Extensometer is one of the geotechnical instrumentations that used to measure and locate settlement, heave, displacement and deformation in soil and rock. By using settlement plate and extensometer the settlement could be measure, it can also use in certain depth or wide range soil layer. Extensometers typically used for monitoring excavations, foundations, dams, embankments, tunnels, shafts and sheet piles..

Inclinometer are used for monitoring lateral movements and deformations in soil, rock and retaining structures. The tools availability either as portable or In-place (IPI) devices for the measurement of lateral movement.

Piezometers refers to the tool used to measure pore water pressure and groundwater levels within soil and rock in specific point. The range of piezometers used for understanding the site or project condition, determining the safe rate for placement, designing for the lateral pressure, evaluating the effectiveness of drainage and also early warning monitoring system for predicting the slopes base on soil behaviour and degree of consolidation. Piezometer best for measure the dynamism of pore water pressure during the reclamation, pile driving, embankment work and excavation.
