Testing Traditional Materials for Flood Resilience
The National Park Service partnered with the US Army Corps of Engineers’ Construction Engineering Research Laboratory (CERL) in 2018 to conduct laboratory tests of traditional materials in simulated flood conditions. One goal of these tests is to understand how various traditional materials, finishes, and assemblies react to inundation, drying, and cleaning. Materials and finishes that have been tested include soft brick, structural clay tile, plaster, stucco, lime wash, beadboard, old-growth lumber and siding, and several common floor types.
A second goal of the tests is to provide data comparable to many modern construction materials in the Federal Emergency Management Agency’s (FEMA) Technical Bulletin 2-08, Flood-Resistant Materials Requirements for Buildings Located in Special Flood Hazard Areas in accordance with the National Flood Insurance Program.
Although the tests have not yet yielded conclusive decisions regarding the ratings of various materials in the FEMA framework, the test results and data may be useful in various applications.
Round 1. Completed in 2019; this study used ASTM E3075-16, “Standard Test Method for Water Immersion and Drying for Evaluation of Flood Damage Resistance” to test sample wall and floor assemblies.

Round 2. Nearing completion; this study also used ASTM E3075-16 to test individual materials isolated from the assemblies previously tested in Round 1. US Army Corps of Engineers report and NPS interpretation of results are in progress.
Round 3. Began in February 2024.
