HOThis is what placing concrete in ICF actually looks like.
ICF needs a flowable mix — not dry, not sloppy.
That’s why typical ICF pours target 6–7” slump (150–175 mm) and are properly vibrated.
Why it matters:
• Concrete needs to flow around rebar and webs
• Vibration removes air pockets and honeycombing
• Proper consolidation = full wall strength
High slump doesn’t mean adding water.
It means using the right mix design and admixtures, then placing it correctly.
ICF pours fail when people treat them like flatwork.
They succeed when you respect the system.
