Geodetic Survey Instruments

Geodetic Targets are designed to measure deformation during tunneling and subway construction, for monitoring bridges, dams, slopes, and building structures. Survey Markers or geodetic survey markers are placed to mark significant survey points on the earth’s surface during geodetic and land surveying. Encardio-Rite is one of the leading suppliers and manufacturers of Geodetic Targets and Geodetic Survey Markers.

Model EBS-16 Building Settlement Point and Model EPS-12 Pavement Settlement Point are designed to measure vertical settlement of any concrete/rock structure or building affected by nearby excavation and construction activities.

Model ERT-10B Bi-Reflex Target and Model ERT-20P2-M1 Mini Prism Target are designed to measure deformation during tunnelling and subway construction, for monitoring bridges, dams, slopes and building structures.

The Model ESMP-10 and ESMP-11 Ground Settlement Point are used for monitoring vertical settlement on the surface of embankments & soil mass etc.

Model ERT-20P2-M1 Mini Prism Target is a copper-coated prism mounted on a swivel bracket. This target is not interchangeable.

Model ESMP-10, and ESMP-11 Ground Settlement Points are used for monitoring vertical settlement on the surface of embankments & soil mass etc. It comprises an AISI-304 stainless steel survey pin 16mm diameter, having a hemispherical top with a red coloured cross mark; MS extension rod approx. 0.5 m long 16 mm diameter; an outer protective PVC pipe having 48 mm o.d., 37 mm i.d and an MS grouting plate of 150 mm dia, 5 mm thickness. A lockable protective heavy-duty cover is available to protect the top of the installation.

The geodetic ground settlement, 3D prism targets, and survey markers/geological survey markers are extensively used in the geotechnical field for the following purposes:
