PILE DRIVING ANALYSIS & DYNAMIC LOAD TESTING
Dynamic Load Testing (DLT) is a frequently used worldwide technique to evaluate the bearing capacity of piles. The Profound PDA/DLT-system is used for both DLT and for Pile Driving Analysis (PDA) as a powerful tool to control the pile driving process and reduce risks involved.

Benefits for Dynamic Load Testing:
- Faster and more cost-effective compared to traditional Static Load Testing (SLT). It allows for the assessment of multiple piles in a single day, saving time and resources
- Suitable for various types of piles, including cast-in-place, prefabricated concrete, and steel piles, making it a versatile choice for different construction projects
- Realistic simulation of actual pile behaviour under dynamic loading conditions, offering insights into dynamic pile responses that may not be captured by static tests
- Extensive correlations between simulated and actual static load tests have proven the reliability of DLT, giving engineers confidence in the accuracy of the results
- DLT meets national and international standards, such as ASTM D4945, ensuring that the testing procedures and results adhere to industry requirements
Pile Driving Analysis
Pile Driving Analysis (PDA) offers precise monitoring and analysis of hammer performance, cushion condition, pile behavior, and soil driving resistance during pile installation.
With the Profound PDA-USB conditioner, real-time signals are processed, providing instant insights into velocity, force, impedance, and other key parameters.
Graphical representations, scaled in SI units, include force-velocity profiles, energy transfer, and estimated static resistance, ensuring accurate assessment of pile integrity and soil interaction throughout the driving process.
- Reducing the risk of damage to the pile or hammer
- Reducing the risk of damage to the superstructure caused by failure of the foundation
- Optimisation of the final depth of driving, which may result in a shorter pile length
- Facilitating the prediction of pile driving and selection of the correct hammer for future projects. A quality record of each pile can be supplied to clients and authorities
Signal Matching Software DLTwave
In case you need to determine pile (ultimate) capacity and load displacement behaviour, you use the program DLTWAVE for signal matching. With the obtained signals from the DLT test, the dynamic load test is simulated in DLTWave. Both the pile and soil are modelled. Soil model parameters are automatically and interactively adjusted. Measured and calculated signals are matched to determine the capacity and the static load displacement behaviour of the pile from the DLT test results.
