It's a process similar to ancient adobe brickwork.
Mechanical engineers hope homes built with these mud blocks would replace traditional wood and stucco that can't withstand the heat of a wildfire.
UC Davis researchers tested the blocks in a furnace for seven hours at more than 2,000 degrees and the brick doesn't burn up.
Researchers put a blow torch to a block of wood and a mud block, comparing the differences.
They also say materials are cheap and sustainable because you can use locally sourced dirt to create the mud and press the bricks at the job site.
Take a look at the latest stories and videos about wildfires here in Central California and across the state.
