Why Our Path Topping Aggregates Are Different from Self Binding Gravel

When it comes to creating durable, aesthetically pleasing pathways, both Self Binding Gravel and Path Topping Aggregates offer excellent solutions. These products are particularly popular amongst customers who appreciate the natural look of gravel but require a firmer, more stable surface. However, understanding the differences between them is essential to ensure you choose the right material for your project. At Mainland Aggregates, we provide both Self Binding Gravel and Path Topping Aggregates, each with unique benefits and installation requirements. 


  
Self Binding Gravel 

Self Binding Gravel such as our Cotswold Self Binding Gravel is a versatile and hard-wearing product that has become a favourite for a variety of applications, particularly in stately homes, heritage properties, and woodland paths. It is graded from 10mm to dust, with fines being an essential component to ensure proper compaction. This characteristic makes Self Binding Gravel ideal for footpaths, bridleways, cycle paths, and golf courses. When installed correctly, it offers a smooth, firm finish that is both functional and visually appealing.  


  
Installation of Self Binding Gravel 

The key to the success of Self Binding Gravel lies in its installation. It must be laid on a firm sub-base of free-draining, granular material such as compacted MOT Type 3. The gravel should be applied to a compacted depth of no more than 50mm and should include a camber or cross-fall to ensure efficient water dispersion. Compaction is achieved in thin layers using a vibratory roller, with the final pass made with the vibration switched off. Water rolling is crucial during the final compaction to ensure a smooth, well-bonded finish. This involves spraying water directly onto the roller drum to prevent fines from sticking. 


  
Path Topping Aggregates 

Path Topping Aggregates, while similar in some respects to Self Binding Gravel, are distinctly different in their composition and use. These aggregates such as our York Cream Path Topping provide a firmer finish than standard gravels, making them ideal for paths, borders, and cycle tracks. The range of stone sizes in Path Toppings helps create a robust surface that still maintains a natural gravelly appearance. 

Installation of Path Topping Aggregates 

Like Self Binding Gravel, Path Topping Aggregates require careful installation to achieve the best results. They should be laid on a suitable free-draining, compacted sub-base such as MOT Type 3. A depth of 50mm is recommended for footpaths and borders. It is also essential to ensure that Path Toppings are laid with a camber or cross-fall to facilitate water dispersion, as poor drainage can lead to surface failure. The aggregates must not be laid when soaking wet or bone dry, as this can compromise compaction. Rolling with a vibrating roller in layers ensures a firm, stable surface. 


  
Key Differences 

While both of these decorative aggregates require a free-draining sub-base and proper compaction, the main differences lie in their composition and ideal applications. Self Binding Gravel contains fines that help it bind together when compacted, making it suitable for a wider range of applications including bridleways and golf courses. Path Topping Aggregates, on the other hand, offer a firmer surface ideal for footpaths and borders, but do not bind as tightly as Self Binding Gravel. 


  
Conclusion 

Choosing between Self Binding Gravel and Path Topping Aggregates depends on your specific project needs. If you require a durable, versatile material that can handle various applications, Self Binding Gravel is an excellent choice. For projects where a firmer surface is paramount while maintaining a natural look, Path Topping Aggregates are ideal.
