Ground Response to Permeation and Compensation Grouting in Stratified Soils
A field trial was conducted to study the feasibility of using a combination of permeation and compensation grouting for mitigating settlements of fragile buildings located in stratified soils consisting of fill, organics, silty sand and glacial deposits of varved silt and clay. Vertical and inclined PVC sleeved port pipes were installed for initial permeation grouting to stabilize the fill and organics below the foundation level. This was followed by pre-conditioning testing using fracture grouting through inclined steel sleeved port pipes below the organics. The trial was instrumented with multi-anchor rod extensometers, in-place inclinometers and vibrating wire piezometers to obtain the ground response to grouting activities. This paper presents the data collected and discusses the effectiveness of the grouting program, including influence of drilling methodology and consequential impact of generated pore pressures in the organics layer.
