Why Variation Makes Concrete Bricks Beautiful
There’s No Such Thing as a Perfect Brick – And That’s the Point
When people picture brickwork, they often imagine uniformity: row after row of perfectly identical units, smooth and predictable. In reality, concrete brick beauty comes from natural variation. Subtle differences in colour, tone, and texture are not flaws — they’re what give a brick wall its warmth, depth, and character.
At Viblock, our bricks are crafted from natural aggregates, shaped with care, and handled by real people on real building sites. That’s why no two walls are ever identical, and why every project carries its own timeless appeal.

Every Viblock brick starts with aggregate sourced from Central Otago, a by-product of the region’s historic gold mining and dam construction days. This material is rich in colour and texture, and because it’s natural, it doesn’t behave like synthetic paint or plaster.
The composition of these aggregates gives each batch of bricks its own subtle fingerprint. Under sunlight, tiny flecks of mineral catch the light in different ways. On overcast days, the tones soften into a calmer, more muted palette.
Just like the grain of timber or the veining of stone, this variation is what separates a living, breathing material from something flat and factory-perfect. It’s why architects, builders, and homeowners who care about design often choose concrete bricks – they’re timeless, enduring, and expressive. This is the foundation of concrete brick beauty — every batch carries natural variation that creates depth and uniqueness.
Prefer a more uniform look? Our white and cream ranges use finer aggregates with a more consistent profile. They cost a little more due to the raw materials, but they deliver a beautifully refined appearance for those who want tighter control over colour.

What You’re Really Buying: Natural Aggregate
When it comes to the final look of your brick wall, mortar colour can make as much of a difference as the brick itself. Mortar choice can enhance or soften the effect of natural variation, changing how concrete brick beauty comes through in the finished wall.
A darker mortar can make the bricks feel richer and more defined. A lighter mortar can soften the look, letting the wall blend more seamlessly with other cladding materials. Here’s what you need to know:
- Season matters. In winter, mortar dries more slowly. That means you may see deeper colour variation across the mortar in the wall.
- Consistency matters. Site-mixed mortar is cost-effective, but it’s also riskier. Colour may vary from batch to batch
- Our recommendation: Opt for bagged mortar. It costs a bit more, but it removes most of the risks. You’ll get consistency, strength, and a cleaner final look.
