GRL Engineers Inc. is celebrating 40 years of serving the deep foundations industry. The company was founded in March of 1976 to provide the innovative service of testing piles by the high strain dynamic pile testing (HSDT) method. It started with just three engineers and now has 34.

Although a considerable percentage of GRL projects still involves HSDT with the Pile Driving Analyzer system and CAPWAP software, GRL has added many other services to its offerings over the past four decades; notably thermal integrity profiling and cross-hole sonic logging of drilled shafts, pulse echo pile integrity testing, GRLWEAP wave equation analysis of piles, static load tests and more.

GRL’s 10 regional offices serve the entire U.S. and some international locations. The locations now perform high strain dynamic testing not only on site, but also remotely, which saves travel time and money; and not only on driven piles, but also on drilled shafts and augered cast-in-place piles. 

GRL says its engineers are truly ‘the foundation testing experts and are more than willing to share their expertise. When they are not testing foundations, they present at conferences, collaborate with universities, write journal papers or manuals of industry practice, are active in committees of various professional associations, and support colleagues all over the world with insight.
