Lasting Solutions for Balcony Restoration & Waterproofing

As retirement communities strive to provide safe and comfortable living spaces for their residents, maintenance and repairs are essential. One common issue faced by many retirement homes is the deterioration of concrete balconies due to exposure to the elements over time, but it’s crucial they remain safe for resident use. This project on Martin Street in Milton involved the restoration and waterproofing of 19 balconies, completed successfully by following our specialised repair method and using polyurea-based materials, including a UV-resistant polyaspartic top coat.

Repair Method

Substrate Preparation

The first step in the restoration process was to remove the old vinyl flooring. This revealed the underlying concrete surface, exposing some cracks that required filling before a waterproofing membrane could be applied. All the cracks were repaired with materials designed specifically for this purpose.

Surface Coating

To achieve more lasting waterproofing results, balcony surfaces were coated with an industrial-strength adhesive which was applied to ensure the fiberglass sheets that were installed next would remain in place. These sheets provide reinforcement for the waterproofing application.

A polyurea-based waterproofing membrane was applied next, over the fiberglass. Polyurea is known for its excellent waterproofing properties, rapid curing time, and durability. This membrane forms a seamless barrier, preventing water infiltration into the concrete substrate.

The final step involved the application of a polyaspartic top coat which is not only known for its outstanding durability but also for its quick curing time, allowing for minimal downtime during the restoration process. To ensure safety, silica sand was broadcast onto the wet polyaspartic coating, creating a non-slip finish that's essential for outdoor surfaces like balconies.

Benefits of Polyaspartic Coatings

Using such membranes has many benefits, making it a coating of choice especially in outdoor applications. They cure quickly, reducing the downtime for residents and ensuring a faster return to normal balcony usage. Polyaspartic coatings are highly durable: they can withstand the daily wear and tear, including exposure to UV rays and temperature fluctuations. Chemical resistance is another sought-after quality because it protects concrete from the impact of salt and other de-icing agents. These coatings have a longer service life compared to traditional sealants or coatings, reducing the need for frequent maintenance and repairs, and coupled with non-slip aggregates they provide surfaces that are safe for use. Finally, they offer a seamless, watertight barrier, effectively preventing water.
