Send us a questionConventional bricks are fired at 900°C, consuming fuel and emitting CO₂. Robricks eco bricks are cold-pressed: same minerals, triple the compressive strength, no kiln needed.
15 MPa compressive strength — three times the 5 MPa typical of conventional bricks. Suitable for load-bearing walls and one or two-story residential buildings.
Yes — it's one of our most popular uses. The Structural Brick handles high surface temperatures and delivers a natural rustic finish. Thousands of grills across Chile are built with Robricks.
Not for simple projects like garden walls or grills. For structural builds, we recommend technical supervision. Our free manual covers both scenarios.
Yes. The compression process creates dense, low-water-absorption units. They perform in dry and rainy climates alike, including areas with moderate frost.
We carry stock of all three models for small projects. For larger volumes, contact us at least 5 business days ahead to guarantee availability.

About Us
Made in Chile.
Made in Chile.
Built to be different.
Robricks was created to prove that building well and building clean are not opposites. We are Chile's eco brick — combining industrial strength with a minimal footprint.
Mission
Replace conventional brick with an alternative that lasts longer, pollutes less, and costs the same. No trade-offs.
Vision
To give every construction project in Chile the option to build without burning. One pressed brick at a time — until it becomes the standard.
