Allan Block Passes Full-Scale Earthquake Testing

Full-Scale seismic research confirms structural capabilities of Allan Block retaining walls under heavy earthquake conditions.
How do current SRW design methodologies compare to real life situations?

What are the actual forces present within a SRW structure?

How would an SRW perform form under the most aggressive circumstances possible – an earthquake?

To answer these questions, Allan Block Corporation, together with Huesker Geosynthetics, sponsored Columbia University on the first full-scale seismic testing ever performed on SRW walls. In the Fall of 2002, a series of three tests were conducted on Allan Block walls reinforced with Huesker geogrids at a seismic research facility in Japan.
