Hempcrete is a bio-based material made from hemp fibers, lime, and water that offers breathability, thermal performance, and sustainability benefits. In Playa del Carmen, Cancún, and Tulum, hempcrete is best used as a non-structural infill material within reinforced concrete construction, where it can improve comfort and environmental performance without compromising strength, durability, or hurricane resistance.

Hempcrete is often called carbon-negative because hemp absorbs CO₂ while
growing, while concrete and steel — extremely durable — take significant energy to
manufacture.

(Owen Geiger), The Mud Home and Build With Rise all work in earth-based and
alternative construction methods.

That’s the appeal: cutting waste from seaweed piling up on Caribbean
beaches while producing a lightweight, non-structural building material with
potential insulation benefits

Sargassum bricks blend dried, processed seaweed fiber with a lime, clay or
cement binder: collected, cleaned, dried, shredded, mixed, pressed into molds and
cured into lightweight blocks
