Who this guide is for

- People comparing poured and precast terrazzo formats
- Anyone planning terrazzo floors, worktops or accents
- Renovators briefing a fabricator on chip and colour choices
- Planners weighing terrazzo against stone and composite
What terrazzo is
Terrazzo sets aggregate chips into a binder, then grinds and polishes the surface to reveal the speckled pattern. The chips can be marble, glass, quartz or other stone, and the binder can be cement-based or resin-based.
Because the look comes from the mix, terrazzo is one of the most customisable surfaces, ranging from soft and neutral to striking and colourful.
Poured versus precast formats
Poured terrazzo is formed in place and is specialist work, suited to seamless floors. Precast terrazzo comes as manufactured slabs or tiles, which can be more practical for worktops and smaller areas.
The format affects look, joints and how the surface is installed, so deciding between poured and precast early shapes the rest of the plan.
- Poured suits seamless floors and is specialist work
- Precast slabs and tiles suit worktops and smaller areas
- Format affects joints and seams
- Confirm the right format with a fabricator
Choosing chip size and colour
Small, dense chips read as a fine, almost stony texture, while large, sparse chips look bold and graphic. The base colour behind the chips sets the overall tone, from pale and calm to dark and dramatic.
Spend your planning energy here: chip scale, density, colour mix and base tone are what make one terrazzo feel restrained and another feel playful.
Where terrazzo suits a home
Terrazzo works as flooring, worktops, splashbacks and accent surfaces, and the same material can read very differently depending on application and finish.
As with any hard surface, match it to the room's traffic and conditions, and confirm weight, support and suitability with qualified professionals before committing.

Common mistakes to avoid
- Choosing terrazzo by name without planning chip and colour
- Assuming poured terrazzo is a quick or DIY surface
- Overlooking how chip scale changes the whole look
- Ignoring base colour, which sets the overall tone
- Forgetting weight and support considerations for the room
- Skipping fabricator advice on format and suitability
When to involve a professional
- A fabricator can advise on format, support and suitability
- Poured terrazzo is specialist work for qualified installers

Frequently asked questions
Questions readers ask about this topic
What is terrazzo made of?
Terrazzo sets chips of stone, glass or other aggregate into a binder, then grinds and polishes the surface to reveal the speckled pattern. The chips and binder can vary, which makes it highly customisable.
What's the difference between poured and precast terrazzo?
Poured terrazzo is formed in place and suits seamless floors as specialist work, while precast comes as slabs or tiles that can be more practical for worktops and smaller areas. The format affects joints and installation.
How do chip size and colour affect terrazzo?
Small dense chips read as a fine, stony texture while large sparse chips look bold and graphic, and the base colour sets the overall tone. Most of the planning lies in these choices.
Can terrazzo be used for countertops?
Yes; precast terrazzo in particular suits worktops, and the same material can also serve floors and splashbacks. Confirm weight, support and suitability with a fabricator for your specific layout.
