Waterproofing ● Flashing
WATERPROOFING
A good water repellent will form a bond with the masonry without a visible film. Water repellents act as a deterrent, causing water to bead up rather than pervade into the wall and corrode the anchors and structural steel.
Another key element in choosing the right water repellent for any commercial structure is breathability or the ability to allow moisture and vapor to pass out of the masonry substrate.
PMR also offers elastomeric coatings as an alternative method of waterproofing. Elastomeric coatings are a popular means of waterproofing because they can be applied like paint and have exceptional water sealing properties.
Waterproof Deck Coatings
The purpose of a waterproofing or coating is to preserve the integrity of the coated concrete surfaces and prevent water from entering the concrete or filtering to levels below.
Specializing in parking garages, plaza decks, balconies, and other commercial structures, PMR offers a variety of colors and finishes to beautify and protect these and other concrete surfaces.
WALL FLASHING
A wall flashing is a thin piece of impenetrable material installed behind the masonry facade to prevent water penetration.
Why are Wall Flashings Needed?
Weathering is one of the leading causes of water damage. Such deterioration can be caused by rain, humidity, and snow. To block water intrusion adequate wall flashings must be installed.
A masonry facade is very permeable, even well constructed walls can not be completely sealed. Often problems arise around newly formed cracks, mortar joints, windows, and vents.
Once the water penetrates these areas it will run between the exterior of the wall and the structural components, rusting and deteriorating anchors that tie the brick veneer to the backup wall.
Severe damage often appears where the water collects such as at shelf angles, wall bases and lintels, that is why those are the key areas for wall flashing installation.
