What is Biocementation for Soil Stabilization?

Biocementation for soil stabilization uses microbially induced calcite precipitation (MICP) to enhance soil shear strength, reduce permeability, and prevent erosion in geotechnical engineering.

MICP involves ureolytic bacteria precipitating calcium carbonate to bind soil particles (Cheng et al., 2013, 723 citations). Research optimizes bacterial strains, nutrient delivery, and saturation levels for field applications (Dhami et al., 2013, 697 citations). Over 10 key papers since 2012 document lab-to-field scaling (Mujah et al., 2016, 512 citations).

Key Challenges

Why It Matters

Biocementation replaces Portland cement stabilizers in erosion-prone slopes and liquefiable sands, reducing carbon emissions by 80% in soil treatment (Montoya et al., 2013). Field trials show 200-500% unconfined compressive strength gains in sandy soils (Cheng et al., 2013). Applications include dam foundations and coastal defenses, with economic savings from lower material transport (Shahin et al., 2016). Dhami et al. (2013) highlight MICP's role in sustainable infrastructure for seismic zones.

Key Research Challenges

Scalability to Field Conditions

Lab MICP achieves high calcite content, but field percolation reduces uniformity due to heterogeneous flow (Cheng and Cord-Ruwisch, 2013). Surface treatment protocols struggle with deep soil penetration (Mujah et al., 2016). Optimizing injection sequences remains critical for large-scale erosion control.

Saturation-Dependent Precipitation

Calcite formation drops sharply above 80% saturation, limiting wet soil applications (Cheng et al., 2013). Bacterial survival and urease activity vary with moisture, impacting shear strength gains (Shahin et al., 2016). Dry percolation methods show promise but require precise timing (Cheng and Cord-Ruwisch, 2013).

Long-Term Durability

MICP-treated soils face microbial die-off and carbonate dissolution under cyclic loading (Montoya et al., 2013). Liquefaction resistance holds in centrifuges but needs validation for multi-year exposure (Mujah et al., 2016). Enzyme-induced alternatives achieve strength at lower carbonates but lack aging data (Almajed et al., 2019).
