Paragon

Protect your balcony from water damage

Once water seeps past the membrane, it rots the plywood and joists. You may not see the damage until it’s severe. A small leak can compromise the entire balcony structure.

Our membrane systems withstand Vancouver’s heavy rainfall, with drainage that keeps the surface dry. A well-installed membrane also shields the building below, preserving your property’s value.

Prevent Water Damage

Peeling membrane on your balcony lets water soak into the wood framing underneath. Without a waterproof barrier, rot spreads fast. We install a Balcony Membrane that seals every seam and directs rainwater away from your home.

Our system uses a sloped underlayment that channels water to a drain, so nothing pools. Your deck stays dry and the structure lasts for years without costly repairs.

Membrane Installation Techniques

Liquid-applied membranes like polyurethane or PMMA cure into a seamless rubber-like sheet. This design removes seams at penetrations. Sheet systems made from reinforced PVC or TPO are heat-welded to create watertight laps.

Installation starts with a tapered mortar bed or pre-sloped underlayment board that has a minimum two percent grade. Fiberglass reinforcement strips are embedded into the wet membrane at inside corners, floor-wall transitions, and drain openings.

The membrane wraps up parapet walls and under door sills. It then receives a wear course of mineral cap sheet or urethane topcoat for pedestrian use.

Waterproofing and Drainage

The waterproofing layer serves as the main drainage plane above living space. It integrates with the wall’s weather-resistive barrier behind the cladding. A cant strip at the wall base helps with the transition so the membrane isn’t stressed at the right angle.

Through-wall flashings and metal drip edges direct water away from the building below. Where a balcony meets a door, the sill pan flashing must overlap the membrane upturn to keep the water-shedding surface continuous.

Vapor-permeable systems let trapped moisture escape outward, which prevents blistering and rot. Movement joints allow for expansion differences between the balcony structure and the exterior wall.

Local Bylaw Requirements

In the City of Burnaby, you need a building permit for work that affects a structure. For balcony membrane work, a permit may be required if the job impacts the building envelope, so be ready for possible inspections.

In the City of Vancouver, balconies on multiple dwellings can only extend up to 1.8 m into a required yard. The safety railing must not be higher than 1.07 m above the balcony floor. If your membrane project includes rebuilding or altering the balcony, these limits could affect your design approvals.

The City’s bulletin says balconies and decks usually cannot extend into required yards unless the district regulations allow it. If your membrane replacement involves changing the balcony assembly, your project may need to meet these zoning rules and permit requirements.

Community Impact Through Care

A local school faced problems with balcony membranes on several classroom wings. These membranes were leaking water, which could damage the plywood sheathing. The school couldn’t close the balconies while students were using them, as this would risk more damage. Our team created a plan to replace the membranes in stages. We worked after hours and made sure each wing was safe while classes were in session. When we finished, every membrane was sealed, and the building was secure, eliminating the risk of leaks.

How much does a balcony membrane system cost?
Balcony membrane waterproofing costs range from $3,000 to $26,000. The price depends on the coverage area and type of system you choose. For example, a 50 m² area with a single-ply membrane starts around $3,000, while a larger 200 m² built-up membrane can reach $26,000.
We begin with a tapered mortar bed or pre-sloped underlayment board set to a minimum two percent grade. Next, we apply the membrane, embed fiberglass reinforcement at corners and transitions, and finish with a wear course like a urethane topcoat for foot traffic.
