Short answer: if you will make blocks and single-layer pavers only, choose BLOCKMASTER; if you also want double-layer (coloured face) paving blocks, choose CBM. Both series make the same block sizes at the same output: BLOCKMASTER 4 and CBM 12, BLOCKMASTER 8 and CBM 20, BLOCKMASTER 10 and CBM 25 are pairs with the same capacity. The difference is the second hopper on the CBM.
The one difference: a second hopper
BLOCKMASTER machines have one concrete hopper. CBM machines have a second hopper next to the main one. It lays a thin, coloured, smooth face mix on top of each paving block, so the machine makes double-layer pavers: the bottom layer carries the strength, the top layer gives the colour and the wear resistance.

Block sizes are 400×200 mm faces with 200, 150 and 100 mm widths. Daily figures are at full capacity in one shift; by changing the mould the same machine makes hollow and solid blocks, kerbstones and pavers.
Which one should you choose?
- BLOCKMASTER: when your market wants mostly blocks and plain single-layer pavers are enough, as in most of Sub-Saharan Africa. It is the simplest way to start a block business.
- CBM: in markets where buyers expect double-layer, coloured pavers, such as Morocco, Algeria and the Balkans, or when you want to supply pavers for municipal, housing and car-park projects and earn from pavers as well as blocks.
What both series share
- Every machine is test-run in our factory before shipping; production takes 45 days on average.
- Installation and operator training are included in the price; 2-year warranty; spare parts shipped the same day.
- One machine makes blocks, kerbstones and pavers by changing the mould.
We explain how double-layer pavers are made (face mix, pigment, machine choice) in our double-layer paver guide. Tell us which products and how many pieces a day you want to make on WhatsApp, and we will send the right model and the price the same day.
