Quality Control of Concrete Piles

Quality control of concrete piles is a challenging task. Engineers, and contractors rely on experience and well-established procedures and test standards to verify the strength, and consistency of pile materials. Non-destructive testing help reveal potential defects that might have happened during pile casting (in the case of cast-in-place piles), or transportation and installation (in the Read more about Quality Control of Concrete Piles[…]

Practical Considerations in Pile Testing

Pile Integrity Testing (PIT) is a non-destructive testing method for evaluating the unknown length and integrity of piles and deep foundations. The basic concept behind the technique is determining the velocity (required) and force (optional) response of pile induced by an impact device (normally, a handheld hammer). Pile Integrity Testing works best for long structural component such Read more about Practical Considerations in Pile Testing[…]

Reuse of Existing Piles – How NDT Can Help

Safety, reliability and satisfactory performance of structures require a well-planned maintenance program, as well as remedial actions in short and mid-term. Existing structures that are designed in accordance with older design codes or were built by older construction practices may need to be extensively repaired, rehabilitated, or replaced within the next few years. The remedial Read more about Reuse of Existing Piles – How NDT Can Help[…]

What is Pile Integrity Test ?

Construction and installation of concrete piles and deep foundations is a challenging task. Problems can occur during the process, which in turn results in defects in pile components. Pile formation problems, Concrete faults, and reinforcement installation issues are among the most common problems. The resulting defects can negatively impact the durability and mechanical performance of Read more about What is Pile Integrity Test ?[…]

How to Evaluate Concrete Piles?

Structure inspection manuals such as the Ontario Structure Inspection Manual (OSIM) mostly emphasizes on the visual inspection and physical condition of bridge structures. The visual inspection methodology in this guideline consists of close up visual assessment of defects in the superstructure and substructure. This methodology is limited to inspection of elements that are at the arms Read more about How to Evaluate Concrete Piles?[…]

Why and When to Use Concrete Piles?

Concrete Piles and drilled shafts are an important category of foundations. Despite their relatively high cost, they become necessary when we want to transfer the loads of a a heavy superstructure (bridge, high rise building, etc.) to the lower layers of soil. Another reason for choosing a pile foundation is the condition and quality of Read more about Why and When to Use Concrete Piles?[…]
