"If it's dry stacked, how does it stay together?" 🤔🧱
We get asked this all the time! People see us stacking Ecobrix ICF blocks like giant Lego bricks without a single drop of mortar and wonder what keeps the walls from blowing over.
Here is how the magic happens:
🧩 Interlocking Precision: The interlocking profiles on either side of each woodcrete block naturally guide them into place, creating a solid, uniform stack that stays perfectly aligned as you build upward.
🏋️ The Concrete Core: Once the blocks are stacked, we pour structural concrete straight down into the hollow cavities inside the wall.
💎 The Result: The woodcrete blocks act as a permanent, ultra-insulated stay-in-place formwork. Once the concrete cures, you are left with a monolithic, concrete core that is fully breathable.
No mortar to wash away in the rain, no specialized bricklayers needed—just a fast, bulletproof interlocking system that creates an incredibly warm and solid home.
