Frequently Asked Questions
Can you map drains under existing buildings?
Why do I need a mapping survey instead of just a CCTV check?

Do you provide AutoCAD files?
What is a Drainage mapping survey?

Do I need this for my Welwyn Garden City house extension?
Yes. If you are building over or near a sewer in Welwyn Garden City, your build-over agreement will require a professional mapping survey.
