I am living in a basement apartment and the outside wall that is “under ground” need to be waterproofed but the dirt must be digged out to open up the cement wall. The terrain is unsuitable to bring digging machines in. 2 to 3 men should easily dig the dirt out in one day. The soil can stay on site. Once the walls are exposed I will lance the next project to do the waterproofing for me. Thank you
