Sealed Vents
Terry Sanford HS Main Gym Crawlspace Humidity Control
Terry Sanford High School Main Gym Crawlspace Humidity Control Install a 20mil reinforced vapor barrier across the entire crawlspace floor, with all seams overlapped and sealed to create a continuous moisture barrier. A 12mil liner will be installed on all walls and piers and tied into the floor system while maintaining the required inspection gap. Sump pump systems will be installed in designated lowpoint areas to collect and discharge water away from the structure. Three commercial- grade dehumidifiers will be installed and properly distributed to maintain controlled humidity levels, with condensate lines routed for proper drainage. All crawlspace vents will be sealed using rigid foam insulation blocks and spray foam to create an airtight environment. Additional components including drainage piping, condensate lines, and minor gravel placement will be installed as needed to support system performance. All seams, penetrations, and transitions will be sealed to ensure a complete system.
