Once the debris has been removed from the demolition of the previous home we can dig the basement and prepare for the foundation. The excavator first determines where the land engineer's “benchmark” or zero point of the elevation is located. The excavator determines from the benchmark how deep to dig and places wooden stakes at the corners of the proposed structure. He will use a large backhoe, digging the rear first while gradually backing out of the property.
To form the concrete basement floors and walls and install the exterior drain tile, the basement hole will be dug approximately 36" wider and deeper than the proposed home. The dirt from the dig, will be piled near the front of the property, and later loaded into a dump truck with either a backhoe or bucket loader to be hauled away.
