Heading: The Fuller and Rupiper Method

Text: 7 The Fuller and Rupiper method uses screw anchors with concrete haunches as an underpinning solution. In this method, popular in settings having high seismic activity such as California, the user excavates the earth around and beneath the foundation to install a screw anchor and to place steel reinforcing rods in the excavation. The contractor then pours concrete into the excavation and allows the concrete to dry before backfilling the excavation. In the concrete haunch method, the weight of the structure is not transferred to the screw anchor until there is further downward settlement of the foundation onto the hardened concrete. This method must also be performed in a specific sequence, as the screw anchor must be installed before the concrete hardens, and the resulting connection is formed. 8
