Smart water management for CLT buildings and flat roofs

Tector watches moisture in the structure. Pipe leaks are the other water risk - and our partner Quensus stops them at the source: LeakNet meters the supply, detects abnormal flow and shuts off the water automatically. One scope covers both.

Prevent escape of water

LeakNet flow meters and smart valves catch abnormal flow from pipework, risers and appliances - and shut off the supply where configured.

Know your water

FlowReporter tracks consumption in real time and sends alerts to the right people - leaks, waste and usage in one view.

Track moisture

Tector’s embedded sensors follow drying in CLT panels and watch for ingress beneath flat-roof membranes.

Two risks, two systems

A pipe leak shows up as abnormal flow on a meter. Moisture trapped in a CLT panel or under a roof membrane never does - and a sensor embedded in the structure cannot see a burst pipe behind a riser. Covering a building against water damage takes both principles, from construction into operation.

Flow-based detection - Quensus LeakNet

LeakNet meters the incoming water supply, learns normal usage, alerts on abnormal flow and can shut off the water automatically through smart valves.

  • Escape of water from pipework, risers and plant rooms
  • Automatic shutoff where configured, with alerts to the right people
  • Splash sensors and leak cable for spots where water pools
  • Occupied buildings, complex layouts and multi-storey programmes

During construction

Watch standpipes and temporary site supplies while the building is still being fitted out.

In occupation

Catch tenant leaks, appliance failures and burst pipes as abnormal flow, and shut off the supply automatically where configured.

Moisture-based monitoring - Tector

Wireless sensors inside the structure track wood moisture content, temperature and relative humidity continuously.

  • Probes read moisture inside the timber, not just wet or dry at the surface
  • Drying evidence before walls, floors and roofs are closed in
  • Live dashboard, threshold alerts and documentation for handover
  • Stays in place from construction through operation

CLT and timber structures

Follow drying in the panels from erection through enclosure, and keep watching for elevated moisture once the building is in use.

Flat roofs

Detect water beneath the membrane and localise it on the roof plan, continuously between inspections.

What the claim statistics actually show

How does water damage actually split between pipe leaks and water from outside? The insurers’ claim statistics do not give one tidy number - each series measures its own market, population and years - but they are clear about the shape of the risk:

  • Norway: insurers registered 109,920 water damage claims in the record year 2023. More than one in three was caused by water entering from outside; in a typical year it is just over one in five, with the rest starting inside the building (Finans Norge water damage statistics).
  • Sweden: in the insurers’ joint water damage survey, 58 per cent of the investigated damages were caused by leaks from pipe systems - and three out of four of those pipe leaks traced back to corroded, worn-out pipes (Vattenskadecentrum, 2019 claim data).
  • Denmark: 70,000 homeowners reported a water damage caused by pipe failure in 2022, up from 46,000 in 2010 (Forsikring & Pension figures via Bolius). Cloudbursts caused close to 23,000 water damage claims in the record year 2023 and almost 12,000 in 2025, in an analysis covering about 91 per cent of the Danish insurance market (Forsikring & Pension weather analysis).

No single series captures both risks cleanly - they measure different populations in different years. Together they still say enough: pipe systems and other sources inside the building produce a steady, high volume of claims, water from outside produces a substantial share that spikes in wet years, and a building is only covered against water damage when both are watched.

Why scope both together

Escape of water and envelope moisture are usually handled by different suppliers, scoped at different times and discovered by different people. That is how coverage gaps appear.

  • One scope: pipework and envelope moisture covered for the same project.
  • One point of contact: start with Tector or with Quensus - the other is brought in when your project needs it.
  • Evidence through every stage: flow data from the supply, moisture and drying records from the structure, from construction into operation.

Technical detail: how LeakNet works

  • Flow meters on the incoming supply measure continuously; LeakNet learns the building’s normal usage pattern and flags abnormal flow.
  • Smart valves shut the water off automatically where configured - or on demand from the app.
  • Splash sensors and leak cable detect pooling water in plant rooms, washrooms and voids, and can trigger shutoff.
  • FlowReporter delivers consumption reporting and alert notifications to the right people.
  • Runs on temporary site supplies during construction and stays on the finished building in operation.

Key benefits

Automatic shutoff

WRAS-approved smart valves close the supply the moment flow looks wrong - remotely or automatically, configured to your building.

Learns normal usage

LeakNet learns the building’s consumption pattern and alerts on abnormal flow, so an alarm means something is actually wrong.

Cuts waste and bills

Consumption tracking shows where water goes - Quensus reports customers reducing water bills by up to 60 per cent.

Recognised by insurers

Quensus reports escape-of-water claims cut by over 80 per cent, and partners with UK insurers including Aviva.

Site to occupation

Protects standpipes and temporary supplies during construction, then risers, plant rooms and washrooms in operation.

One scope with moisture monitoring

Pair LeakNet with Tector’s embedded sensors so the supply and the structure are covered together.

From planning through occupation

  1. Planning: agree the flow-protection scope and moisture-sensor coverage before work starts.

  2. Construction: watch temporary site supplies; follow drying and roof conditions.

  3. Handover: live leak protection and a documented moisture history from day one of operation.

  4. In operation: abnormal flow is stopped at the valve, and alerts reach the right people.

Frequently asked questions

What does Quensus LeakNet actually do?

LeakNet meters the building’s incoming water supply, learns what normal usage looks like, and alerts on abnormal flow. Where smart valves are fitted, it shuts the water off automatically. Splash sensors and leak cable extend detection to spots where water pools, and FlowReporter delivers consumption reporting and alerts.

Why do I need flow detection as well as moisture monitoring?

They see different risks. A flow meter detects escape of water from the supply side - pipework, risers, appliances - but nothing about the building envelope. Embedded moisture sensors detect water in the structure - rain under a membrane, construction moisture in a panel - but nothing about the pipes. Most CLT and flat-roof programmes carry both risks from construction into occupation.

Does LeakNet work during construction?

Yes. It can watch standpipes and temporary site supplies while the building is being fitted out, and the same system then protects the finished building in operation - so the protection does not stop at handover.

How do Tector and Quensus work together?

Quensus scopes and delivers LeakNet; Tector scopes and delivers the moisture monitoring. You can start with either company - we coordinate directly so your project is scoped once, with each system delivered and supported by its specialist.

What if I only need pipe-leak protection?

Then go straight to Quensus: their team quotes and delivers LeakNet independently of Tector. You can request a quote at quensus.com.
