Cost-Effective Investment
Waterproofing is not just a repair—it’s a preventive solution. By protecting your concrete surfaces now, you avoid expensive repairs, structural damage, and premature replacements in the future.
Why Is Residential and Commercial Roof Waterproofing a Necessity?
Preventing Structural Damage
Concrete is porous by nature. Without rooftop or flat roof deck waterproofing system, moisture can penetrate through the surface, reaching steel reinforcements and causing rust, expansion, and concrete spalling. This compromises the strength of the entire structure.
Protecting Against Leaks and Water Stains
Unchecked water penetration often leads to unsightly stains, leaks into living areas, and damage to ceilings or walls below. Industrial and commercial roof waterproofing ensures these issues are prevented before they start.
Mould, Mildew, and Health Risks
Moisture trapped in decks and balconies can create a breeding ground for mould and mildew, which not only damages materials but also poses serious health risks for occupants.
Cost Savings in the Long Run
Waterproofing roofs, balconies, kitchen, decks, bathrooms, terraces are preventive investment. Repairing water damage, structural cracks, or replacing failed roof decks or balconies can be extremely costly. Proper waterproofing avoids these expenses and extends the lifespan of your outdoor space.
Our Roof Deck, Balcony & External Waterproofing Details
At SS Remedial, we take pride in protecting Gold Coast homes and businesses with reliable outdoor waterproofing solutions. Whether it’s a leaking balcony, a weather-worn deck, or exposed outdoor areas, our process ensures long-lasting protection against water damage, structural issues, and costly structural repairs.
Inspection & Assessment
Every project begins with a thorough site inspection. We assess your facade, patio, balcony, deck, or outdoor area to identify cracks, membrane failures, drainage issues, or signs of water ingress. This allows us to recommend the most effective waterproofing system for your property.
Waterproofing Application
Apply primers, and install a new, high-performance waterproofing roof sealant designed to withstand extreme weather and UV exposure. This method provides a clean slate and is ideal for roofs with multiple layers of failed waterproof roof coatings or extensive water damage.
Surface Cleaning & Preparation
This creates the perfect foundation for a seamless waterproofing system.
- Remove existing coatings or failed membranes
- Repair cracks and damaged substrates
- Ensure surfaces are clean, dry, and ready for application
Detailing & Sealing
Repair Cracks and Weak Spots
Our waterproofing is a thorough process that starts with mechanical grinding to completely remove the existing roof waterproofing membrane and any delaminated material. This allows us to expose the bare roof slab for inspection and repair. We then address any cracks or structural weaknesses.
Quality Check & Handover
Project Showcase
Three Mistakes Builders Often Make when Waterproofing Balcony, Roof Deck and Floor
Inadequate or Incorrect Slope (Drainage Failure)
Failing to install the concrete slab or substrate with a sufficient slope (fall) to the drain or edge of the balcony, or installing the tiles/topping slab without the correct slope. Often, builders or contractor aim for a “flat” look. It will result to water ponds, which accelerates the breakdown of the flat roof deck waterproofing membrane, tile grout, and adhesive.
Improper Detailing at Junctions and Penetrations
Failing to properly seal the most critical, high-movement areas, such as: Where the balcony floor meets the wall (the wall/floor junction or “upturn”). Around railing posts, drains, scuppers (outlets), and door thresholds. These joints and holes are the weakest points in any concrete balcony waterproofing systems.
Using the Wrong Concrete Balcony Waterproofing Systems or Low-Quality Materials
Selecting a waterproofing product that is incompatible with the substrate, the climate, the movement of the building, or the final floor finish. Builders may also cut costs by using a system that does not meet the necessary thickness or application requirements specified by the manufacturer or building codes. Always ask if your builder have licensed concrete balcony membrane waterproofing contractor that can issue certification.
Puncturing or Damaging the Waterproofing Membrane
The waterproof membrane is installed correctly, but it is damaged by other trades (railing installers or glass installers, tilers, electrician) who drill, drop tools, or walk on the membrane without proper protection before the final floor finish is applied.
Stop the Leak. Protect Your Home. Secure Your Family’s Comfort
Don’t wait for water damage to compromise your ceiling or concrete structure! If you notice damp patches, cracked grout, or water stains beneath your balcony or concrete deck, these could be signs of failing waterproofing.
