Surf Block Maui—an offshoot of Hawai‘i Off Grid Architecture, upcycles foam scraps from local surfboard shapers into insulated composite concrete form (ICCF) blocks. Made of about 85% recycled EPS foam bonded with cement, these modular blocks require one-third less concrete than traditional cinder blocks and offer double the insulation performance. They’re fire-resistant, termite-proof, mold-resistant, and four times stronger than wooden walls in hurricanes.
Founder David Sellers discovered untapped potential when he observed dumpsters filled with polystyrene foam from surfboard manufacturers. His team secured a grant, developed pilot blocks, and is now constructing resilient, low-carbon homes—including one nearing completion in Olowalu. With local supply and low embodied carbon, Surf Blocks directly address both environmental waste and construction needs.
