The challenge

We all know that deciding to construct a flat roof comes with its risk.

  • On average, it amounts to 3.31% of total construction costs.
  • We have detected more than 1 damage during construction on average
  • Statistics show that more than 50% of projects have defects in their flat roof leading to critical disruptions after handover.


Defects arise due to

  • Workmanship
  • Rush during construction & lack of quality assurance
  • Technical design issues
  • Material & other subcontractors accidentally break the roof felt.


On top of being a risk area, the risk of ingress on a flat roof increases with:

  • Solar panels (adds weight and/or penetration to the surface)
  • Green/blue roofs & roof terrace (adds layers on top of the structure which complicate leak localisation)
  • Technical installations (adds many penetrations and complications that can be difficult to seal 100%)

The solution

  • Install sensors every 15-25 m2 close to risk areas (depends on complexity of the roof).
  • The sensors are installed underneath the roof felt and insulation, but on top of the waterproofing membrane.
  • The sensors are installed by the people on site in less than a minute per sensor.
  • This gives an immediate warning as soon the roof felt has a defect and water ingresses into the insulation layer - before it becomes expensive to repair and damages the construction underneath.


Benefits of the sensors

  • A cheaper and more efficient continuous quality assurance of the work done on the roof
  • Immediate detection enabling repair costs up to 95% cheaper than later detection
  • Enhanced focus on quality throughout the project and transparency enabling better collaboration & less conflicts
  • Increased insurability & savings of up to 50% on excess related to water ingress


Roof

CLT flat roof

1 sensor every 10 to 25 m2 (depending on risk level of roof & value of interior). The sensor can be installed from below with insulated pins measuring in the top panel of the CLT.

  • Water ingress make the top panel wet, which has led to many CLT roofs rotting and losing their structural function.
  • One small defect can lead to lasting damages.

Prefabricated timber roof cassettes

1 sensor per element.


  • Can detect built in moisture during installation, can lead to mould growth.
  • 1 small hole or unsealed part in the top membrane destroys the cassette.
  • Green roof or solar panels increases risk and cost of damages.

Timber frame roof

Sensors in risk areas around dormers, chimney, ridges, etc.

  • Can detect ventilation thatisn’t done properly, leading to long term excessive moisture levels, which leads to mould growth.
  • Leakages and condensation around penetrations.

Facades

CLT walls

1 sensor every 40 m2 on average. Varies a lot based on risk profile of the building. Place sensors under windows or close to the foundation.

  • Walls are exposed to rain during construction and contractor needs to ensure right moisture levels at closure. A resource heavy manual task.
  • Walls get moisture from foundation, leakages from the roof or penetrations that aren’t sealed correctly (windows, ventilation, etc.)

Prefabricated timber facades

1 sensor every 4 elements in critical areas (top corners and bottom close to the foundation and in the corners)

  • Elements get water ingress during construction due to excess water from roof, open membranes during installation, etc.
  • Elements get excess water from surrounding construction (roof, balconies, high pressure in altitude, etc)

Timber frame walls

Sensors in risk areas

  • Walls get moisture from foundation, leakages from the roof or penetrations that aren’t sealed correctly (windows, ventilation, etc.)

Slabs

CLT slab

1 sensor every 50 sqm during construction.

  • Slabs are exposed to rain during construction and contractor needs to ensure right moisture levels at closure. A resource heavy manual task.
  • Slabs can get trapped moisture due to in-situ concrete or closure at high moisture levels.

Wet rooms

Sensors can be placed underneath wet rooms to detect undesired leaks. They can be placed on concrete slabs or CLT slabs.

  • Membranes can fail over time.
  • Rushed subcontractor work can lead to massive rework.

Balconies

Balconies have a history of being the source of many moisture damages, so 1 sensor per balcony is recommended.

  • Water can find its way in at the right wind & rain conditions.
  • Connections from the balcony to the building can be vulnerable areas.
  • If leaks are not detected, water will run into the building and damage the floors below.

Gaps in buildings

Crawl space, technical shaft, elevator shaft, areas between buildings, etc., are all areas where, if water enters, it can create lasting damage due to leaks often gets detected very late.

New building systems/techniques

Place sensors to increase trust around a new building method or new materials demand extra assurance to other project stakeholders.

Non standard methods creates worry for developer and insurance. Needs higher amount of documentation.

New material monitored today, amongst others:

  • Straw insulation
  • Wood fiber insulation
  • New timber cassettes being introduced to the market

FAQs

Is there any maintenance needed for the moisture sensors?

No, no maintenance needed. After you installed the sensor, you can sit back and relax and enjoy the data you’re about to receive. Learn more about the data.

What is the lifetime of Tector moisture sensor?

The sensor is produced to last 10 years at transmissions every 4 hours.

How moist resistant is the sensor itself?

The sensors are resistant to high moisture as they are PCB protected.

How precise and accurate is the sensor?

Measurements are very precise as the device uses a wide range resistance measurement scale (from 10 kΩ all the way to 10 GΩ). Wood moisture content: 0.3% measured at exact point (in the 8-20% range). Relative humidity: 2% RH (In the 10 to 90% range) Temperature: 0.2 °C (in the -20 to 60 degrees range). All measurements extend past this range at a reduced accuracy.

What is the connectivity of the Tectors sensor?

LoRa protocol that is widely supported and has growing coverage. Long Range communication at extremely low power consumption. Gateways cover a radius of up to 500 meters.

What if I need to set up the sensor in a hard to access place?

No problem, the sensor can be extended with wires.

How do I set up moisture sensors?

Getting started with our moisture sensor can be done in minutes. Just plug in the gateway and it works. The sensor has to be screwed in with 2 screws, and then it is registered in a few clicks by scanning a QR code on the sensor, which sends you to our system (without installing an app) and in a few clicks it is registered and operational.

How big is the moisture sensor?

Woodsense’s moisture sensor is a discreet, small sensor that can be installed anywhere.

What is the difference between a moisture logger and a sensor?

A moisture logger saves each moisture measurement locally on the logger often using an SD card or similar which later can be retrieved manually and transferred to a computer for analysis etc. The sensor will transfer the measurement to the cloud immediately making each measurement available in real-time and removes any storage limitations e.g. an SD card could have. With sensors you can access realtime data via a convenient dashboard and dont need to walk around with moisture loggers anymore.
