SOIL STABILISATION
Soil stabilization involves the improvement of soil properties by implementing chemical and mechanical techniques. Binders such as cement and lime enhance stabilization in soils, developing their engineering properties and generating an improved construction material
DAG Civils currently offers ground stabilisation and ground improvement works to client’s requirements within the East Anglian region. Our integrated cement hopper and mixer unit is fully automated to give consistent distribution of lime or cement throughout the processes, giving a quality product every time
BENEFITS
Here's just some of the benefits choosing to work with the existing soil on-site can bring to your project:
•Reduced Co2 emissions (approximately 440 pounds of Co2 for every ton of construction material transported one mile)
•Up to 20% improved lifespan for lime-treated soils (and reduced maintenance costs)
• Improved recyclability (over 80% of lime-treated soils can be recycled or repurposed for other construction projects)
• Up to 100% improved CBR
• Up to 40% cost savings

ABOUT SOIL STABILISATION
Soil Stabilisation & Modification is a trusted technique that improves the engineering properties of weaker soils during earthworks operations.
This technique particularly suits both temporary working platforms such as; compounds, haul roads, storage areas, piling mats and permanent replacement of capping layers and sub-bases.
During winter, or adverse weather this technique can also improve the general trafficability of sites.
This method replaces the traditional and costly approach of importing vast quantities of bulk aggregates and significantly reduces or avoids the removal and disposal of surplus subsoils to landfill.
Ground improvement works, where lime can be mixed into wet soils to dry and revitalise previously unsuitable material, can be a cost and time saving process for clients within construction products. Especially where fill material is to be reused on site. On comparison with removing the unsuitable materials and importing fill or waiting for the unsuitable material to become drier and useable again, both are costly options and ground improvement with lime is definitely a viable option to progress the works in a cost-efficient manner.
Ground stabilisation is the process of adding cement into soil or a material to form a fully bound product which acts as a sub-base or foundation. NCC utilise stabilised foundations for their road network where applicable as it is a great way of utilising material on site. This provides a road sub-base which does not require imported primary aggregates and is overall quicker to install. The typical cost saving compared to a traditional Type 1 primary sub-base foundation depth is between 40-50%.
Another use of ground stabilisation is in the form of temporary work when installing haul roads, temporary accessed and compounds. We have even stabilised ground down to a depth (and back up again) to dig deep foundations through, where the ground conditions had been poor, and this removed the need to move to a piled design. Temporary works can be very cost efficient to install, as the ground is stabilised insitu and the only import of material is the protection running layer. The saving for the excavation and installation of imported aggregates and geogrids, can reduce the direct cost of materials and time installing. On completion the protection layer can be removed and re-used/disposed off site and the stabilised layer broken up again and left insitu for incorporation into the works.
DAG Civils have completed works for numerous private clients from haul routes, crane pads, compounds and accesses over the last 2 years. Along with major construction clients such Allison Homes, Jackson Civils, Orsted, Overmill and NCC indirectly through developer 278 works.
