Orangeburg Pipe Failure
01 · What it is
What is orangeburg pipe failure?
Orangeburg is a bituminized fiber pipe manufactured between 1945 and 1972, made of wood pulp and coal tar pitch. It softens, deforms, delaminates, and ultimately collapses with age and water exposure.
02 · Why it matters
Why inspectors flag this
Orangeburg sewer laterals are at or past their 50-year design life. Camera inspection often reveals oval deformation, blistering, or full collapse. Replacement is the only durable fix. Identifying Orangeburg in a sewer scope is a major finding that affects purchase decisions.
