Pipe Tracing and Mapping in Dublin to Find Every Drain

Our camera checks the pipe from inside, then a transmitter travels down the line to track its route and depth from the surface. You get the drains located and mapped on a site plan.

When Your Property Needs Pipe Tracing

Pipe tracing tells you where the drains run before anyone digs, builds or repairs. Find your situation below and see what a trace and site plan give you.

How We Trace and Map Your Pipes

First, we put a camera down to record the pipe from inside. Then sonde tracing follows the line from the surface, fixing its route and depth.

What Our Pipe Tracing Survey Delivers

The tracing itself is half the job. Here is what we hand over when the survey is finished.

Pipe routes marked on the ground

We mark the pipe route on the ground as we trace it. Anyone digging can see the line for themselves, so the excavator stays clear of it.

Depth readings where they matter

Depth decides how a job gets dug. We take readings at manholes, junctions and wherever your plans need them, so foundations and trenches are designed around the pipe.

A drainage map for your property

Every run, manhole and junction goes onto a site plan, either a new one or one you already have. Share it with your architect, engineer or planner.

A written condition report

The camera stage comes with a written report: each fault photographed, where it sits along the pipe and how serious it is, compiled by a certified technician.

Top service by Alec and the lads. Drains were blocked, they showed up quickly, left the place tidy after, and very reasonably priced.

We had an extremely positive experience with Davis Drain Services. Within minutes of calling them out of hours, they arrived to our house to clear a blocked septic tank. It was pumped out promptly before returning the following morning to rectify the issue. At all times they made us feel at ease and explained everything to us clearly. While on site they also provided helpful advice on how to rectify heating issues we were having. We would have no hesitation recommending them for both drainage and plumbing works. Thanks to Alec and team.

Just had Alec out to look at an issue with my boiler. We were without heat and he arrived so quickly after being contacted. He was able to pinpoint the issue straight away and had it fixed in minutes. I also asked advice on an issue with my drains that I have been encountering for a few years and he was able to give me advice on how fix it. Thank you Alec, I am very grateful for all you help.

Your Pipe Tracing Questions Answered

Straight answers to what homeowners, builders and property managers ask us before they book.

How do you trace a pipe underground?

We send a small transmitter, called a sonde, through the pipe from a manhole or access point. A receiver above ground picks up its signal, so we can follow the route and read how far down the pipe sits without digging.

Most older homes have no drainage map on record, so the reliable way to get one is a drain mapping survey. We trace every run from the surface and plot it on a new site plan or one you already have.

Yes. We map every traced run, manhole and junction onto a site plan, either a new one or your existing layout. You can share it with your architect, engineer, planner or future contractors.

Drain mapping for a typical home in Ireland costs about €150 to €450, based on published market rates. The price rises with property size, the number of pipe runs and whether you need a site plan. Commercial sites are priced after a look.

Yes, if there is any chance a drain runs under or near the footprint. Uisce Éireann must be contacted before building near its sewers, and it only considers building over one for extensions on smaller sewers. Tracing shows your architect what is there first.

Yes. Tracing is done from the surface, so nothing is dug up. A transmitter travels inside the pipe and a receiver above ground follows it, so any digging later happens only where it is needed.

Yes. Plastic pipes cannot carry a signal themselves, which is why we use a sonde. The transmitter travels inside the pipe and sends its own signal to the receiver above.

Pipe tracing shows where a pipe runs and how far down it sits. A CCTV drain survey shows what condition it is in. We use both on tracing jobs, so you get the route and the state of the pipe together.
