Title: VERTICAL MOISTURE BARRIER UPDATE
Accession Number: 00625717
Record Type: Component
Availability: Find a library where document is available Abstract: Damages from expansive soils in the United States exceed $10 billion a year. The challenge has been addressed by international conferences, universities, research institutes, and federal, state, and local organizations. The concept of minimizing volumetric change by minimizing moisture change led to the use of a vertical moisture barrier. The Texas Department of Transportation (TxDOT) first used a vertical fabric moisture barrier on a 1/2-mi section of Interstate 410 with a fabric bid price of $20/lineal-ft. The latest TxDOT project has 14 mi of these barriers, at a cost of $6/lineal-ft. Nineteen vertical fabric barrier projects are reported. Annual maintenance costs have been reduced, and repeated resurfacings are no longer necessary. Vertical moisture barriers can minimize these destructive movements.
