CLT buildings and buildings with flat roofs

Pipe leaks show on a flow meter, but moisture trapped in CLT panels or beneath a flat-roof membrane does not. Flow-based detection protects pipework, risers, and site supplies. Embedded sensors track wood moisture, temperature, and humidity where water never passes a meter. Most CLT and flat-roof programmes need both from fabrication through occupation.

Above 20% wood moisture content, timber is generally considered too wet to enclose. The exact number matters less than the drying trend, probe placement, and whether wet areas can still vent. Keep affected panels open where possible. If enclosure is unavoidable, use active venting, heat, or air suction until readings fall into a safe range.

Surface or splash sensors only tell you if the face of a panel is wet or dry. Screw-in probes read moisture inside the CLT lamella, where drying decisions actually matter. That depth reading is what insurers and project teams need before walls and floors are closed in.

Yes. Sensors placed beneath the roof build-up can detect moisture under the membrane before it reaches the deck or spreads into the building below. That is a different risk from pipe leaks and needs its own monitoring approach alongside any flow-based protection.

Ideally in planning, so sensor coverage and insurer evidence are agreed before work starts. CLT drying is tracked from fabrication through encapsulation. LeakNet can protect site standpipes and temporary supplies during construction, then monitor occupied pipework once the building is live.

Quensus scopes and supplies LeakNet for flow-based escape-of-water protection and coordinates embedded moisture sensors from Tector for CLT and flat-roof programmes. In partnership with Tector, we help you define the right mix for your project size, layout, and insurer requirements.
