Cellular
Concrete

Cellular concrete (LDCC) is a lightweight fill made by mixing cement, water, and preformed foam. It has densities from 20 to 90 lb/cuft. CJGeo can produce up to 600 cubic yards per hour. Commonly used in geotechnical and utility work, it’s ideal for trench backfill and void filling.

Polyurethane
Grouting

Polyurethane grouting is a clean, fast, and minimally invasive method for stabilizing soils and lifting concrete. It’s more efficient than cement grouting. Common uses include repairing highways, commercial slabs, and industrial floors suffering from settlement or instability issues.

Chemical
Grouting

Chemical grouting involves injecting noncementitious materials like acrylates, resins, and prepolymers into the ground. It strengthens soils, seals leaks, and controls groundwater. This technique is often used in tunnels, foundations, and below-grade structures for stabilization.
