The static load test (PCE) is the only test capable of directly determining the load vs. displacement curve of the top of the pile, information of great importance for foundation design. It can be performed on all types of piles, vertical or inclined, regardless of the execution or installation process in the ground, including caissons.

The test consists of applying forces to the test pile (compression, tension or horizontal) with progressive load increases and recording the corresponding displacements, resulting in a load vs. displacement graph.

To apply forces to the test pile, it is necessary to use reaction elements, such as tension piles. In its tests, Fountest Engenharia uses reaction piles from the site, which are very competitive in works with excavated piles, or reusable piles, such as helical piles, which are very competitive in works with driven piles. We also design tests with reaction piles in metal profiles and their welded locking, generally used as a reaction in driven test piles.

We have the best equipment for reading load and displacement (imported load cells and deflectometers, duly calibrated), in addition to monitoring the test via video, which ensures safe and smooth execution even in the event of rain or strong winds, for example.

We propose, prepare and manage the installation of strain gauges along the pile shaft for instrumented static load testing, which allows the separation of the friction load and the pile tip for the test loads. All instrumented bars from Fountest Engenharia are calibrated in our own laboratory, with the measurement presented in a report.

The direct load test (PCD) provides the load vs displacement curve of the tested soil surface, and is indicated for determining the maximum support stress of the soil.
