How does self binding gravel work? Self-Binding Gravel is an easy to lay alternative to traditional materials such as flags, paving, macadam or concrete. The gravel binds together when rolled to provide a self compacted surface which remains firmer underfoot than conventional loose aggregate.
What is self- binding gravel?
Self-binding gravel is one solution to this. Rather than being only made up of larger pieces of aggregate, self-binding gravel includes tiny particles that stick together when compressed. In many cases, self-binding gravel is rolled after it is laid to encourage cohesion between the fine dust, pebbles and other aggregate particles within it.
How do you add self binding gravel to a crusher?
On top of the crusherrun hardcore your Self Binding Gravel can be added. Make sure that about 2 to 3cm (1 inches) is above ground level. This will enable it to be compacted down with the vibrating roller but keep the final level where you want it.
Can I use self-binding gravel on a gradient?
As with other gravels, self-binding products are not suitable for use on any gradient greater than around 1:12, although the extent of migration experienced with self-binding gravels is considerably less than that found with loose gravels.
How low should I level my self binding gravel?
Where edgings are used, it's standard practice to keep the level of the self-binding gravel low by around 6mm or so to prevent migration of the material over the top of the edging. However, the surface must not be kept too low or a trip hazard may develop. 6mm is fine.

Does self binding gravel move?
As mentioned above, self-binding gravel is compressed when it is laid. In doing this, the aggregate is compacted together; however they are not bound together. This means that it can, and will, be moved around either by repeated footfall, or even following inclement weather.
Does self binding gravel need a sub-base?
The basic construction for our self-binding golden gravel is much the same as that for other path and driveway materials A free draining sub-base is essential, and this should be laid over prepared ground using a suitable membrane if ground conditions are poor.
Do you need a membrane under self binding gravel?
Construction and Coverage. The basic construction for any self-binding gravel pavement is the same as that for other gravels. A sub-base is essential, and this should be laid over a prepared sub-grade, with an optional separation membrane used between sub-grade and sub-base, if ground conditions warrant it.
What depth should self binding gravel be?
Dig out the area to approximately 15 to 20cm (6 to 8inches) deep. This allows room for at least 10cm (4 inches) of Crusherrun and 5 to 10cm (2 to 4 inches) of Self Binding Gravel. This is just a basic guide though, you can change these to suit your needs but we advise these as a minimum.

Why is gravel used in landscaping?
Gravel is a popular choice in decorative and landscaping applications, particularly to make paths. This is because it looks very natural and is sympathetic to the surrounding landscape. That being said, one of the biggest challenges faced by a gravel path is the constant displacement of aggregate. No matter where gravel footpaths or walkways are laid, it is almost guaranteed to move through continued use and will need constant attention to keep it looking tidy.
Is self binding gravel good for outdoor use?
In many applications, self-binding gravel is a practical, cost-effective and low maintenance choice for outdoor spaces. That being said, low maintenance does not mean no maintenance. Having been compressed, self-binding gravel is less likely to slip and slide around underfoot but it will become displaced after heavy use. For this reason, it will need to be smoothed and tended to over time to create the desired aesthetic appearance.

How deep should self binding gravel be spread?
Self Binding Gravels need to spread and compacted in thin layers. We recommend a finished compacted depth of no more than 50mm. Initially a 15-20mm layer should be spread using the back of a rake or screeding board. It is important the product is not spread using a tined rake as this will separate the coarse material from the fines and result in a patchy finish. Once the initial layer is spread it may be necessary to spray the material with water before rolling. If the product is too dry it will not compact. The amount of water added will vary depending on how damp the product is on arrival and the weather conditions. You will know if too much water has been added as the vibration from the roller will cause water to bubble up on the surface when compacting. The product should be compacted initially with the roller vibration turned on before the final passes are completed with no vibration.
Why do we use edging?
In most situations an edging would be used to separate a path from the surrounding landscape. Although not essential an edging helps with compaction of Self Binding Gravel as it prevents lateral movement of the material and also gives you a level to work to if laying material with the screed method. It is important that any edging used does not contain the sub base as this will restrict the sub bases ability to drain. Edgings are generally made from timber, concrete or block paviours.
Is self binding gravel prone to waterlogging?
The correct laying of Self Binding Gravel is critical to it’s performance. Incorrect laying will result in a loose surface, prone to waterlogging and rutting. Here we will explain how to lay Self Binding Gravel.
Can you spread a tined rake?

- There is a wide selection of these materials, but most of them tend to be 'local'. They are quarried and distributed over a local area and rarely travel more than 30 miles (50km) from source. They tend to be a cheap, easily obtained, soft-ish local stone with no other potential use, other than as a surface dressing for footpaths and low-speed trackways. So, in Northern England, they tend to b…

Pros and Cons
- Another great advantage of self-binding gravels is that it's immune to the disgusting habit of spitting out chewing gum. This filthy display of low manners has blighted the paving of every village, town and city in these islands, but the gum just cannot adhere to the loose, dusty surface of the gravels, and so it is soon lost, usually by sticking to the sole of some poor sod's shoes.
