Engineering DESIGNS Made Simple
Designing with Interbloc and Stonebloc just got easier. EnviroCalc is a purpose-built software solution that ensures your retaining wall designs meet all NZBC requirements. Unlike generic engineering programs adapted for New Zealand, EnviroCalc is designed specifically for Interbloc and Stonebloc, simplifying complex calculations and generating accurate, compliant reports. Its intuitive interface and streamlined workflow make it easy to use, even for those new to retaining wall design. Focus on what matters most – building – with confidence, knowing your designs are sound and fully compliant.
EnviroCalc automates complex engineering calculations, ensuring your Interbloc and Stonebloc designs are NZBC-compliant in minutes—not hours.
Get accurate, council-ready results fast and focus on building with confidence.

Key Features of EnviroCalc
At Envirocon, we understand how time-consuming it is to get all the calculations right and collate them into a document. That’s why we bring you software that is:
- Effortless Creation & Calculation: Fast, intuitive design and calculation.
- Comprehensive Gravity Wall Support: Accurate for any gravity wall type.
- Layer-by-Layer Precision: Exact calculations for every layer.
- User-Friendly Interface: Easy for both experts and beginners.
- Developed by Experts: Built with engineering knowledge for reliable results.
The Man Behind the Software
Osama's nine-year career in civil engineering began as a technical field engineer, sparking a passion that led him to pursue a PhD at the University of Auckland. His research focused on sustainable concrete for gravity retaining structures. In 2021, Osama joined Envirocon, where his expertise in streamlining calculations proved invaluable. The idea for EnviroCalc emerged, and over the next year, Osama collaborated closely with the web development and UI/UX teams to bring the software to fruition. This accomplishment ran parallel to his doctoral studies, culminating in a thesis he will publish later this year.
