of the Three Types of Cement Engineered Soils

Cement-Modified SoilCement-Stabilized BaseFull-Depth Reclamation with Cement
PurposeImproves the soil-bearing capacity.

Facilitates laying and construction of the foundation.

Reduces the plasticity index.

Provides an excellent base for construction.
Provides a solid base layer for road paving.

Meets minimum durability and resistance specifications required for a project.
Is strong and frost-resistant.

Provides a solid base layer for road paving.

Recycles pavement.
MaterialsCohesive soil, silt-clay-sand mix.

3% to 5 % PROBase™ cement added.
Natural mixes of soil, gravel-sand, silt-clay.

Also aggregates or aggregates and soil mixes.

4% to 10% PROBase™ cement added (mixed on site with a cement spreader).

3% to 6% of PROBase™ or CompactCEM™ cement added (Pugmill mixing plant).
Spray-coated mix with granular materials from the foundation or sub-foundation.

Respects the limits of aggregate granulometry.

3% to 6% PROBase™ cement added.
