Building blocks that grow.

EXO™ living barrier blocks and ThinLine panels turn ordinary fences, walls and sound barriers into lush, carbon-absorbing green walls — engineered to sprout, fill in, and thrive.

🌿 Living green walls 🌍 Captures CO₂ 🧱 Bolt-on / drop-in 🔇 Cooling + sound dampening

From bare panel to living wall

Each EXO block ships ready to grow. Plant it, and it transforms — capturing carbon the whole way.

Why EXO

Carbon-negative infrastructure

Every wall becomes a carbon sink — CO₂ offset is tracked per block and rides into the Atlas vault for credit issuance.

Cooler, quieter spaces

Living facades shade buildings and dampen noise from roads and barriers.

Drop-in & modular

Standard sizes fit fences, sound walls and retaining structures — replace a single block, not the wall.

Built green

Builders submit each install to BrickTickler, where the captured CO₂ is recorded per block and forwarded into the Atlas vault — turning verified carbon offset into a tradable asset on the network.
