Contact sellerHow buying works

Condition grade 6/10 (B-grade). Assessed by the seller at listing; figures below relate to this specific lot of 40 sheets · 2440×1220.

About this lot

Surplus tongue-and-groove flooring from a cancelled order. Sealed pack, dry-stored under cover. Located in Cardiff — collection or arranged regional delivery available. Direct from Cardiff Urban Reclamation, a demolition operating out of Cardiff; live for 8 days.

This is exactly the kind of material that typically ends up in a skip costing the seller money; buying it diverts it back into a build. It is graded down on appearance alone; structurally and functionally it performs as A-grade.

Condition report & known defects

6/10
  • Cosmetic seconds — graded down for appearance, not performance.
  • Allow a cutting/waste margin of ~10% over a normal A-grade order.

Carbon & sustainability notes

This listing carries no CO₂-saved figure because the material is new; the sustainability win here is waste prevention — first-quality stock staying out of the waste stream entirely.

Reuse is the single fastest way to cut a build's embodied carbon — substitution beats offsetting every time.

Collection & delivery

  • Buyer collection in Cardiff; kerbside hand-load or forklift by arrangement.
  • Regional pallet delivery can be arranged from £90 depending on postcode and lead time.
  • Inspection before purchase is encouraged — bring a tape and check sample units against the measurements above.

Typical applications

  • Flooring, sarking and sheathing
  • Formwork, hoarding and site protection
  • Garden structures, raised beds and decking
  • Structural joists, rafters and studwork (graded stock)

Questions about this lot

Is this timber structurally graded?+

Where the listing states a grade (C16/C24) the stamp is on the timber. Reclaimed boards from Cardiff Urban Reclamation are sold for non-structural use unless re-graded by an inspector.

Will reclaimed boards have nails in them?+

The seller has metal-detected the stock; expect the odd missed fixing — budget 1 saw blades for a lot this size and check with a detector before machining.

How should I store it before use?+

Keep it stick-stacked, off the ground and under cover, and let it acclimatise on site for 7–14 days before fixing internally.
