20+ years of expertise making Certus the trusted name in concrete flooring design, inspection, and compliance.
Certus specialises in commercial concrete flooring – offering design, inspection, surveying, compliance, and certification tailored to your project needs.
We work with asset owners, engineers, builders and sub-contractors and can get involved as early as ECI to ensure solid designs and well-defined flooring specifications are available for tendering.
Services
At Certus Consulting, we provide end-to-end expertise in concrete flooring design, testing and certification – ensuring every slab performs as intended, meets compliance requirements, and delivers lasting value.
-
With expertise in large-pour, low-carbon slabs, we design and deliver robust, cost-effective floors. Utilising mesh, steel fibres, Combi Slab, PT+fibres or PT.
-
We survey on-grade and suspended slabs referencing; CNZ Technical Specification 01:2021, TR34, ASTM E1155, EN 15620 and more. Using Precise Digital Levels, Axiom Pro and advanced scanning. Covering, FM, DM to verify tolerances for warehouses, G2P, ASRS, and high-bay systems.
-
We test concrete performance where it matters – on site. Using the eyeD device for real-time SFRC fibre checks, abrasion & slip testing, reinforcement pull tests and concrete cored strength tests. We deliver independent QA that ensures slabs perform as designed – no assumptions, no surprises.
-
Not every project needs a full design – sometimes it’s about clear, unbiased answers or working through a tricky issue. Our consultancy offers peer reviews, value engineering, specs, problem-solving, and training – independent, practical input when and where you need it.
-
Sustainability is built into every project – our value lies in taking a practical, design-led approach that meet Green Star and NZ guidelines – delivering floors that hit sustainability targets without sacrificing strength, compliance, or cost.
-
SFRC performance starts with the mix – proven through EN 14651 beam tests and verified QA. Confidence in residual strength fR1 and fR4 values, we help you base designs on real-world data, ensuring reliable, sustainable results even with low-carbon SCM blends.
-
Our SFRC and PT expertise extends beyond floors – from water-retaining structures and rafts to suspended slabs, tunnel linings, and precast elements – all designed to international and local standards for efficient, compliant, and buildable results.
Our Work
We combine technical precision, real-world experience, and industry leadership across projects of every scale — distribution centres, manufacturing facilities, container pavements, retail environments, and high-tolerance automation floors.
Operating where design, construction, and long-term performance meet, our team ensures your concrete floor does exactly what it’s meant to, well into the future. From bespoke slab designs to on-site QA and compliance assessments, we’re driven by the same principles: certainty, durability, and performance.
