From Miami shorelines to the job site.

Every year, sargassum piles up on South Florida's beaches faster than anyone can clear it. We collect it before it rots, process it, and bind it into a proprietary cementitious matrix, swapping out a share of the carbon-heavy inputs conventional cement relies on.

The result has less embodied carbon than a standard bag of concrete mix, meaningfully, without sacrificing the strength or workability contractors expect. It started as material research for our own architecture studio; now it's available by the bag.

A waste-not approach to building material.

Need modular components fabricated for your next project? We can produce these for you. We create bricks, breeze blocks, seawall tiles, and custom modular components!

Developed by YEN Studio.

SargoX is developed by YEN Studio, a Miami based architecture studio working at the intersection of the built environment and material science. The studio designs with SargoX directly, using its own projects as pilot environments for the material.

The 50 lb bag is the same formulation the studio specifies for facades, blocks, and coastal pours, just packaged for your own site.
