Weather changes like rain, wind, or snow can bring water into commercial buildings, enough to cause damage to the structure and gradually lead to interior deterioration through time. This is the reason why roofs and walls, and entry points like windows and doors are built strong. They need to withstand the harsh elements and protect the building interior. But these exterior features need the help of effective exterior commercial waterproofing to make them more durable and able to endure the constant weather exposure.

Air Sealing

An exterior commercial waterproofing system utilizes air sealing barriers to ward off water intrusion. Walls are caulk-sealed at the bottom plates and inner corners.Caulking and spray foaming are also done on joists, sub-floors and door thresholds to seal other possible points of water entry.

The rough openings in door and window exteriors can also be air-sealed with the use of backer rods or latex-based spray foams. In air sealing, exterior commercial waterproofing contractors often take steps not to void any existing warranty.

Air sealing is also done to the electrical and plumbing systems, such as wires, boxes, or sheathings. Any damage in these fixtures must be repaired first before air sealing. Other entry points like lighting fixtures, cable wire holes, and the like, are also sealed.
