Vee Blocks

All blocks measure 610mm square in cross section but vary in length. B1 blocks are the standard type of block and are identified by having a V-shaped groove (female) on the bottom and one end of the block, and V-shaped projections (male) on the top and opposite end of the block. The direction of build is the direction in which the male projections should be pointing when assembling the wall.

B2 blocks are identical to B1 blocks with the exception that the male projection on the end of the block has been removed leaving a flat surface. The blocks are used to butt up to blocks which are at 90 degrees to the direction of build. They are also used at the end of walls to produce a smooth finish to the wall.

C1 and C2 blocks (combination blocks) interlock courses at corners. As well as having the usual groove in the bottom of the block, combis have transverse grooves running across the width of the block. This is designed to lock the blocks in the course below. C1 blocks, (as with B1 blocks), have the male V projection on the end of the block. C2 blocks have a flat male end as with B2 blocks.

T2 blocks are specifically designed for the formation of intermediate bay walls. These blocks have a flat male face.

Lifting point is by means of a 16mm inverted re-bar cast in during manufacture with hook using lifting chains or similar certified to Loler 1998.

Prior to lifting check the lifting point for wear or corrosion and check the block for cracks.
