“…The principal objectives of this paper is to collate latest advances in materials, methods and models that underpin these novel ground engineering interventions, to discuss their development and deployment within the biomimetic or bio-inspired innovations context, and their common deliverables: (1) preserved permeability and porosity, (2) balanced water retention and conveyance capacity, (3) durability in the face of low-order cyclic, transient or extreme-but-one-off actions (thermo-hydrochemo-mechanical), (4) enhanced strength, stiffness and particularly small-strain stiffness, (5) enhanced steady states (quasi-steady state, ultimate steady state, phase transformation, critical state) and relaxed flow potential, (6) enhanced resilience in the face of extreme events, (7) adaptability to wider loading environment: hydrodynamic, cyclic, and anisotropic.…”

The ground is a natural grand system; it is composed of myriad constituents that aggregate to form several geologic and biogenic systems. These systems operate independently and interplay harmoniously via important networked structures over multiple spatial and temporal scales. This paper presents arguments and derivations couched by the authors, to first give a better understanding of these intertwined networked structures, and then to give an insight of why and how these can be imitated to develop a new generation of nature-symbiotic ground engineering techniques. The paper draws on numerous recent advances made by the authors, and others, in imitating forms (e.g. synthetic fibres that imitate plant roots), materials (e.g. living composite materials, or living soil that imitate fungi and microbes), generative processes (e.g. managed decomposition of construction rubble to mimic weathering of aragonites to calcites), and functions (e.g. recreating the self-healing, selfproducing, and self-forming capacity of natural systems). Advances are reported in three categories of Materials, Models, and Methods (3Ms). A novel value-based appraisal tool is also presented, providing a means to vet the effectiveness of 3Ms as standalone units or in combinations.
