Concrete blocks: buying guide for walls and fences

What is a concrete block and what is it used for?

The concrete block is a versatile building material for load-bearing walls, plot boundary walls and dividing partitions. It combines structural strength with finishes that can now be as refined as natural stone.

Smooth or rough (split) finish

The smooth finish, with its clean lines, is ideal for minimalist or industrial projects. The rough or "split" finish imitates the texture of natural stone and adds relief to exterior walls, blending well into gardens and rustic settings.

Available colours

There is no need to settle for builder's grey any more: there are blocks with integrated pigmentation in white, cream, anthracite grey or earth tones, which keep their colour stable against the sun and the passing of time without any need for paint.

Main advantages

High compressive strength and resistance to freeze-thaw cycles.
Good thermal and acoustic insulation thanks to its mass.
A wide range of formats, from thin partitions to retaining walls.
Fast installation thanks to its precise geometry.

Which block should you choose for your project?

For an exposed or decorative wall, the split finish is the best option; for a build where the block will be hidden behind a cladding, the standard smooth block is more economical.

Frequently asked questions

What is the difference between a smooth and a split concrete block?

The smooth block has clean lines and suits minimalist or industrial projects, while the split (rough) block imitates the texture of natural stone and adds relief to exterior walls.

Which concrete block is best for an exposed wall?

For an exposed or decorative wall, the split finish is the best option. If the block will be hidden behind a cladding, the standard smooth block is more economical.

Do coloured concrete blocks need painting?

No. There are blocks with integrated pigmentation in white, cream, anthracite grey or earth tones that keep their colour stable against the sun and the passing of time without any paint.
