ssoil stabilisation


Through our international distributorship with the Australian innovator of Claycrete soil stabilisation, we are able to offer products to stabilise clay-bearing soils that can reduce the capital cost of unsealed roads by up to 50%, compared to alternative stabiliser additions, such as laterite. Claycrete soil stabiliser can also be used to provide the foundation under ‘chipseal’ surfaces, which can reduce the capital cost of sealed roads by up to 70%, compared to laterite foundations and asphaltic concrete (or ‘blacktop’).
Claycrete is an innovative three-part building solution that consists of proprietary chemical science, a unique soil mixing methodology that is adjusted for local situations, and implementation management personnel who oversee the process. When traditional paving options are either too expensive or not accessible, Claycrete has a solution. Using our engineering and road building expertise, we have mixed Claycrete products with clay-based and calcareous/limestone materials to create sub bases, sub grades, base courses, pavements, running surfaces and staging areas for numerous projects, including haul roads, unsealed/sealed roads, drill rig areas, airstrips and more. Claycrete roads also help you meet your Health, Safety and Environment objectives. Claycrete products do not harm humans, plants, animals or drinking water, and they don’t leach into the environment. Claycrete’s effect on materials and soils is permanent and irreversible, with no residual products in the ground or pavement. Claycrete has been tested for acute oral toxicity (LD50) by SGS and is certified as having no toxic effects at concentrations in excess of 5,000mg Claycrete per kg body weight. Claycrete is the only soil stabilisation product that has achieved this result.
CBAC is sole international distributor for Claycrete soil stabilisation products in the following regions and countries:
  • placeNorth Asia
    China - Mongolia - Taiwan - Japan - South Korea - North Korea

More information about Claycrete, including technical specifications, can be found at:

Products & Services

The Claycrete product range allows the offering to be applicable to about 80 percent of the world’s soil materials. These products work only when properly matched with the Claycrete process of soil mixing and implementation.

What makes it better?

On conventionally built, non-sealed roads, surfaces are constantly deteriorating. Wet conditions turn roads into mud paths. In dry conditions, equipment usage and wind combine to constantly blow fine materials and produce large amounts of dust. Mud causes slippery conditions that slow the work progress and cause accidents; it lubricates tyres and makes them more susceptible to cuts; and it can remain in place for weeks and cause long-term effects on productivity. Dust can cause poor visibility, and it creates health and safety concerns for employees and possibly for neighbouring communities. Both mud and dust increase rolling resistance and cause accelerated internal wear on machines. When Claycrete is used to create permanent all-weather pavements, the road infrastructure is transformed to create improved running surfaces no matter the conditions. Wet conditions benefit from improved tyre friction and decreased mud. Dust is decreased in dry conditions and protruding rocks and rough road surfaces that take a toll on equipment and tyres are eliminated.
In addition to savings in capital expenditure, Claycrete soil stabilisation also promises:
  • Reduced on-going maintenance costs.
  • Safer roads for goods and passenger transport.
  • Improved all-weather mobility and year-round access to markets for rural communities.
  • Dust suppression amidst health & safety concerns for local communities and mining operations.

Environmental Sustainability

Claycrete soil stabiliser is environmentally friendly, having an LD50 of 0 in concentrations up to 5,000mg of Claycrete per kg body weight. The product has been extensively applied in a number of countries, including Australia, Canada, Indonesia, Thailand, Ghana, and Rwanda. We work with governments and local contractors to build stronger, better, and more cost-effective roads. In addition to soil stabilisation products, we provide technical assistance and capacity-building for local people, not only in the optimal application of soil stabiliser products, but also in the engineering design and construction of sealed and unsealed roads for improved durability.

industries & applications

Claycrete can be implemented almost anywhere in the world where there is access to fresh water, proper equipment and competent operators.

Its many infrastructure applications include all-weather unsealed roads; sub-base and base course treatment for sealed roads; airstrips; and sub-base and base preparation for structures such as buildings, oil rigs, parking lots, rail beds, miscellaneous hard stand areas and wind towers.


Mines have a critical need for low-cost roads in remote areas. Mines are often not located close to a significant infrastructure network, yet they need to move large quantities of material to a port. In addition, the initial investment required when starting a mine is very onerous, especially prior to the start of revenue generation.

