By using the reflected wave method, the instrument is used to assess the integrity of concrete pile and identify the extent and location of the pile defect. It can be used for testing drilled piles and hammer piles. It can also be used for testing the exposed top surface of constructions such as pillars. The testing and monitoring of the structural behavior of foundation piles are regulated by technical regulations for construction, which govern the design, construction, and structural monitoring of both new and existing structures. In this article, we will delve into the static load test on foundation piles, pile integrity testing (PIT), and the cross-hole ultrasonic test. We will also recommend five Novatest tools to perform these tests efficiently and reliably.
