Road Stabilisation
Products & Solutions
Poorly maintained roads can lead to costly damage and be a safety hazard to road users. In many cases, traditional methods of road stabilisation are simply not effective enough. RST Solutions develops and manufactures additives that are mixed with water and sprayed onto the road surface to provide a superior road stabilisation solution that will help maintain your unsealed roads in a safe and smooth condition.
RST Solutions’ Road Stabilisation Products
Road Stabilisation Products and Solutions from RST Solutions
We provide road stabilisation products that enhance the structural integrity, durability, and strength of unsealed and low-volume roads. Our additives create a stabilised road base, extending road life and helping to reduce costly repairs.
Our road–stabilising products bind soil particles together, creating a more compact and stable mass. This facilitates improved compaction levels and increased bearing capacity, resulting in stronger, more durable roads that can withstand heavy traffic loads. Using our products can also help with maintaining a smooth road surface, significantly minimising dust, road cracking, potholes, and other forms of road damage.
Road Construction and Stabilisation Applications we treat
Our soil stabilising additives can be applied to:
- Unsealed roads
- Car parks
- Hardstand areas
- Construction pads
- Foundations
- Airstrips
- Anywhere structurally compacted base materials are required
When applied to gravel roads, our products provide a longer–lasting, weatherproof road surface. Our products are applied during normal pavement construction and maintenance programs.
Material Types for Our Stabilisers: Choosing the Right Road Stabiliser Solution
The best road stabiliser for your project depends on traffic volume, environmental goals, weather conditions, and soil type. RST Solutions will recommend the most suitable additive. Our carefully formulated stabilisers are designed for a variety of materials, including:
- High plasticity material (fly ash, high clay content)
- Zero to low plasticity material (sandy, silty materials)
- Materials that are not compatible with water
The use of locally sourced materials with our additives helps reduce the need for importing aggregates, lowering transport fuel use and emissions, and minimising landfill. Our products offer a lower-impact alternative to traditional binders like cement and bitumen, supporting more sustainable road-making practices.
With proven application methods and over 30 years of experience in road stabilisation, we can provide effective solutions for your pavement challenges.
Product Application Equipment
Our soil stabilising aids are simply diluted in the compaction water and can be applied using water carts, spray nozzle systems, agricultural sprays or backpacks. We can also advise or custom–design spray systems to suit the application.

Road Stabilisation Solutions for the Environment and Safety
RST Solutions’ stabilisation products are designed to reduce environmental impact by utilising on-site materials, lowering waste, and minimising transportation. As alternatives to bitumen and cement, they can contribute to more cost-effective and environmentally conscious road construction.
Stabilised roads also last longer with fewer repairs, improving safety through reduced maintenance and a harder, smoother driving surface.

Frequently Asked Questions (FAQs)
Mechanical stabilisation improves soil strength by modifying its physical structure, such as adjusting particle gradation, compaction, or using geotextiles. Chemical stabilisation relies on additives that bind or react with soil particles to enhance strength, reduce plasticity, and improve water resistance
Yes, our road stabilisation solutions are environmentally friendly. RST Solutions strives, through a process of continuous improvement, to fully integrate health, safety, environmental and community (HSEC) consciousness into all aspects of its activities.
Stabilisation is ideally suited for low- to medium-volume roads, including rural roads, haul roads, airstrips, service roads, and hardstand areas. It can also strengthen the base of paved roads, helping to extend surface life and reducing maintenance.
Our additives are blended with compaction water and sprayed using standard water carts or application systems. We can recommend a solution that best suits your site equipment and soils.
Roads stabilised with RST Solutions’ products generally have a significantly longer lifespan than untreated roads, with extended surface life and fewer repairs when properly applied and maintained as part of an ongoing programme. Actual lifespan depends on factors such as correct application, soil type, traffic levels, and local climate conditions.
Our road stabiliser products are effective with a wide range of soil types, from high-plasticity clays to sandy or silty soils, including materials that poorly bond with water. Each site is assessed to recommend the best product for compaction, strength, and long-term durability.
