Special Issue: Novel Technologies for Grouting, Jet Grouting and Soil Deep Mixing

Submission status

Ground improvement methods involving the addition of binders to in situ soils have become traditional for geotechnical engineering. The different techniques can be broadly classified as:

• Injection and/or Grouting (e.g. Permeation Grouting, Compaction Grouting);

• Jet Grouting and Soil Deep-Mixing (wet and dry methods);

Grouting refers to the injection of pumpable materials into a soil or rock formation, which hardens over some time to change its physical characteristics, e.g. Cambefort (1977); Mitchell (1981). Jet grouting and soil deep-mixing (SDM) technique involve the mixing of soil with binder applied in the form high or low-pressure jets (Croce et al., 2015). SDM involves ‘mixing by rotating mechanical mixing tools where the lateral support provided to the surrounding soil is not removed’ (prEN 14679, 2005). Ground improvement relies on conventional Ordinary Portland Cement (OPC). However, other materials, which can be called non-conventional binders, are used as an alternative to OPC for ground improvement purposes, such as colloidal silica, resins, micro-fine cements and geopolymers.

The use of chemical products in supporting these techniques has become almost unreplaceable for solving issues, such as penetrability or low-permeable soils, liquefaction mitigation or support of jet grouting and deep-mixing applications in cohesive soils, where cement content is normally increased to provide the treated soil a minimum unconfined compressive strength requirement (e.g. Burke, 2004).

The special issue in Geotechnical and Geological Engineering would cover these aspects and disseminate novel technologies in the field to support researchers and practitioners to have the latest advance in geotechnical ground improvement.
