Hoggin / Self-Binding Gravel
Graded gravel with a natural clay and fines content that knits together when rolled damp. A firm, permeable, unbound path surface with no resin, cement or edging dependency.
Carbon and evidence
How This Is Made
An Environmental Product Declaration is issued by a manufacturer against a declared unit. This record has neither, so it states sourced facts about process and provenance instead of a carbon figure.
Traditional estate and park path surfacing; regional quarry names (Breedon, Cedec and similar) denote grades

Who Builds It
General trade
Established in the UK
Laid damp and rolled in layers; compaction quality determines whether it binds at all
End Of Life
Separable
Lifted and reused or spread; no bonded layer to break out
Maintenance: Topped up and re-rolled; weeds are the recurring maintenance item
Specification Risk
What a specifier has to resolve before this can be built.
- Certification
- No product certification; specified by quarry grade
- Fire
- Non-combustible
- Warranty
- None — a graded aggregate, not a system
- Insurance
- Not applicable
- Supply
- Widely available, though named grades are quarry-specific
Read This Honestly
- •Not resin-bound gravel. That is a manufactured system with a polymer binder and a published EPD.
- •Accessibility and wheeled-traffic performance are weaker than a bound surface — check the route requirement.
Design & Specification Notes
Graded gravel with a natural clay and fines content that knits together when rolled damp.
Material Note
Quarried, screened and rolled — no binder is added and nothing is fired, so the impact is extraction and haulage. Distinct from resin-bound gravel, which is a manufactured system with a polymer binder and an EPD.
Typical Uses
- •Planting systems
- •Biodiversity zones
- •Outdoor amenity
Key Performance
Supports biodiversity and surface water management.
Specification Actions
- •Confirm the quarry and haulage distance — with no binder, transport is essentially the whole footprint.
- •Confirm it meets the accessibility requirement for the route before specifying — an unbound surface is not always compliant.
- •Allow for periodic topping up and re-rolling rather than replacement.
Indicative Health & Indoor Air
Inert quarried aggregate, no binder.
