Renewabuild Academy
Learn to build our structural hempcrete
wall system.
A step-by-step video series covering every stage of installation — from the first string line to the final scratch coat — for builders, contractors, architects, and developers working with our block system.
Built to be learned,
not just delivered.
Our post-tensioned hempcrete block system replaces conventional framing, insulation, and drywall with a single structural assembly — which means the build sequence looks different from a typical wood-frame or CMU job. Renewabuild Academy walks your crew through each stage on camera, in the order you’ll actually encounter it on site.
Work through the series in order for a full walkthrough, or jump to the stage you need before your next pour, course, or inspection.
