About Envirocalc^®

Envirocalc is Envirocon's proprietary structural design tool for precast concrete block wall systems. It is cloud-based, free to use, and accessible anywhere. Delivering instant structural checks and design outputs fully aligned with Australian Standards (AS/NZS codes), Envirocalc lets engineers, designers and construction professionals assess retaining walls, bulk material storage and separation walls in real time, from any device, wherever they're working.

Every design can be exported as a comprehensive PDF design report, generated inside the tool and ready for submission, review or project records. There's nothing to install and nothing to pay. Envirocalc's intuitive design interface means fast, compliant, robust design outcomes.

Checks Performed

Envirocalc performs key structural verifications to ensure wall safety and performance, including:

Sliding Resistance
Overturning Stability
Bearing Pressure
Block Shear Capacity
Surcharge Load Impact
Internal Block Stability
Reinforcement Capacity

All checks are executed in line with AS 4678, AS 3600, and other relevant Australian design codes for precast and gravity retaining structures.

Design Reports

With one click, Envirocalc generates comprehensive PDF reports that include:

Project details and inputs
Wall layout and block configuration
Load and soil condition assumptions
Structural check summaries and outcomes
Compliance notes referencing relevant AS standards
Visuals and diagrams for clear presentation

These reports are ideal for sharing with engineers, project managers, clients, and local authorities as part of your submission package.
