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.

WHAT IS PREMIX CONCRETE?

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.  Concrete mix 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.

Concrete mix 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.
Quality

Both Premix concrete and Ready Mix concrete are high quality options however the Mastermix range of concrete mix 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 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.
