Techniques and equipment for leak detection in Hoorn
We combine multiple measurement methods to reliably locate every type of leak in Hoorn, from water pipes to roofs and facades. We use equipment from FLIR, among others, for infrared imaging, geophones and correlators for pipe noise, dye and smoke for structural details, and accurate digital manometers for pressure testing.
- Thermography: infrared image detects temperature differences in floors, walls, and roofs, ideal for underfloor heating and insulation faults
- Acoustics and correlation: geophon and correlator pick up leakage sound in water pipes and determine the leak point to within decimeters
- Trace gas: a safe hydrogen-nitrogen mixture escapes through the leak and is scanned above ground with a sensitive gas detector
- Smoke and coloring: smoke test and fluorescent dye show leaking roof details, shower connections, and drains
- Endoscopy and fluid measurement: endoscope camera and capacitive resistance meters visualize hollow spaces and moisture profiles

Common leaks in Hoorn and examples
Hoorn features both historic buildings in the city center and recent construction in Zwaag and Bangert Oosterpolder. For each building type, we observe typical causes that we address in a targeted manner.
- Water pipe leakage: pressure loss, wet floor sections, or a high water bill due to a leak in a cold or hot water pipe behind the wall or under the floor
- Underfloor heating leakage: local heating and pressure drop in the circuit, often visible as a warm or cold band in the screed
- Roof leakage: water penetration on flat roofs, poor overlaps or penetrations, particularly susceptible to driving rain from the Markermeer
- Facade and cavity wall: rain penetration, defective water barrier or saturated insulation in weep holes and connections around window frames
- Bathroom and wet room: leaking sealant joints, porous grout, leaking shower drain or drain connection that only becomes visible as a ceiling stain downstairs
In case of pressure loss or wet spots in pipes, arrange immediate assistance via resolve water pipe pressure loss.

Practical cases from Hoorn with approach and result
In Grote Waal, we found a ceiling leak caused by a leaking hot water pipe in the floating screed, detected using acoustics and tracer gas, followed by targeted repair without major demolition damage. In Kersenboogerd, we solved a flat roof problem using a smoke test that revealed an open seam at a roof penetration. In the city center, thermography in winter showed a thermal bridge with penetrating damp around an old window frame with a defective water barrier in the cavity, after which a repair recommendation for the pointing and water barrier was followed in accordance with building guidelines. At the underfloor heating in Zwaag, a thermal scan showed a leaking loop, after which only a small section of the floor was opened for repair.
