The advantages of in-situ testing over traditional sampling and laboratory testing are speed, quantity and quality. This series of concise leaflets acts as a guide in decision-making when specifiying in-situ tests in order to obtain the right information.

This guide focuses on geophysical testing. After an introductory guide that summarises the main benefits of in-situ testing, the other six deal with cone penetration testing, flat dilatometer testing, dynamic probing, pressuremeter testing and large-diameter plate loading tests
