Where deep foundation are required, loads must be safely supported both structurally and geotechnically. The article with describe some practical experiences with Low Strain Integrity Test on bored type piles Benotto and prestressed reinforced concrete driven piles. In the case of bored piles with varying cross-sectional areas it is sometimes difficult to distinguish between reflections from cross-sectional changes and failure. Pile embedment limits the ability to obtain clearly recognizable pile toe reflection because the impact wave is damped out by high skin friction. This is usually in case when long piles are driven through coherent soil into bed rock.
