Early detection services for hidden risks in Ireland
CDI
Smarter detection. Earlier insight. Better decisions.
Across Ireland, hidden risks undermine projects, budgets and long-term asset performance.
Corrosion and Japanese knotweed rarely reveal themselves early. They grow exponentially until damage is costly, hazardous, disruptive and increasingly difficult to control. Our specialist detection dogs identify risks at the earliest possible stage, giving you clarity long before traditional methods are able to confirm a problem.

Frequently asked questions
Can detection dogs find Japanese knotweed underground?
Yes. Detection dogs are trained to identify the scent of Japanese knotweed, allowing them to locate underground, dormant or concealed growth that may not be visible during a traditional survey.
How accurate are Japanese knotweed detection dogs?
When handled by trained professionals, detection dogs offer a highly accurate method of early identification. They are particularly effective in locating hidden growth that visual inspections may miss, helping reduce uncertainty during site assessments.
Is detection by dogs better than a traditional survey?
Detection dogs complement and often outperform traditional surveys when it comes to early-stage identification. While visual surveys rely on visible growth, detection dogs can identify knotweed before it emerges, allowing for earlier and more informed decisions.
Can detection dogs work all year round?
Yes. Unlike visual inspections, detection dogs are not limited by season or vegetation cover. They can operate effectively throughout the year, including when knotweed is dormant.
How long does a detection survey take?
The duration depends on the size and complexity of the site. However, detection dogs can cover large areas much faster than manual inspections, making the process efficient even for extensive sites.
Will the survey damage my property or land?
No. Detection surveys are completely non-invasive. The process does not involve digging or disturbing the ground, making it ideal for sensitive or active sites.
What happens if knotweed is detected?
If knotweed is identified, the locations are clearly marked and included in your report. You will also receive recommendations for next steps, which may include further investigation, monitoring or remediation planning.
