Cement Stabilisation
Cement stabilisation involves mixing controlled quantities of cement into soils or granular materials to create a highly durable, load-bearing layer tailored for Irish construction projects.
What Is Cement Stabilisation?
Once compacted and cured, this treated material acts as a robust foundation. Cement reacts with water and the fines within the material to form a hardened matrix, significantly increasing strength and stiffness. It is frequently used for:
- Capping layers
- Sub-base layers
- Cement Bound Granular Mixtures (CBGM)
- Elements of the permanent pavement structure
Typical Applications in Ireland
Cement stabilisation is particularly attractive where projects seek to reduce imported stone thicknesses, make the best use of site-won materials, and achieve durable performance under demanding traffic loads.
Benefits of Cement Stabilisation
Engineering Benefits
Significant increase in strength and stiffness. Reduces long-term settlement and deformation while improving resistance to trafficking during construction.
Cost & Programme
Massive reduction in imported aggregate volumes and lower disposal requirements. Faster construction of capping means fewer lorry movements and reduced haulage costs.
Environmental Focus
Lower carbon footprint compared to traditional dig-and-replace. Increases the reuse of site-won soils and heavily reduces reliance on quarries.
Our Cement Stabilisation Process
Our approach ensures quality at every step of the process:
Investigation & Testing
Working with independent labs to determine suitable dosages and evaluate target strengths for the host materials.
Binder Supply & Storage
Cement is delivered in bulk and stored securely on-site, ready for precision calibrated spreading across the treatment zone.
Mixing & Incorporation
Our specialist plant homogenously mixes the cement and necessary moisture through the soil to the exact specified depth.
Compaction & Curing
The layer is trimmed, finished to line and level using suitable heavy rollers, and allowed to cure fully to prevent premature trafficking damage.
Quality Control
Rigorous on-site density testing and laboratory strength testing are carried out to confirm full compliance with the specification.
Combined Lime and Cement Solutions
On many Irish sites, cement stabilisation is used alongside Lime Modification. Lime is first used to dry wet cohesive soils (like glacial till), and cement is then added to achieve the massive long-term strength required for capping or sub-base layers.
