RoadCem is a patented additive used to enhance cement based soil stabilisation. It is an inert blend of Noble and non-Noble metals, together with synthetic zeolites which combine to give a catalytic reaction to the cement hydration, enabling the formation of needle like crystalline structures within the bound materials. RoadCem is defined as a ‘Nano Technology’ because its effects can only be seen with the aid of a high powered microscope – whilst its performance benefits can be more readily seen in its superior strength and flexural stiffness.
Cement soil stabilisation allow in-situ soils of any type to be bound to create a stiffened, highly durable layer to replace imported aggregate often used as the base component for haul roads, site compounds and working platforms for heavy plant and equipment. RoadCe soil stabilisation can be designed to meet the highest of loading and durability requirements.
With its high flexural stiffness and strength RoadCem has been used worldwide for road construction and uniquely it can be used without any wearing course or running surface, making it totally recycleable when used for temporary works.
These unique qualities provide important construction advantages over alternative soil stabilisation methods:
You may be unfamiliar with soil stabilisation and have many questions you would like answers to. A good starting point is to scroll through our list of FAQ’s to see if it helps you. If not we are always happy to take your call and discuss further.
Temporary soil stabilisation has a wide range of applications as illustrated in the Case Studies section below. Additional technical information and reference technical papers and reports on RoadCem stabilisation can also be found under the Additional Information tab below.
UK heavy clays and glacial till deposits are notorious for having high sulphate contents. See how RoadCem soil stabilisation can mitigate any secondary swelling of such soils – Mitigation of Sulphate Heave in Cement Stabilised Soils – Coventry University Sept 2020 –
The use of soil stabilisation as part of the permanet works is often an overlooked concept. A RoadCem stabilised layer can provide a robust, high performance foundation for roads, car parks and under concrete slabs – allowing for the elimination or reduction in the thickness of the granular capping and sub-base layers. See our Case Studies and Additional Information below.
