Leadtimes and delivery process
Most general products (natural kiwibricks) we stock at our Alexandra and Christchurch sites. We have relationships with many transport companies which allows for a full range of delivery services to your location. Leadtime is typically within 2 days of ordering.
For architectural products; coloured kiwibricks & secondary processing (honed, split, rumbled or textured products) we require a lead time of typically 6 weeks.
Manufacture: 2 weeks
Our plants are manufacturing to a two-week plan ensuring general stock levels are maintained.
Curing time: 1 – 2 weeks
Once manufactured concrete products require time to reach specific strengths. This time is variable depending on your block choice and final application.
Second Processing: 1 week
This process is done at site using an automated Hensel machine, involves a diamond cutting the face of the block. Our most popular finish for block, the result is a sleek aesthetic that highlights aggregate in the mix.
This process is done at our Alexandra site and requires extra curing time to ensure a strong product. The result is an exposed aggregate finish with a uniform texture across the block.
completed at site, blocks are tumbled down a cylinder to create a rough edge and weathered aesthetic.

Important things to consider when choosing kiwibricks
Every effort is made by Viblock to ensure the end user has a great product however we are only one step in the overall process. Each stage requires professional attention otherwise the result will not be to the desired standard.
Below outlines the stages in a block construction;
1. Select your desired product
There are many ways kiwibricks can be used to achieve a desired aesthetic. Key decisions include; the need for kiwibricks to be structural or a veneer, the laying pattern stack bonded or stretcher bond. From here what colour and finish you require can be decided. ViBlock offers the largest variety of manufactured kiwibricks finishes in New Zealand so will likely be able to accommodate your requirements. For further detail please refer to, Available Colours.
2. Ensure your designer is specifying to masonry standards
The build process is invariably smoother when wall sizes and controls are designed to specific lengths and details that work for blocks. There are many resources available to assist designers and architects, these include;
NZ design standard for masonry building not requiring specific engineering design – NZS 4229:2013
3. Engage a professional mason to lay the product
Block layers can make all the difference when building with masonry. Block layers have a trade association that provides them with support in training and ongoing learning this goes above the licenced building practitioners. Above the trade association block layers can become Master Masons. Contracting with a Master Mason ensures the individual has been assessed as having an appropriate level of skills and knowledge to complete work to an industry best practice standard. More information can be found at the following links
Or you can contact us. Attached are guidelines for block layers to follow when using architectural masonry, it is important the block layer is aware it will be used as finished product.
4. Sealing product
Viblock recommends all masonry is sealed to improve the look and durability of the product. Sealing is especially important for coloured masonry to reduce the likelihood of efflorescence and maintain the desired aesthetic over time. Viblock recommends Sto weathertight sealing systems are used for any walls open to the elements. For internal walls there are many sealers in the market it is important you have a professional installer complete the sealing and they follow the manufactures recommendations.
Viblock manufactures Villa Veneer products, these are a great way to achieve a weatherboard look while getting all the benefits of kiwibricks. More information can be found here
Efflorescence: What you need to know
Efflorescence is a naturally occurring phenomena associated with all Concrete products. The chemistry involved is complex, involving several factors over which neither the manufacturer, the contractor, nor the end user has total control.
At Viblock we are very much aware of efflorescence and the problems it can create. Our manufacturing processes have all but eliminated the occurrence of efflorescence in our products, however unfortunately, we have no control over the environment in which our kiwibricks & Pavers are used.
In order to reduce the chances of efflorescence occurring, it is important that purchases care for the products from delivery to sealing (refer Viblock Care of Kiwibricks, Pavers sheets and the paving laying guide).
Three steps to reduce the chance of efflorescence occurring
- Products must be stored correctly before laying.
- Laying of Blocks and pavers should be completed by a licensed trade professional.
- Sealing should also be carried out by a trade professional
Efflorescence should it occur in no way effects the structural integrity of our kiwibricks Blocks and Pavers.
