Soil Stabilisation
Cost effective and sustainable!
Soil stabilisation is a specialist process used as an alternative to the traditional practice of removing weak or unsuitable soils and importing granular fill materials.
We offer our clients full technical support from scheme feasibility through to end product testing, all provided by a team with market leading knowledge and experience.
Soil Stabilisation is a cost effective, sustainable method of treating weak or unsuitable soils in situ, eliminating the need for importing capping and sub-base materials.
It provides a far superior alternative to unbound granular fill and Type 1 sub-base layers with CBR base materials.
The process is fully detailed and supported in the ‘Specification for Highway Works’.
Allasso enable their clients to maximise the potential of the existing material and eliminate the need for costly and unsustainable disposal and import.
The Benefits

Environmental
- Zero waste from site
- Significantly reduced energy consumption and a lower carbon footprint
- The existing site material is used as a structural layer
- No need for imported virgin aggregate
- Significantly reduced lorry movements
- Significantly less disruption to the surround highway network

Construction
- Significantly quicker construction time
- Significantly greater stiffness and strength compared to traditional unbound aggregates
- The material quality is monitored throughout the works
- Bespoke designs for individual sites

Cost
- Reduced Transport costs
- No disposal costs
- No cost for importing aggregate
- Reduced Site Management costs due to shorter works duration

The Process

The process begins with an initial site investigation, with trial holes and samples taken and tested.
Using the results of the laboratory testing and other site data, a design is reached according to the intended application and client specification.
Once on site, the in situ construction process begins with the spreading of the binder(s), which is then followed by the binders being mixed with the soil to the required depth.
Finally, the site is then graded and compacted to the required levels and curing membrane applied.
Throughout the process a UKAS accredited specialist laboratory technician is present ensuring material quality, specification and compaction are achieved. End product testing confirms the specification has been achieved. This quality control ensures that the finished product provides the material and structural performance required.
Alternatively the process can be delivered ex situ using our mobile plants.
