The "No-Dig" Intelligence: How We Map
Precision Data Without the Excavation.
Old-school mapping involved “exploratory” digging and guesswork. Our modern Drainage mapping survey uses non-invasive technology to see through the ground.
- ◉ GPS Tagging: We can provide coordinates for every major junction and manhole on your site.
- ◉ Depth Accuracy: Critical for avoiding "utility strikes" during excavation or piling works.
- ◉ Integration Ready: Our data is presented in a clear format that your architects can easily overlay onto their existing site plans.
Non-Invasive Site Mapping
Our workflow is designed to minimize site disruption while maximizing data accuracy for our Islington clients.
Technical Site Audit
We review your Islington site drawings and identify the specific areas requiring sonar tracing and depth verification.
Sonde & Trace Execution
Our Islington engineers use non-invasive electromagnetic equipment to “paint” the underground infrastructure above ground.
Digital Data Delivery
We compile your Drainage Mapping Survey into a professional pack, including site maps, schedules, and HD footage.

Frequently Asked Questions
Can you map drains under existing buildings?
Why do I need a mapping survey instead of just a CCTV check?
A CCTV check looks for conditions (cracks/blocks). A Drainage mapping survey looks for location and direction. You need this for legal site plans and construction.
Do you provide AutoCAD files?
What is a Drainage mapping survey?
It is a technical process using sonar and cameras to find the exact location, depth, and direction of underground pipes across a Islington property.
Do I need this for my Islington house extension?
Yes. If you are building over or near a sewer in Islington, your build-over agreement will require a professional mapping survey.
Can you trace pipes under existing Islington buildings?
Absolutely. Our Sonde technology can transmit through foundations, allowing us to map internal Islington drainage lines without any excavation.
Is this survey different from a standard CCTV check in Islington?
Yes. A CCTV check looks for conditions; a Drainage mapping survey provides location and depth for site plans.
