Do you want more space in the basement of your home or maybe you need yard drain boxes, vent wells, foundation drain lines, or a cistern installed. Well keep in mind, the first step in any of these major remodeling projects is excavation. If not done properly can be vary dangerous. One of the most dangerous aspects of excavation is cave in’s. Why do cave in’s occur? Soil that is undisturbed  remains in place because  of the natural pressure forces of the soil around it, as well as the forces if gravity. When you excavate, the soil around the trenched area has no pressure to hold it in place causing a cave in. So if you are planning any project that requires excavation  make sure the company hire is professional and safe.
