When a 300mm wall has to carry serious reinforcement - a tall core-filled retaining wall, an engineered structural wall, or a big pier - this is the block. The single large core gives you a clear 290mm-deep cell that will take a proper cage of steel and let the concrete flow right through without a web in the way. Because Adbri's coding and published weights point to a A heavier unit than the Litec equivalent on Adbri's published weights - rather than a Litec lightweight, it also delivers around 238kg per square metre of wall, which is why it's often specified for boundary and party walls where sound insulation matters.

Key Features

  • One large 290mm-deep core - takes a full reinforcement cage, not just a bar
  • Closed ends hold the grout without formwork
  • No intermediate web: concrete flows and consolidates cleanly
  • 300mm wide - for tall retaining walls and heavily loaded structural walls
  • Standard-weight dense: around 238 kg/m2 of wall, good acoustic mass
  • Pairs with the 30.45 clean out block in the bottom course
  • First-quality units only, no seconds
  • 60 per pallet, 53 per tonne

  • Dimensions: 390 x 290 x 190mm