Claycrete roads are a cost-effective and timely solution compared with asphalt roads and rail lines; and Claycrete helps mine sites meet their Health, Safety and Environment goals.


Claycrete is a good road building solution, whether it is used to replace unsurfaced roads or improve the base of existing roads. Even in highly-developed countries, there are considerable lane-miles of unsurfaced (gravel) roads. Using Claycrete on these roads will reduce maintenance and provide an improved all-weather surface. Claycrete improves surfaced roads by creating an improved solid base that is impervious to water damage.


Roads in plantations and logging operations often become impassable during rainy periods, making harvesting impossible. Claycrete can turn these roads into permanent all-weather roads that require little maintenance.

Claycrete products have no negative effect on the soil and do not leach into adjacent areas. Roads can easily be removed by simple ripping, and then the area may be replanted.


Claycrete is a good solution for oil and gas field well-pad construction and service roads. Initially it is necessary to bring expensive, heavy drill rigs to the site. Later, during drilling operations, a pad must be available to the support the rig. In addition, access roads must be maintained to allow 24/7 service in case of failures or injuries. Currently, roads in this industry are expensive due to required barring capacities, the need for extensive maintenance, and their quick deterioration.

claycrete process

Many types of soils available throughout the world are high in clay content and typically not considered suitable for road construction. Clay is prone to swell and shrink based on the presence or absence of water.

Claycrete resolves these problems by altering the clay particles on a molecular level, permanently changing the clay into an environmentally friendly binder of soil materials and it no longer attracts water.

Claycrete allows the clay particles to permanently break their bond with water. Once this happens, the clay particles can be compacted very tightly, binding all other soil materials.

Claycrete Process

The Claycrete process follows the following steps:

Site Analysis

Experts complete a survey to assess on-site materials, understand conditions and determine issues and infrastructure requirements. This process evaluates a site to determine how Claycrete can successfully be used to improve roads and airstrips. When it is determined how Claycrete can be used with the local soils, the customer receives a proposal that presents a tailored Claycrete solution.


Resources are mobilized for implementation. The site has several options for completion of the work, including using its own personnel and equipment, hiring a local contractor to complete the project, or partnering with Claycrete for personnel and equipment.

Hands-On Implementation Services and Training

Claycrete project managers provide on-site implementation and training.

Claycrete experts are hands-on every time Claycrete Stabilier is implemented to ensure that the soil methodology and implementation process is followed and adjusted for local weather conditions so that the benefits are delivered.

Post Treatment Auditing

Claycrete project managers offer auditing services 3 to 6 months after the construction of the road to ascertain the effectiveness of the treatment and to identify areas of improvement.

cconsulting services

engineering services

CBAC provides consulting services focused on organisational sustainability, from Engineering services and comprehensive Project Management for soil stabilisation and chip seal road construction, to Sustainability reporting to achieve Operational Excellence for large corporation.

Engineering Services

CBAC provides engineering services in the design and construction of unsealed roads. Our services focus on:

  • Technical guidance and techniques.
  • Environmental practices to avoid, remedy, or mitigate adverse effects on local communities.
  • Occupational health & safety practices to protect the local labour force during construction.

We design roads at minimum capital cost, and that will perform the following functions with an acceptable level of maintenance:

  • Protect sub grade from water so the strength of underlying soils is maintained.
  • Provide a surface that is safe for passengers and goods.
  • Ensure all year round access to markets for local communities.

We achieve the above criteria in our design with proper road profiling to facilitate drainage, and with the use of Claycrete ionic soil stabiliser. It is essential to recognise that soil stabilisation does not override the necessity for well-designed roads with proper drainage. Such road profiling typically takes the form of that shown below:


Our design and construction process takes account of subgrade properties, soil compaction requirements, and optimum moisture content (OMC) of the subgrade to be stabilised (usually 15-20% for maximum dry density). We conduct California Bearing Ratio (CBR) tests before and after the application of Claycrete, with the following results expected:


project management

In line with our philosophy and principle of ‘operational excellence’, we provide project management services for road construction. We apply our knowledge, skills, and techniques to project activities to meet the project performance objectives focused on quality, schedule, and budget. We will work with contractors to design a project schedule, and then apply our Quality Management System, Environmental Management System, and Occupational Health & Safety Management System to achieve optimum project outcomes.

