 9.12.3.1. Placement of Backfill 

This Article requires #backfill to maintain the #structural integrity of the #foundation. If a foundation wall is designed to be laterally supported at the top by the floor system and backfilling is to be carried out before the floor is in place, the wall may fail unless it is temporarily supported. One method for providing temporary support is shown in Figure 9.12.-7.

Care must be taken during backfilling to avoid damaging the drainage tile, the foundation wall, any externally applied thermal insulation, and #dampproofing or #waterproofing membrane.
