling buckets up with sand but im not so sure about dragging buckets around under the house. any suggestions?
