Stabilisation

Professional stabilisation using methods suitable for the project

Column stabilisation

Column stabilisation is a deep stabilisation method in which the soil is reinforced without removing any ground by adding a lime and cement-based binder to the soil. The drill of the stabilisation machine is drilled to the desired depth, and when the drill is pulled up, the binder is driven into the ground while mixing at the same time. The column structure is formed when the binder reacts with soil moisture.

Column stabilisation is an option for reducing the foundation costs compared to foundation on piles, for example. Deep stabilisation is particularly suitable for the soil stabilisation of extensive project areas. It is quite competitive as a foundation reinforcement method.

We have long experience in deep stabilisation and we are pioneer users of the method. We have developed a mechanical stabilisation control system, and updated, reliable documentation and quality assurance form a central part of our service.

Our stabilisation fleet is the top of its class. All our stabilisation machines are fitted with a satellite positioning system and automated reporting system covering all the report data recommended in the infraRYL guidelines.

Areas of application:
•  Streets, pipes etc. technical maintenance network
•  Prevention of harmful sinking
•  Improving the stability of an excavation or an embankment
•  Improving the load-bearing capacity of ground
•  Structures in slopes or cuts
•  Levelling out depressions
•  Different kinds of transitional structures
•  Improving the stability

Mass stabilisation

In mass stabilisation, the ground is reinforced by adding a lime or cement-based binder to the soil mass. The binder is mixed with the soil using a mixer machine tip that is moved both vertically and horizontally in a lamellar manner. The binder reacts with soil moisture, creating slab-like, uniformly reinforced zones that can be used as the foundation of soil structures like when building on load-bearing ground.

Mass stabilisation can be used instead of mass replacement, savings both money and time. Mass stabilisation is particularly suitable for the soil stabilisation of extensive project areas. It is quite competitive as a foundation reinforcement method.

Areas of application:
• Road, street and railway embankments and different kinds of yard and storage areas
• Stabilisation of clay, peat, sludge or silt
• Prevention of harmful sinking
• Improving the stability
• Improving the load-bearing capacity of ground
• Remediation of contaminated soil
