Membrane failure leads to costly repairs

Once water gets beneath a failing balcony surface here, the real threat isn’t just the puddle you see—it’s the silent decay eating away at the structure below. A small tear can let moisture reach the wood framing, and with our rainy seasons, that rot accelerates before you even notice a drip inside. We stop that progression by installing a durable barrier that locks water out from day one.

A new membrane also enhances how you use the space. It creates a smooth, comfortable surface that stays cooler in summer and resists mold and mildew. This makes the balcony feel like a true extension of your home, where you can walk barefoot or leave furniture out without worrying about damage.

Effective Balcony Protection

Pooling water on your balcony can cause serious damage. If not fixed, moisture can rot the base and leak into your home’s exterior walls. A well-installed membrane seals the surface and directs water away, stopping these issues before they start.

Our team removes old materials, fixes any damaged base, and applies a seamless membrane system. We bring this same skill to every balcony membrane in Vancouver. This creates a watertight balcony that holds up against regular use and weather, giving you a safe, dry outdoor area without the risk of structural damage.

Coquitlam's Unique Weather Challenges

Coquitlam’s rainy weather and damp conditions wear down balcony surfaces quickly. Without proper waterproofing, water can seep into the deck structure, leading to expensive exterior repairs. Our team knows the local building styles and weather patterns in Coquitlam.

We customize membrane solutions to handle the heavy rain and freeze-thaw cycles common in this area. A strong, seamless coating stops water from getting in and keeps your balcony safe all year, so you can enjoy your outdoor space no matter the season.

Balcony Membrane Installation

In Coquitlam, installing a balcony membrane starts with exposing the concrete slab. Workers grind the slab to create a slope of at least 2% toward the drains. This slope helps prevent standing water from soaking in. Any cracks or damaged areas are filled with a special repair mortar that sticks to the concrete, making a smooth surface before waterproofing.

Next, a two-part polyurethane or PMMA liquid membrane is applied over the entire deck and up the walls at least 6 inches. These materials cure into a seamless, flexible sheet that moves with the building while staying attached. In Coquitlam’s wet climate, moisture-resistant primers are often used to allow application on concrete that isn’t completely dry, so rain doesn’t delay the work.

Water and Vapour Control

A balcony membrane in Coquitlam needs to be both waterproof and allow vapour to pass through. In winter, warm air from inside can push moisture out into the cold slab. A membrane with the right perm rating lets vapour escape instead of forming condensation under the coating. We carefully install flashings at door thresholds and wall intersections to guide water away, stopping it from entering the building.

The membrane must also resist wind-driven rain that can come from above. A continuous metal drip edge at the outer edge helps direct water away from the fascia. Each end point gets a bead of high-quality sealant to stop capillary action, which is a common failure point during Coquitlam’s rainy season.
