Creating durable, strong surfaces is the mandate for many civil engineers, roadworkers and construction companies in South Africa. Achieving this stability can be especially difficult in our diverse ecosystems, which include both high-rainfall and desert regions. Speciality chemicals are often needed to build roads, runways and paths without concrete or asphalt.
Gold Reef Speciality Chemicals produces various high-performance, bespoke chemicals for several industries in South Africa, including civil engineers. Our commitment to world-class chemicals is complemented by our unique speciality services that help us guarantee the ideal products for your company. One such chemical is our Glodust dust suppressants.
These customised chemicals are used for surface stabilisation and hardening the substrate to prevent dust and erosion. Our dust suppressants are commonly used to build dirt roads, trails and even runways; making them perfect for various industries, including farming, game reserves, mining, construction and aviation.
Water-based polymers are increasingly being used as a sustainable solution for stabilising eco-friendly roads and runways. These polymers, often derived from non-toxic, environmentally safe materials, are designed to bind soil particles and aggregates effectively, enhancing the strength and durability of surfaces while minimising environmental impact.
When applied, water-based polymers penetrate the soil, creating a cohesive matrix that reduces erosion, dust, and the need for frequent maintenance. Unlike traditional stabilisers, such as asphalt or cement, these polymers do not rely on harmful chemicals or energy-intensive processes, making them an eco-friendly alternative. Additionally, their water-soluble nature allows for easier application and minimal disruption to local ecosystems.

The importance of dust suppressants for surface hardening
Dust suppressants are sprayed on surfaces to reduce and manage dust particles that float up into the air when vehicles or foot traffic travel along the substrate. These particles of sand or soil not only affect visibility and the quality of the air we breathe, but they also settle downwind and create dirt and unhygienic environments elsewhere.
When it comes to roads and runways, dust impairs vision, which affects the safety of cars and aircraft using the surface. Effective dust control is not just an environmental obligation but also a vital operational requirement for civil engineers.
It minimises environmental degradation, lowers maintenance costs, increases safety, and improves air quality. In South Africa, where mining, farming, and infrastructure development frequently occur in dust-prone areas, these speciality chemicals are especially important.
One of the key benefits of water-based polymers is their ability to work with a wide range of soil types, including sandy, silty, and clay soils, making them versatile in diverse geographical conditions. They also improve load-bearing capacity and surface resistance to weathering, ensuring roads and runways remain stable under heavy traffic and extreme weather conditions.

Creating bonded surfaces with dust suppressants
Conventional techniques for building long-lasting surfaces, such as using asphalt or concrete, can be costly and resource-intensive. Speciality dust suppressants are an economical and sustainable alternative as they directly form a bonded surface from pre-existing soil and aggregate.
These chemicals, usually made from polymers, resins, or other binding agents, penetrate the surface and react with the soil or sand particles to create a hard agent, much like glue. They hold the soil particles together and provide a stable and long-lasting crust. The load-bearing capacity and erosion resistance of the treated surface are greatly increased by this chemical stabilisation.
Some dust suppressants work by binding fine particles together to prevent them from becoming airborne when disturbed by tyres. Others produce a surface coating that traps dust and stabilises the surface. There are complex molecular interactions that take place when these chemicals are applied to soil or sand surfaces.
For example, polymers create lengthy chains that bind and entangle soil particles. Resins, on the other hand, strengthen the surface matrix with a cross-linked network of molecules. This is why the specific chemical formulation is so important because it needs to be customised for the particular soil type and ambient conditions.
The efficacy of the surface treatment is influenced by variables like traffic volume, moisture content, and soil makeup. Even under high traffic loads, engineers can design surfaces that are resistant to erosion, dust, and deformation by carefully choosing the correct chemical blend.

Gold Reef’s bespoke dust suppressants
After years of devoted research and development (R&D), Gold Reef has created a line of custom dust suppressants that are intended to work best in a variety of settings. These chemicals are deliberately designed to solve particular requirements and issues for miners, farmers and civil engineers. We can customise chemical formulas to fit each project’s unique soil types and environmental circumstances.
Gold Reef uses high-quality chemicals and advanced technology to formulate its dust suppressants. These products have a low environmental impact, improved surface stability, and excellent dust management. Furthermore, polymers like GR 1265 significantly reduce the carbon footprint associated with construction and maintenance by minimizing the need for traditional paving materials. They also enhance water permeability, reducing surface runoff and promoting groundwater recharge.
Gold Reef’s dedication to innovation goes beyond just creating new products. We work closely with clients to offer technical assistance and direction. Our clients are guaranteed the best outcomes and the most return on their investment thanks to this cooperative approach. Our emphasis on R&D also means that our chemical solutions are always changing to satisfy the industry’s shifting demands.
Water-based polymers offer a sustainable, cost-effective, and durable solution for stabilising eco roads and runways, supporting the global shift toward greener infrastructure while ensuring long-term performance and environmental preservation. Our chemicals are essential to the development of nationwide infrastructure projects that are safer, more effective, and more sustainable.
