Concrete is a porous material. It absorbs water. There are spaces in the concrete that are not possible to see. Higher the porosity higher the absorption of the water. There are advantages and disadvantages to having the porosity of the concrete. For example, being the ports, allows water to penetrate into the concrete.

The top of the investigated piles was prepared by flattening the concrete surface. The preparation length was ∼0.5 m because according to [28], the transducers must be placed approximately 300 mm apart and the impact position must be at a distance of 150 ± 10 mm from the first transducer (Fig. 2).The P-wave test position was in the centre of the pile.
