About this lot

Discontinued line — manufacturer no longer produces this thickness. Brand new, banded. Suits low-rise infill and partition work. Located in Cardiff — collection or arranged regional delivery available. Listed 4 days ago by Cardiff Urban Reclamation, a demolition based in Cardiff.

Every lot here was once destined for waste transfer — listing it instead keeps first-quality material in circulation at well below merchant list. B-grade pricing reflects cosmetics, not performance — the defect notes below set out exactly what was downgraded and why.

Condition report & known defects

7/10
  • Each unit inspected and photographed on request before dispatch.
  • Colour banding varies between firing batches — blend from 2 packs when laying.

Carbon & sustainability notes

No reuse CO₂ credit is claimed on this lot: it is unused stock, so the embodied carbon was committed at manufacture. Buying it still prevents waste — material sent to landfill or energy recovery delivers none of its embodied value.

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

Collection & delivery

  • Collection from the seller's Cardiff premises — forklift loading available weekdays 7:30am–4pm.
  • Regional pallet delivery can be arranged from £65 depending on postcode and lead time.
  • Inspection before purchase is encouraged — bring a tape and check sample units against the measurements above.

Typical applications

  • Garden and boundary walls
  • Below-DPC and footings (engineering grades)
  • Conservation infill and patch repairs
  • Feature interior exposed-brick walls

Questions about this lot

How many bricks do I need per square metre?+

Standard UK bricks lay at ~60/m² in a single skin with 10mm joints. This lot (1,200 blocks) is best confirmed against your wall area plus a 8% cutting allowance.

Are reclaimed bricks frost resistant?+

Bricks that have survived decades outdoors in Cardiff have effectively passed the longest freeze-thaw test there is. We still recommend F2-rated units for exposed copings and below-DPC work.

Can I get a sample before buying?+

Yes — the seller (Cardiff Urban Reclamation) will set aside sample units for inspection at the Cardiff yard before you commit to the full quantity.
