Practical industrial storage solutions
EnviroInstall delivers Australia’s only complete block bunker and sliding roof system, combining a mass concrete block wall system, a retractable sliding roof and concrete pad into one coordinated package. You’ll deal with one team for the wall, the roof and the concrete pad without having to chase down three separate quotes.
Our integrated system improves site efficiency and protects valuable materials from the weather. It also provides a practical industrial storage solution for fertiliser on farms, aggregate at a transport depot, recyclables at industrial facilities and other bulk materials.
How it works
Every project starts with understanding your operation, the materials you’re storing and how your team needs access to them. This helps us plan a system that works for your site and the way you use it.
Site Assessment
We assess your site, the materials you’re storing, required storage volumes and any environmental or compliance requirements before recommending the right solution.
System Layout
Your block bunker and sliding roof system is configured specifically for your site, ensuring the layout, access and storage capacity suit the way you work.
Installation
Our experienced team installs the block bunker, concrete pad and sliding roof as one coordinated system, managing every stage from start to finish.
Handover
Once complete, you’ll have a weatherproof, purpose-built storage system that’s ready for immediate use.
Why a Block Bunker & Sliding Roof System?
