Why Choose Balconyguard?

Choosing Polyguard Balconyguard isn't just about finding a "waterproof sheet"; it’s about selecting a system engineered for the specific physics and logistical headaches of multi-family wood-framed construction.

1. Expect Efficiency at Scale (The "48-Inch Advantage")

Most standard waterproofing rolls are 36 inches wide. Balconyguard comes in 48-inch wide rolls, 25% Fewer Seams: Every seam is a potential fail point. By using wider rolls, you reduce the total number of laps and seams by roughly 25%.
Faster Install: In apartment complexes with hundreds of balconies, saving 10–15 minutes per balcony adds up to weeks of saved labor across the whole project

2. Built for Wood-Frame "Movement"

Wood-framed buildings are notorious for shrinking, swelling, and settling.
High Elongation: It features a 60-mil thick rubberized asphalt compound that can stretch significantly (over 700% elongation) without tearing.
If the wood subfloor develops a small seasonal crack, the membrane "bridges" it, maintaining a watertight seal where more rigid liquid coatings might crack.

3. Eliminated Guesswork (Uniform Thickness)

Liquid-applied membranes are only as good as the guy with the roller. If they apply it too thin in one spot, the system fails.
Balconyguard is manufactured to a guaranteed, uniform thickness. You don't have to worry about "thin spots" or waiting for multiple coats to cure in humid weather.
If the wood subfloor develops a small seasonal crack, the membrane "bridges" it, maintaining a watertight seal where more rigid liquid coatings might crack.

4. Specialized Tooling (Corner Boots)

The hardest part of waterproofing a balcony is the corners where the floor meets the wall.
Polyguard offers pre-formed outside corner boots. Instead of "origami-folding" a flat sheet into a 3D corner (which often leads to leaks), you just peel and stick a perfectly shaped boot.

5. Designed for Concrete Overlays

Balconyguard is specifically formulated to be used under lightweight structural concrete or topping slabs.
It won’t degrade or "bleed" when the wet concrete is poured over it, and it provides a stable substrate for tile or stone finishes applied over that concrete.

Build with Confidence

Whether you’re sealing a rough opening, wrapping a wall, or protecting against water intrusion at critical joints, the Polyguard Blue Barrier Collection delivers a complete, tested solution. It’s more than just waterproofing—it’s peace of mind for builders, architects, and property owners.
