A construction site without a moisture control plan can produce a negative effect. Let's look at where and how risks emerge and what technology is available to mitigate issues:

Moisture and water risks:

A. High humidity and water intrusion can promote microbial growth.

B. Slow drying moisture-latent materials like concrete and gypcrete can push schedules due to unmet flooring specs.

C. High moisture levels can delay wallboard activities because of damaged drywall, slow drying joint compound, and joint failure repairs.

D. Fireproofing dries slowly inside enclosed areas and can trigger mold.

E. Hardwood flooring and millwork can absorb moisture from the air or wet slab, resulting in warping and bending.

F. Under-drying mass timber wood products or excessive moisture can extend timelines and lead to staining, degradation, and mold. Overdrying can lead to cracking, checking, and delamination.

G. Wet concrete slabs can compromise mois­ture-sensitive adhesives and can lead to early failure.

H. Faulty fixtures and broken pipes can trigger a water event or slow, hidden leak, causing damage and mold.

Other risks:

I. Use of in-house HVAC to manage condi­tions may void warranty and impact future occupants.

J. Running equipment when not required wastes energy, labor, and money.

K. Excessive heat, cold, dust, and fumes can have adverse effects on sensitive equipment and worker productivity, health and safety.

Smart Construction Drying Solution

A Polygon solution delivers treated air to target areas via temporary duct. A network of sensors alerts personnel to potential issues and tells equipment when to turn on/off to proactively maintain conditions. Dehumidification removes ambient moisture, which speeds up material drying and prevents mold.

The system can mitigate other issues, too. It avoids an early start of the permanent HVAC, protecting the warranty. It can create ideal conditions for workers’ comfort, promoting produc­tivity and health. It can monitor IAQ, VOC, and dust levels to support a healthier environment. Lastly, it can operate autonomously, reducing oversight and energy consumption, making it a sustainable and economical solution.

Involve your climate control partner early

To reduce the most climate- and moisture-related risk, get your climate control partner involved before you break ground. Partners can be valuable at many stages of the building lifecycle from design to build to occupancy.
