GRLWEAP is a one dimensional wave equation analysis program to simulate motions and forces in a foundation pile when driven by either an impact or vibratory hammer. Since initially developed in early 1970s, the program has been improved continuously to add many features which help improve the accuracy of predicted stresses, bearing capacities, blow counts and installation time. The accuracy has been improved and proven by matching the results with field observation and measurement by the Pile Driving Analyzer®.

GRLWEAP is the software of choice for industryleading piling professionals around the world.GRLWEAP:
- Calculates driving resistance, dynamic pile stresses, and estimated capacities based on field observed blow count, for a given hammer and pile system
- Helps select an appropriate hammer and driving system for a job with known piling, soil and capacity requirements
- Determines whether a pile will be overstressed at a certain penetration or if refusal will likely occur before a desired pile penetration is reached (driveability analysis)
- Estimates the total driving time
