The Cost of Undetected Water Ingress

Water damage is one of the most common and costly causes of downtime in commercial buildings and data centres. A slow leak beneath a raised floor can go unnoticed for weeks, causing corrosion, short circuits, and structural damage. A burst pipe in an unoccupied building over a weekend can cause hundreds of thousands of pounds in damage.

Our leak detection systems provide immediate alerts the moment water is detected — giving facilities teams the time to respond before minor leaks escalate into major incidents. Automatic isolation valves provide a failsafe for unoccupied periods.

  • Immediate alarm on detection — no delay
  • Zone identification to pinpoint leak location
  • Automatic water supply isolation on detection
  • BMS integration for centralised monitoring
  • Remote notification via email or SMS
  • Data centre raised floor coverage
  • Plant room and basement monitoring
  • Trace heating for frost protection

Systems We Install

Data Centre & Server Room Leak Detection
Rope-type and spot detectors positioned at high-risk locations beneath raised floors, around CRAC units, and at pipe penetrations. BMS-integrated with automatic alerts and optional solenoid valve shut-off.
Plant Room Leak Detection
Leak detection for basement plant rooms housing chillers, boilers, and pressurisation units. Floor-level rope detection covering the entire plant room footprint with zone identification to pinpoint leak locations.
Automatic Pipe Shut-Off
Solenoid or motorised isolation valves on incoming water mains that close automatically on leak detection signal — preventing minor leaks from becoming major flood damage events.
Trace Heating Systems
Self-regulating trace heating cables for external pipework, roof drainage, and frost-susceptible plant. BMS-controlled with weather compensation to run only when temperatures approach freezing.
Cold Store & Refrigeration Monitoring
Leak detection for refrigeration plant and cold storage facilities. Refrigerant gas detection integrated with building management systems for safe area monitoring.
BMS-Integrated Monitoring
All leak detection systems are integrated with the building BMS for centralised alarm management, maintenance scheduling, and event logging. Remote alerts via email or SMS on detection.

Frequently Asked Questions

What types of leak detection systems do you install?

We install rope-type (zone) leak detection systems for large areas such as raised floors and plant rooms, and spot detectors for targeted high-risk locations. Both types can be integrated with BMS platforms for centralised alarm management and can trigger automatic isolation valve closures.

How does leak detection integrate with a BMS?

Leak detection controllers output a volt-free contact or BACnet/Modbus signal when a leak is detected. This signal is wired or networked into the BMS, which raises an alarm, logs the event, sends notifications to the facilities team, and can trigger automatic responses such as closing isolation valves or stopping pumps.

What is trace heating and when is it needed?

Trace heating uses electrical heating cables attached to pipework to prevent freezing in cold weather. It is typically required on external pipework, pipes in unheated voids, roof drainage systems, and fire suppression pipework in cold environments. Modern self-regulating cables only draw power when temperature drops, making them highly energy efficient.

Can leak detection shut off the water supply automatically?

Yes. We install motorised or solenoid isolation valves on incoming water mains that receive a close signal from the leak detection controller. This is particularly valuable for unoccupied buildings and overnight periods when a leak could go unnoticed for hours.

How quickly can leak detection be installed in a live data centre?

Most data centre leak detection installations can be completed during a planned maintenance window without taking the facility offline. We work with your operations team to schedule work during low-load periods and can phase the installation to avoid disruption to critical systems.
