Moisture has been a problem in the construction industry for many years. But in the last 10 years it has become more of a problem. Everything built today seems to be on a fast track while timing of the project is essential for completion. Moisture can cause big delays on construction projects that can cost the owner or contractor a lot of money and a lot of time.

DH Tech, Inc. has developed a way to use temporary dehumidifiers and temperature control equipment to reduce problems caused by moisture on a construction site.

Problems in construction that can be caused by moisture:

• Joint compound and paint taking too long to dry
• High moisture emission levels in concrete slabs
• Hardwood and moldings not being installed under proper conditions
• Mold or mildew growing on building materials
• Material to cold to apply coatings or apply floors
• Testing inaccurate because of high humidity or incorrect temperatures

How do we solve these problems?

DH Tech uses either desiccant dehumidifiers or refrigerant-style dehumidifier or a combination of both to provide dry air inside the building to start drawing out the wet air from the building materials. This extremely dry air we are blowing into the building has a "low vapor pressure". As a result, it draws the moisture from the wet material – such as recently applied joint compound, concrete, paint, stored hardwoods, installed ceiling tiles, etc.—to let them dry at a accelerated rate.

Our Continuous Monitoring Device (CMD) can be used to take continuous readings (temperature, relative humidity, and dew point) inside the air space so we can determine if the building is getting to much or not enough dry air to maintain conditions.

Benefits for using dehumidification:

• Joint compound dries in hours instead of days
• Concrete meets manufactures standard in half the time (calcium chloride test)
• Providing proper conditions for hardwood storage and installation
• No cupping or curving of ceiling tiles
• Fireproofing is dried 3 to 5 times faster
• Prevention or mold of mildew growth
• Proper temperatures to apply materials (coatings, floor adhesives)
• Accurate testing for building materials (concrete)
