Quality Control Of Concrete Piles Feature

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[…]

5 Integrity Problems of Concrete Piles

Deficiency of concrete materials is a common problem in Bored Pile construction. This is mainly because integrity problems of concrete piles can affect the load bearing capacity and load distribution properties. Piles and deep foundations transmit top structure loads to strong substrate through friction and/or standing on bed rock. This load transmission is performed effectively when no Read more about 5 Integrity Problems of Concrete Piles[…]

Reuse of Existing Piles Feature

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[…]

How to Perform Pile Integrity Test

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. Pile integrity test (PIT), or as ASTM D5882 refers to it as low strain Read more about How to Perform 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?[…]

How to Use GPR for Evaluation of Concrete Piles

How to Use GPR for Evaluation of Concrete Piles

Detection and evaluation of unknown foundations of old construction, particularly buried piles can be a big challenge, because: * No structural drawing is available. * The access to the piles is difficult, if not impossible. * The traffic or operation of (or over) the superstructure can not be interrupted. Certain non-destructive methods have been developed over years Read more about How to Use GPR for Evaluation of Concrete Piles[…]

Non-Destructive Evaluation of Unknown Foundations

Non-destructive evaluation of unknown foundations and piles has gained interest among engineers and researcher over the past few years. Latest research show the effectiveness of these methods in investigating the depth and quality of existing piles, as well as in the quality assurance of new construction. Piles are structural members made of timber, steel, or Read more about Non-Destructive Evaluation of Unknown Foundations[…]

Why and When to Use Concrete Piles?

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 soil layers. Read more about Why and When to Use Concrete Piles?[…]
