Stream DP

Our Stream DP array uses Equalized Scrambled Technology to control the radar signal, giving extended depth and very high resolution at the same time – so we don't have to trade one for the other. It is light enough for one surveyor to deploy and covers ground quickly.

Seeing more in the office

Back in the office we post-process the array data and find far more than can be seen on site. On one job it revealed the true size of a foul pumping chamber hidden beneath the road surface.

Recorded on site

Results are sprayed out on site in utility colours, surveyed, and overlaid on a topographic survey or your own drawing.

Need the services exposed?

Once we've located them, VAC EASE can expose, record and reinstate with vacuum excavation – one team from survey to surface, so nothing is lost between contractors.

How it works

From enquiry to delivery

The same four steps on every job, whatever the size. If you're not sure where to start, the survey finder will point you in the right direction.

  1. 01

    Enquiry

    Send us a site plan, postcode or drawings and tell us what the survey is for. We recommend the right survey and send a quote.

  2. 02

    Site visit

    Our surveyors attend site with the right equipment for the job and capture the data.

  3. 03

    Processing

    Back in the office the data is checked, processed and drawn up to your specification.

  4. 04

    Delivered

    Your survey is issued in the format agreed with you, and we're on the phone if you have questions.
