Selecting the right premix concrete product to suit your project’s specific requirements can be difficult which is why MasterMix is here to save you time and money by walking you through the selection process.

  • This field is for validation purposes and should be left unchanged.

There are several ways to source the concrete needed for your next project. Concrete can be produced offsite before being delivered via a concrete mixer truck, which is known as Ready Mix concrete or bagged concrete can be mixed on site by adding water, which is known as Premix Concrete. Ready mix concrete NZ is produced using specialist mixing equipment which is normally not available at a construction site. Ready mix simply refers to the concrete being transported to the site ready for use.

Premixed concrete, like the products produced by Mastermix, are specifically crafted in our manufacturing plant with a proprietary blend aggregates, cement, paste and our very own special sauce, basalt fibre reinforcement for class leading concrete strength.

While both options are viable for your next project, our extensive range of premix options ensure we have the perfect solution every time.

Here are some of the factors you should consider when choosing between Premix Concrete and Ready Mix.

Time Commitment
Our premix range is designed to be mixed on site without any speciality equipment. Simply add the required amount of water, mix thoroughly and you are ready to go. You get to choose when you start the process which means more flexibility should there be any delays. This is a big benefit over ready mix options which require planning with a 3rd party provider for delivery at a specific time and place.
Both Premix concrete and Ready Mix concrete are high quality options however the Mastermix range of concrete mix ratio products offers a unique blend produced right here in New Zealand specifically formulated for our difficult weather conditions. Our specialist products have unparalleled strength at different set times to match your projects needs.
Speed Of Construction

Ready mix concrete NZ is mixed offsite which can help speed up the process assuming there are no delays in delivery or with the project itself. Our Premix range only requires adding water and can be batch mixed quickly on site to cater for the exact requirements of the job. No one is in a better position to know when the right time to kick off the mixing process is then the builder on mastermix. Mix the exact amount required, with no wastage every time with our range of Premix concrete products.

How To Make Premix Concrete

Our extensive range of concrete mix design NZ products come in 20kg and 30kg weatherproof bags which have a shelf life of 3 months. To prepare the ideal concrete for your next project simply mix 4.5L of water evenly through a 30kg bag of our Premix concrete.

Once the mixture has achieved a smooth workable consistency you are ready to pour your concrete. Wait 15 minutes after pouring, before you complete your final trowelling for the perfect finish.

It is important to remember not to pour the water and concrete separately into its final resting place as this may compromise the integrity of the project.

Before mixing our concrete products we recommend calculating the exact requirements of your project so that there is no wastage. 1 bag of our popular RTU and RTU45 products yields approx 0.018mɜ in an area of 1.00m x 450mm x 40mm.

Premix Concrete Price

Why Choose Mastermix Concrete Mix NZ?

Mastermix is an industry leader which is uniquely focused on providing concrete solutions for New Zealand’s toughest environmental and industrial challenges. We have been solving our customers concrete problems for over 20 years. We are so committed to finding the perfect solution that we pay independent laboratories OPUS and IANZ to test all our products before we offer them to our clients.

Mastermix Premix Concrete RTU
Mastermix RTU is our Premix Concrete offering specifically formulated for commercial and private projects which require high compression strength with a beautiful finish. This product is appropriate for original construction and repair projects.
Our Ready To Use concrete is conveniently packaged in 20kg and 30kg bags making it ideal for projects ranging from small post laying jobs to large scale building projects:
As part of commitment to our customers we have commissioned independent testing from the internationally recognised laboratory OPUS to verify the performance of RTU. Test results show results of better than 20Mpa after 7 days, with over 30Mpa reached after 28 days. Further, RTU is verified to meet and exceed NZ Standards: 3109 Concrete Construction and 3101:2006 Concrete Structures.
RTU45 Premix 45 min Concrete Premix
If you require a Premix concrete solution which still gives you time to work the finished product while building strength after just 45 minutes our RTU45 product is right for you. This concrete mix is reinforced with basalt fibre to give it the extra strength needed to withstand the toughest conditions.
Even though our RTU45 product sets much faster than our standard RTU product you can still expect the same level of performance offered by the latter:
As with all our products we wanted to get independent testing to ensure that our RTU45 product performed as advertised. OPUS Laboratory conducted the tests and proved that the product achieved the same 20Mpa after 7 days and 30Mpa after 28 days as our standard RTU Premix concrete.
RTU15 Premix Concrete Mix
Certain jobs call for extreme early strength which is why we developed our fast drying RTU15 Premix concrete. Despite offering early set times our solution still offers the same performance attributes as our standard RTU Premix concrete product.
In fact, due to how quickly our RTU15 premix concrete bag solution hardens, the product must be quickly mixed evenly before pouring into a pre-dug hole to prevent it from hardening before use. As such, it is only suitable for specific project which do not require a smooth trowel finish:
When developing our quick setting RTU15 concrete formula our intention was to maintain the same class leading compressive strength as the entire premix range. We called upon OPUS Laboratory to perform the same tests as those done for the other products. They reported that we had achieved our aim across the board so you can have confidence that RTU15 will set much quicker than our RTU product but last just as long in the real world.
