Abstract
One of the problems regularly facing engineers in designing additions to buildings or other structures is dealing with excavating for footings directly adjoining existing footings but at a deeper level. This was accomplished in sandy soils economically and quickly for a noted Conference Center in 1983 by using compaction grouting. Compaction piles were utilized to pick up existing loads as well as the horizontal loads which would normally allow the building to tip, settle and crack. We believe this was the first use of compaction piles as "anchor" piles to pick up horizontal loads. By using this process, the sandy soils along the excavation stood without other support when excavating with a backhoe. The paper presents the criteria used in developing this method, summarizes the critical loads, and explains the operation. There has been no settlement at the site.

Vertical Excavation below Footing Solved by Compaction Grouting
One of the problems regularly facing engineers in designing additions to buildings or other structures is dealing with excavating for footings directly adjoining existing footings but at a deeper level. This was accomplished in sandy soils economically and quickly for a noted Conference Center in 1983 by using compaction grouting. Compaction piles were utilized to pick up existing loads as well as the horizontal loads which would normally allow the building to tip, settle and crack. We believe this was the first use of compaction piles as "anchor" piles to pick up horizontal loads. By using this process, the sandy soils along the excavation stood without other support when excavating with a backhoe. The paper presents the criteria used in developing this method, summarizes the critical loads, and explains the operation. There has been no settlement at the site.
