Innovative Radar System Detects Hidden Moisture in Walls

 

Researchers at Oak Ridge National Laboratory (ORNL) have developed a microwave radar technology capable of detecting moisture within wall structures, aiming to prevent mold growth and structural damage in buildings.

The system operates by emitting microwave energy that penetrates materials like drywall and reflects off internal components such as wood sheathing. Variations in these reflections indicate moisture levels, enabling accurate detection of water accumulation within walls. In tests, the radar measured moisture content within 3% accuracy compared to conventional handheld detection meters.

Designed for practicality, the device is portable, lightweight, and user-friendly, making it suitable for residential inspections. The ORNL team is currently seeking to license the technology for commercial production and is testing its effectiveness on various wall claddings, including vinyl siding and brick.

Early detection of moisture can prevent minor issues from escalating into significant structural problems, potentially saving homeowners substantial repair costs. This radar system offers a proactive solution for maintaining building integrity by identifying hidden moisture before it leads to mold growth or structural degradation.
