When applied, they react with soil components to improve compaction, reduce permeability & increase strength without harmful chemicals. Enzyme-based stabilization is eco-friendly, suitable for specific soil types & often used in low-traffic roads, paths or agricultural applications.

How Does Soil Stabilization Help With Expansive Soils?

Soil stabilization helps with expansive soils by reducing their plasticity, shrink-swell potential & moisture sensitivity. Chemical additives like lime or cement alter the soil's structure, forming stable compounds that limit volume changes. This improves strength, minimizes cracking & ensures stable foundations, making construction feasible on soils that typically pose structural challenges.

What Safety Precautions Are Needed During Soil Stabilization?

Safety precautions during soil stabilization include wearing personal protective equipment (PPE), ensuring proper handling of chemical additives like lime or cement, controlling dust, securing machinery operation zones & monitoring air quality. Workers must follow site-specific safety protocols, receive proper training & ensure environmental safeguards to prevent contamination, exposure risks or equipment-related injuries.
