For drainage contractors.
Find the cause, not the next callout.
Backups that come back, water where it should not be, a camera run that shows damage the crew cannot explain. We analyze what your crews recorded, find the root cause, engineer the repair and hand you a documented concept you can execute and invoice.
What drainage contractors bring us
Recurring backups
The line was cleared, and a few months later the call comes again. Roots, displaced joints, deformation or a fall problem stay in the pipe until someone traces them.
Surcharging after rain
Manholes that overflow and yards that flood after heavy rainfall. The cause can sit far away from where the water shows up.
Damage without a clear repair path
Cracks, infiltration, structural defects. The footage shows the damage; the right method to fix it without digging is the open question.
Clients who want proof
Property owners, insurers and authorities ask for a report they can follow, not for a video file.
What we do for you
Root-cause analysis
We assess condition, hydraulics and root cause from your footage and data, remote or on site. Only then do we decide the right intervention.
Repair and rehabilitation concept
Relining, sealing, structural fixes: we engineer the complete concept for the existing pipe, designed to be executed to standard instead of ripped out and replaced.
You execute, we supervise
The physical work stays with you. We provide the concept, the method and, where needed, the special equipment, and we stay on it until handover.
A report the client can act on
Every step documented as a structured report with condition coding to EN 13508-2, shareable by password-protected link.
Reports your clients understand
SondeScan produces finished inspection reports and PDF exports automatically and shares them via password-protected link, no client account needed. Try it free for 14 days on sondescan.com.

Frequently asked questions
Can you analyze from footage we already have?
Yes. An analysis can start from existing inspection footage, plans and photos. If something is missing, we tell you exactly what to record on the next run.
Who does the repair work?
You do, or another regional contractor of the client's choice. We engineer the concept, brief the crew and supervise, we do not compete for the physical work.
Do you work in my country?
We work location-independent around the globe. Analysis, diagnosis and concept happen remote or on site; the physical works are carried out by regional partners we equip, instruct and supervise. We have worked on projects in the United States, Canada, the United Kingdom, the Gulf and Europe.
How does an engagement start?
With a call or an email describing the problem. Usually the first step is an analysis of what already exists: inspection footage, plans, measurements, photos. From that we tell you the root cause as far as it can be determined, and what we would do about it.