We have engineers and project managers experienced in the use of design reviews and project risk identification techniques. Each risk identified is scored on a set of impact/consequence conditions, and probability conditions with the overall risk found using a typical risk matrix. Each project risk above a threshold is then mitigated and re-assessed to determine the success of the particular mitigation strategy.

At all times, we seek to achieve project outcomes by working in cooperative partnerships with clients and contractors.

Risk Matrix

sustainability report

The term ‘sustainability’ is simply defined as the capacity of systems and processes to endure over time. Stakeholders now demand that organisational sustainability be built on a Triple Bottom-Line, each of which must be in harmony for organisational systems to prosper into the future:

  • Economic: Organisations must be cost-effective.
  • Social: Organisations should make a positive contribution to local communities.
  • Environment: Organisations should be eco-efficient & not damage the natural environment.

In dealing with sustainability in the 21st century, and a context characterised as complex, dynamic, and hyper-competitive, just having a strategy or business plan is not enough – ‘operational excellence’ is the critical component, which should link to, and emerge from, the strategic intent of the organisation.

Operational Excellence is the ability to connect strategy with implementation for superior performance

While the definition may appear simple, contextualisation and implementation is complex, and dependent on a number of basic criteria:

  • Strategy linked to Key Performance indicators (KPIs) to focus implementation.
  • Performance measurement linked to benchmarks & KPIs (results-based management).
  • A corporate culture of excellence & continuous improvement.
  • Employee commitment to deliver excellent outcomes to clients.
  • Cross-functional teamwork empowered to achieve innovation.
  • Holistic whole-of-organisation thinking based on a standardised process to achieve continuous improvement outcomes.
  • Leadership commitment to drive change, whether continuous improvement fostered by performance metrics; targeted interventions prompted by external threats or opportunities; or, transformational programs as a result of market discontinuities.

Operational excellence, as measured by Triple Bottom-Line performance metrics, leads to efficiency and effectiveness, and fosters sustainability into the future. But how does an organisation monitor and report to stakeholders on such positive outcomes?

The answer is by way of a Sustainability Report, created to inform internal and external stakeholders about the company’s economic, social & environmental performance. It assists the organisation to monitor and continually improve performance metrics across the Triple Bottom Line.

Indeed, sustainability reporting is valuable to an organisation for a number of reasons:

  • To be seen as a leading organisation, in terms of global engagement, professionalism, eco-efficiency & community contribution.
  • To unify the organisation with a common overarching objective.
  • To support employee commitment to KPIs & continuous improvement.
  • To engage employees in broader community issues, such as volunteerism & environmental stewardship.
  • To align with core values.
  • To recognise increasing pressure of socially responsible investment funds and venture capital, and their demands for ethical behaviour.
  • To support the global community in the aspiration for greater eco-efficiency, as envisaged by the Sustainable Development Goals (SDGs), UN Global Compact & 2015 COP21 Paris Conference on climate change.
  • To retain market share, and gain access to government and private-sector contracts.

The most common framework for sustainability reporting is the Global Reporting Initiative (GRI). GRI is a non-profit organisation founded in 1997. It assures sustainability reporting standards, and contributes to building a sustainable world. GRI improves those guidelines every few year with revised standards. In May 2013, the GRI published its G4 guidelines.

CBAC operates its projects and consulting services in accordance with the principles of operational excellence, sustainability, and GRI reporting. We can provide consulting services to help your organisation, whether private sector, non-government, or government entity, to also achieve such aspirations.

In addition, for organisations wishing to expand globally, we help build and maintain effective cross-cultural business relationships, which are critical to the achievement of strategic objectives. We are specialists in the fields of international business facilitation and cross-cultural coaching across a broad range of industrial sectors.

Our people have substantial international experience and qualifications in related fields with a focus on developed and emerging markets in Asia and Africa. We partner with our clients to bridge cultural and business contexts by providing bespoke services that enable:

  • Informed strategic decision-making for international expansion
  • Collaborative international alliances and joint ventures
  • Sustainable business and operational strategies
  • Effective multicultural team performance
  • Competent intercultural leadership, communication, and negotiation.
