Home > Services > CompressionThis test is used to measure the axial deflection of a vertical or inclined deep foundation when loaded in static axial compression. These methods apply to all deep foundations, regardless of their method of installation, and may be used for testing single piles or pile groups. This vertical compression pile maintained load test is usually carried out to ensure the structural and geotechnical soundness of the pile and also to predict settlement of other piles. The usual procedure is to increase the load in stages until the proposed working load and a certain factor of safety is reached and then to unload and to leave the load off until the rise or rebound substantially ceases , the test in standardized by ASTM D1143
