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.
Renewabuild Academy
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.
The lessons
The build, stage by stage.
Twelve lessons, from layout to finish coat. Each links out to the full video.
String Line & Dry Fit
Setting your line and dry-fitting the first course before anything is set permanently.
Anchoring the starter strip
Fixing the starter strip that locates and anchors the entire wall above it.
Setting the tensioning rods
Placing the post-tensioning rods that give the wall its structural integrity.
Mixing the mortar
Getting the mix and consistency right before you lay a single block.
Laying the first row
Why the first course matters more than any other and how to get it square.
Building the second row
Picking up pace and rhythm once your first course is locked in.
Coupling the tension rods
Extending your rods cleanly as the wall gains height.
Adding the second rod row
Layering in additional tensioning as the assembly builds up.
Setting an electrical box
Coordinating rough-in electrical work within the block assembly.
Fixing a mistake mid-wall
What to do when a block goes in wrong – without tearing down your progress.
Applying the scratch coat
The first finish layer that preps the wall for its final surface.
Framing a window opening
Working openings into the block layout without compromising the wall.
