SST Soil Stabilization Technology

SST Technology: Definition and Operating Principles

A soil solidifier is an engineering material formulated from a composite blend of various organic and inorganic substances or biological enzymes. Its core mechanism of action involves a series of complex physicochemical reactions that alter the surface charge properties of soil particles and compress the electrical double layer on their surfaces. This process effectively disrupts the adsorbed water films situated between soil particles, thereby facilitating the rapid formation of a stable skeletal structure by inorganic or organic cementing agents.

01. Ion Exchange

Converts the hydrophilic groups on the surface of soil particles into hydrophobic groups, thereby reducing water content.

02. Structural Formation

Promotes the rapid formation of a cementitious material framework, thereby filling the voids between soil particles.

03. Rapid Solidification

Rapidly and efficiently dewaters and solidifies materials such as soil, sand, and slag, forming a stable soil mass.
