Introduction to Self Binding Gravel

Overview

Self binding gravel is a natural form of surface composed of different sized gravel, fines and occasionally a binding agent. Due to its composition, it is a cost-effective and very DIY friendly type of material. It is a very popular material for use in outdoor settings ranging from pathways through to bridleways, with some types such as Breedon gravel gaining the Royal assent and adorning heritage areas.

There are many types and applications for self binding gravel, and in this article we take a detailed look at these issues along with many others related in order to help you to decide whether it is right for your project and what the best options are for your needs. We certainly hope we are Breedon the next generation of British DIY landscape gardeners. Let's roll!

Key Takeaways

What is Self-Binding Gravel Made of?

Imagine a serene garden path or a rustic driveway where the gravel beneath your feet remains compact and neatly in place, complementing the natural surroundings. This is the essence of self-binding gravel. Distinct from traditional gravel loose stones, self-binding gravel contains a significant amount of fines — tiny particles that act as a binder when compressed. This creates a stable, permeable surface and fairly low-maintenance option for walkways and driveways. It's the fines that differentiate self-binding gravel, ensuring a firm footing and reducing upkeep hassles, making it less prone to displacement and blending seamlessly with natural landscapes.

How Does Self Binding Gravel Work?

Understanding the makeup of self-binding gravel is key to appreciating its value in landscaping. This versatile construction ingredient is a mix of gravel, sand, clay, and a significant amount of fines (dust). When compacted, these elements interlock, creating a stable and semi-permeable surface distinct from traditional gravel. The fines are crucial as a binder, supporting the larger particles and allowing water permeation, thus mitigating water runoff and erosion.

Making the Right Choice

Whether your selecting a self binding path gravel, or a self binding gravel for driveways, picking a suitable type always involves considering the intended use, aesthetics, local availability and drainage requirements. Each type offers unique characteristics, so choose one that aligns with your project's specific needs and style. We have detailed insights and specifications about Hoggin self binding gravel and Breedon gravel. If you have any doubts, consultation with local suppliers based on regional climate and soil conditions is recommended.

Colours

Self-binding gravel comes in a range of colours, from silver and grey to buff, gold and even red. Here is a list of the most available colours, which can be found in some of the popular brands mentioned or also as generic, locally manufactured materials.

Next, we cover the most common applications suitable for self-biding gravel.

Applications

Self-binding gravel has a broad range of uses, from residential driveways to rural walkways, as it is a cost-effective and reasonably durable surface. A self binding gravel pathway offers a firm, permeable surface suitable for pedestrian use. However, a self-binding gravel driveway is not as durable as others, such as loose-fill stone chippings for driveways, so it's best suited to light vehicular traffic. 

In gardens, it can be used for creating patios, borders and outdoor seating areas. The gravel is low maintenance, with the natural look favoured in commercial landscapes like golf courses, woodland paths and for bridleways, offering a solid and budget-friendly surface for equestrian activities. Self binding Breedon gravel has the royal seal and is widely used for heritage sites.

Exploring the Varieties

The variety of products is often influenced by local geology, giving each type a unique regional identity and low carbon footprint. In the UK, for example, limestone-based grey self binding gravel is common in the North, while in Scotland Old Red Sandstone-based options are more common.

Renowned types include Hoggin and Breedon Gravel, a crushed magnesian limestone from Derbyshire, noted for its 'Golden Amber' hue and often used in royal estates for its regal appearance. These gravels offer not just diverse colours and textures but also varying degrees of compactness and longevity, making the selection as much about function as form. Another popular choice is 'Cedec,' a durable and cost-effective selection valued for its versatility and availability through the CED group. 

Hoggin vs Self Binding Gravel

Hoggin is a natural blend of gravel, sand, and clay without any added binding agents, offering a traditional, more rustic surface that can become muddy in the wet. By contrast, self-binding gravel can include binders or additional fines (dust particles) which, when compacted, create a firmer, more stable surface that's less prone to shifting and better suited for wet conditions and drainage.

Although it is by no means an exhaustive list, here are a selection of the self-binding gravel products available in the UK:

How To Lay Self Binding Gravel

Laying self binding gravel paths is easily within the scope of DIY. The process involves preparing a solid base, typically a compacted sub-base, and spreading the gravel in layers, each compacted using a roller or vibrating plate compactor. This approach assures the surface is smooth and firm. Laying self-binding gravel on impermeable surfaces can interfere with the binder and lead to water drainage issues and inadequate binding, leading to our next section.

Can You Lay Self-Binding Gravel Over Tarmac or Concrete?

Laying self-binding gravel over tarmac or on concrete is not generally recommended, as water drainage is crucial, plus it may lead to insufficient binding of the gravel. For optimal results, it should be applied over a compacted sub-base to ensure proper binding and permeability.

Self Binding Gravel Pros and Cons

While self-binding gravel offers low maintenance, cost-effectiveness and a natural appearance, it's not without its drawbacks. It's less suited for high-traffic or steep areas and can become uneven or damaged after heavy use or in very wet conditions. It is not weed-resistant, so a weed membrane should be strongly considered.

How Much Self-binding Gravel do I Need for a Project?

When planning any landscaping project, determining the right quantity of materials can have a significant influence on the outcome. Consider the project area and desired coverage depth, typically around 50mm (about 2 inches). Generally, using a self binding gravel calculator is an elegant and simple way estimate the required amount based on your project's dimensions. It's usually wise to err on the side of getting a bit extra rather than facing a shortfall mid-project, which can end up costing a lot more.

Summary

Whether you're creating a pathway, a bridleway, or a outdoor living space for gatherings, self-binding gravel is a versatile, eco-friendly option for landscaping. For self binding gravel drives, understanding the properties, types and limitations will help you to make the right choice for your construction project. Remember to calculate your needs accurately, choose a type that best suits your project's requirements and always consult local experts if you have any doubts. Now, don't be Hoggin the computer, and get ready to renovate your outdoor space!
