Drainage Networks.
Managing a property or development in Greenhithe without a clear site plan is a high-risk gamble. Our Drainage mapping survey is designed to remove the “invisible” obstacles that stall Greenhithe planning applications. Using advanced electromagnetic induction and sonar tracing technology, we produce a comprehensive layout of the entire drainage network. From heritage town-center sites to modern Greenhithe business parks, we identify manhole depths, flow directions, and pipe diameters with surgical precision, ensuring your project stays on track and on budget.

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 Greenhithe clients.
Technical Site Audit
We review your Greenhithe site drawings and identify the specific areas requiring sonar tracing and depth verification.
Sonde & Trace Execution
Our Greenhithe 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 Greenhithe property.
Do I need this for my Greenhithe house extension?
Yes. If you are building over or near a sewer in Greenhithe, your build-over agreement will require a professional mapping survey.
Can you trace pipes under existing Greenhithe buildings?
Absolutely. Our Sonde technology can transmit through foundations, allowing us to map internal Greenhithe drainage lines without any excavation.
Is this survey different from a standard CCTV check in Greenhithe?
Yes. A CCTV check looks for conditions; a Drainage mapping survey provides location and depth for site plans.
