High-Strain Dynamic Load Testing (PDA) is widely used to evaluate the load capacity and structural integrity of piles, providing fast, accurate, and reliable analysis for foundation validation.
Applied in infrastructure, building, energy, mining, and special foundation projects, PDA testing is essential for risk reduction, cost optimization, structural safety, and regulatory compliance.
Request a QuoteEssentially, the PDA test consists of installing specialized sensors on the pile shaft to capture and process, in real-time, the data generated by the impact of a driving hammer or a free-fall system.
As a result, we obtain crucial information about the soil-pile interaction and the foundation's performance under dynamic load.

Leveling the pile top and preparing the surface for sensor attachment and impact execution.
Attaching two pairs of diametrically opposed accelerometers and strain gauges, connected to the PDA equipment.
Controlled blow with a hammer/ram on the pile top, generating stress waves that travel through the shaft.
Real-time acquisition and analysis of force and velocity signals by the PDA, followed by CAPWAP analysis.
Determination of mobilized load capacity, structural integrity, and shaft friction and tip resistance distribution.
