Essential for Quality Control

Dharti uses its in-house survey crew and equipment to conduct hydrographic and topographic surveys to support our operation at various dredge areas. With a variety of hydrographic field equipment we can use our boats locally or fit portable equipment for use on locally available vessel.

Our experienced surveyors use the latest instruments and software to ensure a fast and cost effective field to finish solution. We often use topographic survey to tie in the upland areas into our hydrographic surveys to provide our clients with a seamless survey though the tidal zone.
