The cross-hole is a non-destructive method of analysis that allows to make accurate checking, high-resolution, quality of deep foundation structures (such as piles, diaphragms, etc.) through the use of ultrasound to obtain an overall systematic description of
the cracks occurred.
It is used also in the interventions of consolidation of foundation soils, but also for the analysis of above-ground structures.
Direct sampling allows to derive parameters of great use for the evaluation of the mechanical properties (strength and deformation), and chemical and physical properties of the materials investigated.
The drill consists of taking, in situ, cylindrical sample of concrete with a coring machine.
You can make cores with different diameters and then performing crushing tests in lab. This is a direct method, as it provides a measure of the resistance to compression, without the use of correlations with other parameters.
Of different use are micro-core sampling (diameters of the crown 40-60 mm) and usually useful to calibrate the instrumentation used for ultrasonic investigations and / or to carry out an inspection punctual and semi-destructive of wall elements or of concrete.
