Yes. SuperSlab offers improved R-value and thermal mass, creating a warmer floor. SuperSlab+ enhances this further with a fully insulated or edge-insulated system that exceeds standard thermal requirements. 

Not usually. Shear keys aren’t required under CodeMark unless specific seismic conditions apply. In seismic zones (e.g., Christchurch), shear keys are still recommended unless soil conditions indicate lateral spreading; however, this will be determined by an engineering team in the design process.  

Yes, BRANZ appraisal No.964 (2017) acknowledges that a SuperSlab flooring system complies with the New Zealand building code. If a SED is required, PS1 and PS4 statements will be required when lodging a consent. 

What is a PS1? A Design Producer Statement. This is confirmation from an engineer that it is designed to the New Zealand Building Code. 

What is a PS4? A Construction Review Producer Statement. This is confirmation from an engineer that it has been constructed in accordance with the details shown on the consented documents relating to the PS1. 

Yes. When CodeMark conditions are met, councils must accept SuperSlab. All supporting calculations and drawings are provided by the slab designer and can be submitted with your initial building consent or as an amendment. 

If your site qualifies as ‘good ground’, engineering isn’t required under CodeMark. If an SED is needed, design generally takes 3-5 working days. 

SuperSlab includes rib structures that average around 125mm of flat concrete. However, this is offset by savings in: 

• Excavation and disposal 

• Hard fill requirements 

• Block perimeter foundations 

Yes. Experienced contractors can install a SuperSlab in approximately 3 days. Traditional footings typically take around 2 weeks, resulting in significant time and labour savings. 

Yes. SuperSlab works well on sloping sites. Minor steps can often be poured in a single pour. For more significant level changes, the retaining wall footing is integrated into the lower slab, reducing excavation. Stepped floors may require SED. 

The standard SuperSlab system is designed for 2.5 kPa (suitable for residential garage loads). With specific design input, the system can be upgraded to handle loads up to 10 kPa. Reinforcement and topping thickness may vary for heavier applications. 

Yes. SuperSlab can be used on sites with an allowable bearing pressure starting at 50 kPa (as per Table 1 in the SuperSlab Technical Manual). For other ground conditions, a Specific Engineering Design (SED) may be required. The system can also span between piles on poor ground or deep topsoil, making it suitable for a wide range of land classifications. 

Yes, any qualified builder can construct a SuperSlab foundation when following the supplied plans and construction specifications. 

SuperSlab is a fully engineered and compliant concrete foundation system. It offers time and cost savings, while enhancing energy efficiency and structural strength. SuperSlab is CodeMark certified and BRANZ appraised for peace of mind.

Consider the construction sequence, the overall project timeline, and where program requirements or specific finish types are necessary.

For example, foundations and substructures can typically have lower carbon footprints for their respective grade, whereas elements requiring a quick formwork turnaround e.g., precast elements, are more sensitive to carbon optimisation.

Yes and no. The curing time depends on several factors, with raw material availability being a key one.

In the South Island, achieving lower-carbon outcomes often requires cement substitutions. Depending on the time of year, these substitutions may slightly impact the initial setting time. In the North Island, this is less likely due to the availability of low-carbon cements.

Our Plant Engineers can optimise curing times based on your specific construction circumstances.

Yes, it can. We first assess the structural application and program performance before optimising the carbon footprint of your project. Allied Concrete provides expert guidance to ensure the best fit for each project.

Yes! Allie is always available to assist you, anytime.

Yes, using low-carbon concrete can help projects achieve Green Star, Homestar, and LEED certification points due to reduced embodied carbon.

Depending on the mix, CO₂ reductions of 20-80% can be achieved compared to standard concrete.

Properly designed low-carbon mixes offer comparable strength, durability, and workability to traditional concrete while reducing environmental impact.

Low-carbon concrete is designed to reduce carbon emissions by incorporating various methods, including the use of supplementary cementitious materials (SCMs), lower-carbon cement made in New Zealand, sustainable aggregate sourcing, and other initiatives. 

Yes, applying multiple coats of Ready sealer can enhance the protection and appearance of your concrete surface. Follow the product instructions for recommended drying times between coats to ensure optimal performance.

Ready Thinners are used to adjust the viscosity of sealers and other concrete treatments for easier application. These concrete thinners allow for smooth and even coverage, helping to achieve a professional finish.

We stand behind Ready Acid Wash as the best concrete acid wash in New Zealand. Its concentrated formula effectively removes stubborn stains, efflorescence and salts, preparing concrete surfaces for optimal sealer adhesion.

Applying Ready concrete sealers is straightforward. Here are the detailed steps:

1. Clean the concrete surface thoroughly to remove any dirt, oil or debris. Use a pressure washer for best results, and allow the surface to dry completely.
2. If using the sealer on new concrete, treat the surface with Ready Acid Wash, a popular concrete acid wash in New Zealand, to remove latence and salts. Follow the detailed instructions for applying acid wash.
3. Stir the sealer well before use to ensure an even consistency.
4. Use a roller or sprayer to apply the sealer evenly across the concrete surface. Apply in thin, even coats to avoid pooling and ensure thorough coverage.
5. Allow the first coat to dry completely, typically for 24 hours. Avoid foot traffic on the surface during this time.
6. Apply a second coat if necessary, following the same method. Allow it to dry completely.
7. Let the concrete sealer cure fully before exposing the surface to heavy traffic or harsh weather conditions. This can take up to 72 hours.

By following these steps, you will achieve a durable and long-lasting finish on your concrete surfaces.

Yes, Ready Products can be used on both new and old concrete surfaces. For old concrete, keep the surface clean and free of contaminants before applying the concrete sealer, acid wash or thinner to achieve the best results.

Decorative concrete is a type of concrete enhanced through various techniques to provide aesthetic appeal along with traditional functionality. Some of its benefits include:
Aesthetic versatility — Decorative concrete can mimic other materials like brick, natural stone or even wood, providing countless design options.
Durability — Like standard concrete, decorative variants are incredibly durable and suitable for high-traffic areas.
Low maintenance — Unlike natural wood or stone, decorative concrete requires minimal upkeep.
Cost-effectiveness — It is often more affordable than other paving or flooring options, especially for larger areas.
Customisation — Decorative concrete can be tailored to fit specific design needs and personal preferences.

The cost of decorative concrete depends on several factors, such as the complexity of the design, the types and quality of materials used and the scale of the project. Basic staining or simple stamping patterns are generally more affordable, while intricate designs and advanced textural effects may cost more.
