PRODUCT DEVELOPER AND MANUFACTURER OF NME FOR THE ROAD INDUSTRY.

ABOUT US.

Operating both nationally and internationally, Geonano Technologies is widely recognized as a leader in the development and implementation of advanced, scientifically proven nano based solutions for road pavement design and construction and maintenance thereof, in alignment with SANRAL’s TRH24 guidelines for road pavement maintenance and the COTO standard specifications.

In-House Innovation

Our dedicated Materials and Product Research Laboratory, based in South Africa, conducts rigorous material evaluations and emulsion testing. This facility ensures that every product we deliver is backed by robust scientific validation and quality control.

Academic Collaboration for Engineering Excellence

We are proud to collaborate with Africa’s highest-ranked Faculty of Engineering, sponsoring final-year and postgraduate students. This partnership strengthens the scientific foundation of our products and fosters innovation through academic insight.

Nano Technology at Work

Through close engagement with students and researchers, we’ve identified and integrated the most effective nano technologies into our product line. These innovations have led to enhanced formulations and optimized design methodologies grounded in fundamental engineering principles making our solutions universally applicable across diverse geotechnical environments.

Cost-Effective Infrastructure Solutions

Our technologies enable significant reductions in road construction unit costs. By using safe, material-compatible modifying agents, we chemically enhance traditional stabilizing agents such as bitumen  & polymer emulsions. This process allows the stabilizer to form strong chemical bonds with naturally available aggregates stone, gravel, and soil far surpassing the performance of conventional methods that rely solely on mechanical interlocking and absorption.

Superior Performance Across All Pavement Layers

These high-strength chemical bonds dramatically improve durability and load-bearing capacity, enabling the use of local materials in all pavement layers. Our solutions consistently meet and often exceed engineering standards for stress, strain, and long-term resilience, contributing to reliable, cost-effective transportation infrastructure.

 Real-World Validation

Studies and field trials, such as those conducted in SANRAL-funded community development projects, have shown that NME-treated roads outperform traditional methods in both durability and environmental impact.

“As we progress on our journey, Geonano Technologies wishes to express its thanks to the engineers and academic mentors that have believed in our vision from inception and have shared our passion for innovation. Their selfless support has proved invaluable. NME technology is proven and the answer for Africa’s cash-strapped roads industry,”

PRODUCT DESIGN & TECHNOLOGY.

Once materials have been tested and the minerology of the material has been identified, we are then able to provide a ‘material compatible’ modified emulsion. NME technology is NOT based on a ‘Trial and Error’ approach, but on the identification of the inherent material minerology and material particle size. Once identified we can safely Incorporate the modifying agents that chemically modify traditional stabilising agents, such as Bitumen Emulsion. This modification enables the stabilising agent to chemically attach to the naturally available stone/ gravel/ soil materials. 

The chemical attachment that is absent in normal bitumen emulsion products (that relies on electrical and mechanical forces, through interlocking and absorption to gain strength) considerably improves bond strengths. 

These high chemical bond strengths enable the use of naturally available materials in all pavement layers of roads, meeting (usually exceeding by some margin) the engineering requirements in terms of stresses, strains and durability in any pavement layer. These modified emulsions are not ‘Load sensitive’ and can therefore be used for all pavement designs from Low Trafficked Roads to Super Highways. 

Through the advancement of these technologies, they can now successfully be introduced into other areas, including, primes, bituminous layers, gravel road seals, labour intensive slurry seals, Pot Hot Repair solutions, various types of fog sprays and dust suppressants, structural protection as well as the recapitalisation of waste materials i.e slag, slime, coal etc and even the re-pelletising of coal dust. ‘Notably, all these applications are applied cold’, negating the need for special heating requirements and expensive machinery.

This Environmentally Green technology contributes immensely to the conservation of the natural environment and limited resources and further curbs the negative impacts of human destruction.
