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.
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.
Standard UK bricks lay at ~60/m² in a single skin with 10mm joints. This lot (400 blocks) is best confirmed against your wall area plus a 8% cutting allowance.
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.
