Optimization of Compaction Grouting in Collapsible Soils
Six multi-family residential buildings consisting of wood frame structures founded on post-tensioned slabs-on-grade were constructed in approximately 1995 in Basalt, Colorado. Collapsible soils had been identified at the site, in geohazard evaluations, as early as 1976 and a pre-construction geotechnical investigation indicated that the silty clay soils at shallow foundation depths could have high collapse potential when wetted. The buildings experienced between 4.8 and 13.0 cm (1.9 and 5.1 in.) of differential settlement between 1995 and December 2006. Compaction grouting test pads were constructed and pre- and post-grouting analyses of the soils were conducted to quantify changes in moisture content, density, compressive strength, and collapse potential of the soils. Introduction of water into the soils prior to grouting played a significant role in the improvement of soil conditions under the buildings. The grouting methodologies are summarized, and the resulting soil improvement at the test pads and stabilized buildings is discussed.
