Reclaimed Stone Flags
York stone and other sandstone flags lifted from mills, streets and yards, cleaned and re-laid. Thickness varies flag to flag and the wear pattern is a century old, which is the point of using them.
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.
York stone flagging, lifted and relaid continuously since the mills and streets it came from
Process
Feedstock
Reclaimed
Sandstone flags recovered from mill floors, pavements and yards; sorted and cleaned rather than re-cut
Process heat
No heat
Binder
No binder
Fabrication
Workshop-made
Sourcing: yard-dependent; northern stock is routinely hauled the length of the country
Who Builds It
Trained contractor
Established in the UK
Uneven thickness is the whole difficulty — each flag is bedded to its own depth, which is slower than laying calibrated stone and needs a mason who expects it
End Of Life
Demountable
Sand- or lime-bedded flags lift cleanly and go on again; cement-bedded flags do not
Maintenance: Re-bedded individually where they rock; the stone itself needs nothing
Specification Risk
What a specifier has to resolve before this can be built.
- Certification
- No BS EN 1341 declaration for reclaimed stock. Slip resistance is untested and varies with the wear it already carries
- Fire
- Non-combustible
- Warranty
- Supplier warranty on quantity and grade only
- Insurance
- Not normally an issue
- Supply
- Finite and non-repeatable. Secure the full area plus wastage in one lot — a matching second batch may not exist
Read This Honestly
- •No declaration is held for this stock. An EPD covering recovery, processing and transport is possible in principle for a reclamation supplier — Reclaimed Brick Company published one for reclaimed brick in 2025 — so this is evidence not yet held, not evidence that cannot exist.
- •Reclaimed does not mean local. Much of the York stone in circulation is hauled far from where it was lifted; ask the yard.
- •Worn flags are polished by use. For a wet or sloping external route, have slip resistance assessed rather than assumed.
Design & Specification Notes
York stone and other sandstone flags lifted from mills, streets and yards, cleaned and re-laid.
Material Note
Nothing is quarried and nothing is fired, so what remains is lifting, cleaning and haulage. Whether that is a low-impact choice turns almost entirely on how far the stone travelled.
Typical Uses
- •Primary flooring
- •High-traffic circulation
- •Work areas
Key Performance
Hard-wearing surface for high footfall.
Specification Actions
- •Establish the yard and the haulage distance — with no quarrying or firing, transport is what is left.
- •Confirm the thickness range before setting out; reclaimed flags vary flag to flag and the bedding depth has to absorb it.
- •Lay on a lime or sand bed rather than a cement screed so the flags can be lifted and used again.
Indicative Health & Indoor Air
Inert stone. Cutting and dressing release silica dust — a control for the mason.
