Hydrographic / Bathymetric Surveys For Your Project

Accurately Surveying Water Depths In  Lakes, Rivers, Ponds & Reservoirs

Working with Engineers across the UK, we provide hydrographic / bathymetric surveying services for a number of different projects and applications. We utilise nimble, remotely operated boats to quickly and safely acquire water depth information.

Utilising remotely operated hydrographic survey boats, we safely survey for a variety of different inland waterway projects. These include lakes, reservoirs, mines, ponds and more.

Our hydrographic / bathymetric surveying service is usually utilised during engineering projects such as dredging, construction and demolition. The compact nature of our boat allows us to survey shallow areas and compact spaces without the need for GPS signals.

The bathymetric survey information we provide can help inform key decisions. We present the water depth data in clear, easy to use CAD files  / DTM models allowing you to quickly design, take key decisions and get on with your project.

Rapid Survey Information Acquisition

Our shallow draft survey vessel is quick and manoeuvrable allowing rapid survey acquisition. We can typically provide outline results within a few hours of the survey!

Safer Than Conventional Survey Methods

We don't require an operator in a boat or wading in the shallows to pickup the water depths. Our survey boat can be safely launched by 1 person and doesn't require a crane or cradle lowered into the water.

Useful For Smaller, Complicated Projects

Our manoeuvrable survey vessel can safely operate in enclosed, dangerous spaces where conventional methods would be no longer appropriate. These include weirs, locks, water treatment plants etc.
