Coursing bricks and coursing blocks

Coursing bricks and coursing blocks

Our coursing bricks/blocks have a reduced height of 65mm compared to a full-sized block, and are available as medium dense and lightweight options.

They are available in two sizes which are 100mm x 215mm x 65mm (Brick) and 140mm x440mm x 65mm (Block). Our coursing brick/blocks are low carbon as standard - up to a 50% carbon reduction compared with using OPC (Ordinary Portland Cement).

What are coursing bricks used for?

Coursing bricks are designed to maintain or make up heights in blockwork and for filling in around openings (for example, around pipe or ductwork), without the need to cut down a full-sized concrete block.

They are also used as kicker or joist height units to help achieve the correct wall height for block work and in beam and block flooring to maintain the floor’s height.

The bricks are typically used as an infill especially around windows and doors, and are used in conjunction with their respective full-sized blocks.

What are the advantages of coursing bricks?

The use of coursing blocks significantly reduces and, in most cases, eliminates the need to cut larger aggregate blocks down to size, which saves time, increases productivity and reduced waste.

As they have similar performance levels to their respective aggregate blocks (in terms of thermal properties, water absorption, density and shrinkage) the use of coursing bricks means that the overall wall construction can be considered to be the same. Their use also ensures a uniform thermal performance is achieved throughout the wall. Coursing bricks help to avoid differential material movement issues.

Good quality coursing bricks age harden.

What types of coursing bricks do CCP sell?

We offer two types of coursing bricks and in two sizes:

Medium dense Modulite coursing bricks

These are used in conjunction with our medium dense Modulite range of aggregate blocks.

Ultra-Lightweight coursing bricks

Our Lay-Lite lightweight coursing bricks are used alongside our Lay-Lite concrete blocks and are suitable for internal leaves above the damp-proof course.

For our ultra-lightweight Lay-Lite coursing bricks, the specially selected aggregates used in the manufacturing process provide density, strength and thermal conductivity values which are comparable with the majority of our lightweight aggregate blocks with a density range of 1000 – 1500kg/m3.

Lightweight coursing bricks require protection from long term freeze-thaw cycles. Lightweight bricks can be used on inner leaves and external walls when  protected from prolonged frost or snow by render.

What specifications are they available in?

The solid bricks/blocks are manufactured and tested according to BS EN 771-3: 2011.

Our Modulite coursing bricks / blocks are available in two sizes: 215mm x 65mm x100mm and 440mm x 65mm x 140mm (l x h x w)

Our Lay-Lite coursing brick is 215mm x 65mm x 100mm (l x h x w)

All three blocks have a compressive strength of 11 N/mm2
