Choosing the Right Screw or Fixing

Specifying Below and Above DPC: Get the Structure Right First Time

Structural performance starts with the right brick on the right course.

Solid engineering bricks below DPC deliver the compressive strength and low water absorption needed to resist frost and moisture, so movement and spalling don’t appear later.

That behaviour is proven by dense manufacture and Class A/B ratings, which maintain integrity in foundations and retaining walls where loads and damp meet.

Once you’re above DPC, facing bricks carry the visual brief while the engineered base does the heavy lifting – a clear separation of roles that keeps defects off the snag list. 

Tie the system together with the correct mortar, DPC and wall ties and you get a wall that performs to spec and stays that way through winter cycles.

Colour Consistency and Handling Speed: Why LBC and Perforated Matter

Finishes fail when batches vary or lifts slow the bricklayer.

LBC bricks solve the first problem with predictable colour and sizing, so elevations read cleanly across long runs and extensions. Perforated bricks tackle the second by reducing unit weight and improving mortar key, which helps teams keep a steady rate without compromising bond.

Your construction site will immediately see straighter lines, tighter joints and fewer rejected courses, proving material choice affects both appearance and productivity.

Order by the pallet and pair with the right sand/cement to keep tone uniform and bed strength consistent from the first course to the last.
