Part Number:Profound - STATNAMIC - Pseudo Static Load Testing

Statnamic is an innovative method for testing the load bearing capacity of foundation piles. Compared to static load testing: 90-95% less weight has to be loaded. Dependent upon the weight to be tested, Statnamic enables you to test up to 6 piles per day at much lower costs.

Statnamic pile testing is based upon launching a reaction mass. For catching the fall back of this reaction mass, Statnamic uses unique techniques based upon gravel and hydraulic systems. Profound has developed Statnamic together with Berminghammer Foundation Solutions.


Statnamic Load testing is performed in 4 stages. To prepare the test, the cylinder with pressure chamber is connected to the pile head and the reaction mass (only 5-10% of the load tested) is placed over the piston. The test starts with igniting the solid fuel propellant inside the pressure chamber, generating high-pressure gases and accelerating the reaction mass. At this moment, the actual loading of the pile takes place.

The space caused by the upward movement of the reaction mass will be filled by gravel. The gravel catches the reaction mass and transfers the impact forces to the subsoil.

The applied force, displacement and acceleration are directly monitored. All signals are measured by the Profound data acquisition system whereby the mobilized capacity and static load displacement behavior can immediately be presented in a load-displacement diagram.
