Experts will testify Tuesday about what Chinese drywall has done to people's homes and lives, according to the Associated Press.
U.S. District Judge Eldon Fallon will hear the testimony in a non-jury trial.
Homeowners who re-built after Katrina in Louisiana and Mississippi, along with people in four other states, say the tainted drywall caused fixtures and appliances to corrode and adversely affected their health.
Some have even lost their homes and are living in tents outside of their houses.
Homeowner won't testify.
An attorney involved in the case says another thousand cases could be tried individually.
