Soil Stabilisation Explained
Soil Stabilisation is used to improve the engineering properties of weak soils used for base courses, sub-base courses and subgrades with the use of lime or cement binder.
The long-term properties of the wet or weak soils will be vastly improved once rotavated and compacted.
Lime Stabilisation
- Lime can be used to treat soils in order to improve their workability and load bearing strength.
- Lime is frequently used to dry wet soils, reducing downtime and providing an improved work surface.
- The use of lime will increase the stability, impermability and load-bearing capacity of weak site-won material.
Cement Stabilisation
- Cement stabilisation will improve soils that are unsuitable for use on-site.
- The addition of cement to weak soils will decrease plasticity and increase the bearing strength of the soils.
- By increasing the shear strength of the soils, it will provide a stable, hard-wearing platform on which construction can take place.
