Why Choose Premix Concrete

Premix concrete solves the problem ready mix trucks create for smaller jobs. When you’re only pouring a few post holes or patching a section of path, booking a concrete truck with its 2-3 cubic metre minimum doesn’t make financial sense. You’d pay for concrete you don’t use and deal with the pressure of placing several cubic metres before it sets.
Our bagged premix gives you complete control. Mix only what you need for each stage of your project. If you’re setting fence posts over several weekends, you’re not racing against a truck full of concrete going hard in your driveway. Open a few bags, mix what you need, and save the rest for next time.
Quality stays consistent across your entire project. Every bag comes from the same batch with identical ratios of cement, sand, and aggregate. You won’t get colour variations or strength differences between different parts of your work. This matters when you’re building something that needs to match or when repairs need to blend with existing concrete.
No minimum orders means you buy exactly what your job requires. Need three bags for a letterbox base? Buy three bags. Planning ten post holes? We’ll calculate the exact quantity and deliver bulk bags to your property if you’re using twenty or more. You’re not stuck with excess materials or paying for concrete you’ll never use.
Newcastle’s DIY homeowners choose premix for the convenience and flexibility it offers their weekend projects.


Premix Concrete Applications
Common DIY Projects
Premix concrete handles the typical jobs Newcastle homeowners tackle themselves. Fence post holes and clothesline installations are the most common – you’re setting posts that need solid anchoring without the expense of a concrete truck. Letterbox bases, garden edging, and border work all suit bagged concrete perfectly. Small path repairs, minor slab patches, and step repairs get done without waste. Garden features like raised beds or decorative elements work well with premix when you’re building in stages.
Repair Work
Crack filling and patching becomes straightforward with premix – mix only what the repair needs. Small area resurfacing, post replacements, and retaining wall repairs don’t justify truck delivery. Broken slab sections, driveway edge repairs, and damaged concrete around your property get fixed economically with bagged concrete.
Small Construction Projects
Shed anchor points under ten posts, small garden walls, and planter boxes all suit premix concrete. Equipment pads for air conditioning units or water tanks, outdoor furniture bases, and basketball hoop installations work perfectly with bagged supply.
Bag Sizes and Coverage
Standard 20kg bags cover approximately 10 litres of concrete. The 25kg bags give slightly more coverage. Calculate roughly 1.5 bags per standard post hole, though we’ll help you work out exact quantities for your specific project.
Newcastle Considerations
Our premix suits Newcastle’s coastal conditions when mixed and cured properly. The humid climate makes correct mixing ratios critical – premix eliminates measuring errors. Sloping blocks where truck access gets difficult benefit from staged bag delivery. Store bags conveniently and work at your own pace across multiple weekends.

Mixing & Application Tips
Getting the consistency right makes the difference between concrete that performs properly and concrete that cracks or crumbles. Add water gradually to your premix – you can always add more but you can’t take it back out. Pour a bit, mix thoroughly, check the consistency, then add more water if needed. Mix in a wheelbarrow for small quantities or use a concrete mixer if you’re doing multiple batches.
The right consistency looks pourable but holds its shape. Too wet and you’ll get weak concrete that shrinks and cracks as it dries. Too dry and you won’t get proper compaction around your posts or in your repairs. Aim for a mix that flows off your shovel slowly and holds together without being soupy.
Work within your time window. Once you’ve mixed your concrete, you’ve got 30-45 minutes to get it placed and finished before it starts setting. Don’t mix more than you can use in that timeframe, especially on warm Newcastle days when concrete sets faster.
Curing matters as much as mixing. Keep your fresh concrete moist for at least seven days after pouring. In Newcastle’s climate, that means covering with damp hessian or plastic sheeting and rewetting daily. Concrete gains strength through proper curing, not just by drying out. Skip this step and you’ll get surface cracking and reduced strength.
Avoid pouring in extreme heat. Early morning or late afternoon works best during Newcastle summers. Hot concrete sets too fast and you’ll struggle to finish it properly before it hardens.
Bulk Bag Delivery
We deliver bulk premix bags straight to Newcastle properties when your project needs twenty bags or more. One delivery replaces multiple trips to the hardware store, saving you time and vehicle wear. Your bags arrive stacked on a pallet, stored conveniently wherever you nominate on your property.

Maitland properties and Hunter Valley locations receive bulk premix delivery for DIY projects. East Maitland, Rutherford, Thornton, and surrounding areas all fall within our delivery zone.

We know the area, we know the access challenges different suburbs present, and we know how to get your premix concrete delivered efficiently.
Frequently Asked Questions
Standard 300mm diameter post holes at 600mm deep need about 1.5 x 20kg bags each. Deeper holes or larger diameters require more. We calculate exact quantities when you tell us your post size, hole depth, and how many you’re setting.
Keep bags dry and off the ground. Concrete absorbs moisture through the bag and will set solid if left exposed to weather. Store in your garage or shed, or cover with waterproof tarps if outdoor storage is your only option. Properly stored bags last several months.
For projects under 1 cubic metre, premix bags cost less than ready mix truck minimums. Once you’re pouring 1.5+ cubic metres, ready mix becomes more economical. We’ll tell you honestly which option suits your project better.
You’ve got 30-45 minutes from adding water to getting it placed. Hot weather shortens this to 20-30 minutes. Mix only what you can use in one session.
Saturday delivery available for bulk orders. We arrange timing that suits your project schedule. Most Newcastle deliveries happen weekday mornings, but weekend service works for homeowners who need materials for Saturday projects.
