What concrete mix do I need?

That depends on what sort of job you’re doing. Different mix specifications are used for different purposes with higher-grade (strength) mixes being used for foundations as compared to slabs and walkways.
Council will quite often have recommended/required strengths suitable for local soil conditions so contact the Building Department for advice or check their website before commencing the work.

If you are unsure of your requirements, please contact us directly where we will be happy to advise you on the best option for your needs.
