The Essentials of HOKLAS Pile Testing Hong Kong
Before any building is constructed load tests are carried out to assess the bearing capacity of the foundations. This in effect determines how well the piles work for the future purpose and also how the subsoil performs in relation to a pile. Of course, this type of testing is absolutely essential and, quite literally, at the foundation of any type of building development.
However, traditionally pile testing has been expensive which often leads to less load tests with lots of gaps that are filled with industry knowledge and assumptions too. Any type of process that creates a more effective solution is attractive and our HOKLAS pile testing Hong Kong focus means that developers in the area can benefit by being able to reduce the number of load tests that they carry out.
PIT or pile integrity testing is a way of assessing the quality of piles and because it can be carried out quickly this enables a large number of piles to be tested. The way in which this works is using equipment that detects changes in speed of a compression wave that indicate issues with a pile. The low strain impact test is a non-destructive test and is really cost-effective.
A PDA or pile driving analyser, records hammer blows to create a measurement about the strength of the blow and the stress on the pile as well as its bearing capacity.
When it comes to concrete piles are already fixed in place a method to evaluate any problems that may need to be dealt with is a method called sonic logging. This is an effective way to check the structural integrity of piles and is considered to be one of the best-performing checks.
Structural soundness needs to be established before any above-ground development and the most thorough form of integrity testing is required. There are a multitude of defects that can be detected that need to be addressed and properly dealt with. Damage to pile walls and honeycombing as well as cracks are just a few of the complications that can undermine a pile’s integrity.
This is the stage of construction when experience and the best equipment and methods are absolutely vital. Cutting corners or making too many assumptions about piles from gathering the bare minimum can lead to problems later which could be far more expensive to rectify. This is why
