Complete flooring design freedom
Experience the enduring beauty of Terrazzo flooring on your next project
Terrazzo Flooring offers you the ultimate in durability and design versatility; from classic grey concrete through to fully exposed Terrazzo, marble, vibrant colour and decorative inlays. Perfect as a new floor or as a thin-set overlay to an existing concrete floor and starting at a thickness of only 10mm! Meaning no need to adjust set downs in the base slab or adjust door thresholds etc. Terrazzo Flooring can be used in a multitude of flooring applications and is suitable for pedestrian traffic in shopping centres, showrooms, restaurants, offices, shops and apartment buildings. Backed by one of the worlds most respected industrial companies Terrazzo Flooring is formulated using a self-levelling, ultra-fast setting cementitious system which is then either burnished or polished to form flat, smooth floors, perfect for retail, hospitality, commercial and residential applications. Available in a range of colours, and aggregates sizes we can tailor the final finish to suit you aesthetic
We have an extensive range of cementitious floor systems to suit your next commercial or residential project. From traditional terrazzo to the latest self levelling cast in-situ floor we can provide a full service from specification through to installation.

Traditional Cast in-situ Terrazzo - bonded or un-bonded
Considered by many to be the ultimate in long lasting seamless flooring, traditional Terrazzo cast in-situ floors are a composite of stone chip and Portland cement. Available in a huge number of finishes, inlays and effects available.
Sand Cushion Un-bonded
A cement matrix topping under-bed with wire reinforcing, isolation sheet, and sand layer system for interior floor use. This is the most enduring cement system.
Sand Cushion Bonded
A cement matrix and underbed system for interior and exterior areas where conditions require 30mm to 50mm inches of recessed depth to be filled in addition to the 10mm terrazzo topping.
A nominal 10mm think polymer modified cement matrix veneer placed upon a provided level concrete slab. Polymer provides strength to allow for thinner applications of cementitious systems.
Terrazzo flooring design considerations
We offer three main types of topping slab each with their own benefits and appropriateness for differing applications
- Sand cushion un-bonded. Typically 75mm thick with steel reinforcing over an isolation membrane
- Bonded. As above but bonded to the sub-base with an epoxy membrane
- Thin-set overlay. Nominally 10m thick.
Of the three options the thin-set polished concrete overlay is preferred in most applications for it’s superior design flexibility, workability, speed of installation and cost effectiveness. The thin set overlay material is an engineered cementitious overlay designed specifically for use as a polished concrete topping - contact us for your free guide specification and technical information. Recent local installations include Amano restaurant in Britomart, 125 Queen street food court (under construction) and a number of retail outlets in the CBD. Our Terrazzo flooring has also been specified for the Downtown City Rail Link. The optimum thickness for laying this type of floor is between 10-20mm depending on the size and type of aggregate. If the floor topping needs to be thicker than this then installing a specifically designed floor screed such in recommended and this can be installed either bonded or un-bonded.
Other Design Considerations Include...
- Colour / Aggregate: The this set overlay is available in white, light grey or grey and can be combined with a coloured oxide providing almost limitless colour options. Our preferred oxides are sourced locally from Peter Fell Ltd
- Control joints / divider strips: Saw cuts or control joints in the base slab must be mirrored through to the topping slab to mitigate any risk of cracks appearing in the topping slab. There are various designs and materials available which when properly treated can enhance the overall look at feel of the floor. Additional brass or aluminium can be added as decorative inlays, or to form graphic designs, logo’s etc. Any cuts, cracks or chases in the base slab need to be addressed and repaired prior to laying the floor. Typically concrete base slab is surveyed immediately after preparing the base slab to identify any remedial action required.
- Grinding / polishing and sealing: Once the floor has been installed to the manufacturers recommendations the topping slab can be ground and polished to achieve the desired look and feel - everything from a satin finish with little or no aggregate exposure (burnished effect) through to a high gloss with full aggregate exposure. The grinding and polishing sequence also determines the slip resistance qualities of the floor.
- Installation: After the sub-base is prepped and ready we can typically cast up to 150- 200m2 p/ day and the floor is walkable within 2-3 hours. Ideally the floor should be cast, ground and sealed prior to other finishing trades (skirting, painting, cabinetry etc) completing their work. The floor can then be protected until the project is ready for handover to the client.
- Lead times: We carry a limited stock of the product locally so for larger projects we recommend allowing up to 12 weeks for shipping.
- Cleaning and Maintenance: The topping slab is finished and sealed using a combination of a specially designed densifier and sealer which hardens and protects the surface. Cleaning and maintenance procedures and ongoing maintenance are available on request. For further detailed information please refer to the Guide specification.
- Pricing: Prices range from $235p/m2 for a simple 10mm overlay in a burnished effect through to $500+ p/m2 for a high end floor including screed, decorative inlays etc in a highly polished finish.

Concrete Jointing, Settlement and Crack Control
Concrete has been the standard flooring substrate in the commercial construction industry for many years. The concrete industry has developed many industry guidelines and recommendations to minimize cracking.
Cracks in concrete are a result of any number of issues, including volume change during the curing process, load deflection, settlement cracks and cracks induced from thermal stresses, which are typically due to non-climate controlled environments during the construction process. While shrinkage cracks, which account for most concrete cracking, become static once the volume change from curing is complete, any crack has the potential to become a dynamic, moving crack under thermal and load movement stresses.
