Waterproofing a Flat Roof of an Apartment Roof

Rescue My Concrete’s customer needed a superior waterproofing membrane with a long warranty period for the flat roof of this apartment complex.

The Rescue My Concrete Team was able to offer and then install a premium quality spray-applied polyurethane water-proofing membrane that was backed by us, Rhino Linings Australasia. The customer used this project to showcase the Rescue My Concrete Teams’ expertise to their client. The client was so impressed by the result that they won another prestigious project.

Installing a Premium Waterproofing Membrane

The Rescue My Concrete Team is pretty certain that the high-quality water-proofing membrane that was installed contributed to their customer’s success. The Rescue My Concrete Team is also confident that their client will have peace of mind knowing they will not have to worry about having any water ingress from the roof for years to come.

Among standard challenges, The Rescue My Concrete Team had to pay particular attention to overspray. Since this building was constructed within a block of existing buildings and offices, normal work-life activities continued in close proximity to the construction site.

Since this type of membrane is a plural component spray application, particles become airborne during operations.

Overcoming Challenges with the Waterproof Membrane

Needless to say, the building’s location and height provided gusty winds, meaning they had to apply their experience and skills to control any contamination and damage to other buildings or vehicles. This was even more challenging at the top of the staircase roof, the highest point of the building with no balustrades.

Another challenge was accommodating the particularities of the roof construction. The top slab was not only a hollow core slab (usually more prone to movement) with a top screed, but it also had an additive for waterproofing in the substrate.

Addressing Water Ingress and Complex Substrates

The Rescue My Concrete Team found the right methods and products and installed the membrane according to Rhino Linings’ recommendations.

Yet another challenge was the multitude of substrates (concrete, screed, plastic, copper, polymers, and joints) to which The Rescue My Concrete Team seamlessly applied the membrane from horizontal to vertical (penetrations, risers, structures, parapet, etc.).

Frequently Asked Questions:

1. What’s the best way to waterproof a flat roof?

The best way to waterproof a flat roof is by using a high-quality, spray-applied polyurethane membrane. This method ensures a seamless, durable, and flexible barrier that can adapt to the roof’s surface, offering long-term protection from water ingress. Surface preparation, overspray control, and the proper application of the membrane are critical factors for ensuring successful waterproofing.

2. What is the best membrane for waterproofing?

Polyurethane membranes are the best waterproofing membranes and are widely regarded as one of the top choices. They offer superior durability, flexibility, and resistance to environmental factors, making them ideal for flat roofs and other surfaces prone to movement or exposure to harsh conditions.

3. What is water ingress?

Water ingress refers to the unwanted penetration of water into a structure through cracks, gaps, or porous materials. Over time, water ingress can lead to significant damage, including mold growth, structural weakening, and interior damage. Proper waterproofing solutions, such as applying a high-quality membrane, can effectively prevent water ingress and protect the integrity of the building.
