Geodetic Survey Instruments

Geodetic Targets are designed to measure deformation during tunnelling and subway construction,for monitoring bridges, dams, slopes and building structures. Survey Markers or geodetic survey markers are placed to mark significant survey point 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.

Prism Target

This unit consists of a mini prism mounted on a universal joint such that it can be oriented in any direction as required. A copper coated prism is used in the target.

​Convergence bolt of zinc plated steel constructions with protective cap, an adaptor with a plastic reference break-off point is available with the supply. The break-off point adaptor is required to mount the target on the convergence bolts. The prism target and its mounting componentsare is made of high performance materials and precise manufacturing processes. The target is thus, interchangeable.

Building Settlement Point

This building settlement points are used extensively for measurement of vertical settlement of any concrete/rock structure or building affected by nearby excavation and construction activities. The unit consists of a spherical reference locator with threaded bolt. The reference locater is fixed on a vertical wall or a structure to monitor settlement of structure/building.

Settlement readings of are taken with a digital auto level. To determine settlement, an initial or base reading is taken before the construction starts. Subsequent readings (taken during construction) are then compared with initial reading as reference.

Pavement Settlement Point

This settlement point is used to monitor vertical settlement of a pavement or road. It is suitable for applications where the top layer of the road is asphalt. The unit consists of a plastic tapered disc and a special retaining nail. It is suitable for use on a concrete surface, tiles or asphalt road.

​Settlement readings of are taken with a digital auto level. To determine settlement, an initial or base reading is taken before the construction starts. Subsequent readings (taken during construction) are then compared with initial reading as reference.

Soil Settlement Point

Settlement points are used for monitoring vertical settlement on the surface of embankments & soil mass etc. It comprises of an AISI-304 stainless steel survey pin with a hemi-spherical top with a red colored dot mark, MS extension rod, an outer protective PVC and a MS grouting plate. A lockable protective heavy duty cover is available to protect the top of installation (to be ordered separately).

​Settlement readings of are taken with a digital auto level. To determine settlement, an initial or base reading is taken before the construction starts. Subsequent readings (taken during construction) are then compared with initial reading as reference.
