Service Details
We provides professional concrete roof waterproofing services to protect exposed roof slabs, roof decks, and rooftop areas from water ingress, leaks, and long-term structural damage.
Concrete Rooftop Waterproofing
Concrete rooftops are exposed to harsh Gold Coast conditions, from blistering UV and heat to wind-driven rain and constant thermal movement. Our concrete rooftop waterproofing systems use seamless, UV-stable liquid polyurethane membranes designed to expand and contract with the building without cracking, lifting, or blistering.
Concrete Roof Deck Waterproofing Systems
Flat roof decks need a waterproofing system that can handle more than just rain. With foot traffic, outdoor furniture, planters, and equipment, the membrane must be strong enough to resist punctures, wear, and movement. We install high-durability liquid membranes and multi-layer trafficable waterproofing concrete roof deck systems suitable for exposed, tiled, or paved roof deck finishes. These systems create a reliable barrier against leaks while supporting safe, practical outdoor use.
Concrete Slab Roof Waterproofing
We deliver advanced slab roof waterproofing solutions for commercial, industrial, and strata properties across the Gold Coast & Brisbane. Our team applies industry-approved waterproofing membranes to protect concrete slabs from water ingress and long-term damage. We also provide concrete joint sealing for deteriorated joints and crack injection repairs to help restore slab integrity and prevent ongoing leak issues.

How to Prevent Water Leakage From Concrete Roofs?
Our Concrete Roof Waterproofing Process
Free On-Site Inspection & Quote
S&S Remedial waterproofing concrete rooftop provides a no-obligation, free on-site thorough inspection and written quote for waterproofing concrete roof slab across Brisbane, Gold Coast, and surrounding regions. When a membrane has reached the end of its life—showing signs of leaking roofs, bubbling, cracks, or complete failure—a surface-level fix won’t do the job.
Primer Application & Roof Sealing
Following meticulous mechanical grinding and crack repairs, we apply specialised primers and install a high-performance waterproofing concrete roof sealant engineered to withstand both Australia’s extreme UV exposure and heavy pedestrian traffic. For communal roof decks and balconies burdened by extensive water damage or failed coatings, this complete strip-and-prep method delivers a vital clean slate—restoring structural integrity with a durable, slip-resistant system.
Surface Cleaning & Preparation
To guarantee maximum adhesion, thoroughly clean the surface of all dirt, moss, algae, and debris using a pressure washer or stiff brush. Repair damaged expansion or control joint sealants and address structural cracks in concrete roofs to create a clean, stable foundation that protects your asset. Don’t skip the prep work—proper surface restoration is essential for high‑performance waterproofing concrete roof decks and roof slabs.
Roof Waterproofing Membrane
Repair Concrete Cracks
Our rip-up and redo waterproofing of rooftop is a thorough process that starts with mechanical grinding to completely remove the existing concrete roof slab 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 using SSR proven concrete crack injection method.
Curing & Final Inspection
Let the system cure fully per manufacturer guidelines. Conduct a detailed inspection and consider flood testing to confirm watertight integrity. Address any gaps or weaknesses discovered. It ensures long-term reliability, improved insulation, and a strong manufacturer-backed warranty.

Frequently Asked Question
Is primer required before concrete rooftop waterproofing?
Skipping a primer on a bare concrete roof slab is one of the quickest ways to cause a system failure, and the S&S Remedial methodology strictly enforces priming as a critical baseline step after mechanical grinding and concrete crack repair on roof slab.

Joint Sealing
Failed or deteriorated slab joints are resealed with industry‑approved sealants to prevent leaks.
Membrane Application
NCC‑compliant membranes (liquid‑applied or sheet systems) are installed over repaired areas to create a seamless, watertight barrier.
Preventive Maintenance
Regular inspections and touch‑ups extend roof lifespan and reduce costly emergency repairs.
Can a damaged old concrete roof waterproofing membrane be repaired without replacing the whole roof?
When should I choose a liquid membrane over a sheet membrane?
Liquid membranes are ideal for roofs with complex shapes, numerous penetrations (like pipes, vents, or AC units), and limited space. Sheet membranes are highly durable and excellent for large, flat, unobstructed concrete expanses.
Is polyurethane better than acrylic for concrete roofs?
Polyurethane is generally superior for exposed flat roofs because it offers higher elasticity, better UV resistance, and handles ponding water much better than standard acrylic coatings, which can re-emulsify under standing water.
What is a negative-side roof waterproofing system?
Negative-side waterproofing is applied to the inside of the structure (the ceiling below the roof). While it stops water from entering the room, it does not stop water from entering the concrete slab itself. Positive-side (top-surface) waterproofing is always preferred for roofs.
What is the role of a primer in concrete waterproofing?
A primer seals the porous concrete surface, binds residual dust, and ensures strong chemical adhesion between the concrete substrate and the waterproofing membrane, preventing delamination.
Do I need a QBCC-licensed roof waterproofing contractors from Brisbane and Gold Coast?
Yes— for jobs above AUD 3,300 or those involving structural concrete roof deck waterproofing system, such as building or commercial rooftop waterproofing, you must engage a QBCC-licensed roof waterproofing contractor. No worries—S&S Remedial’s technicians are fully licensed and qualified professionals.
Is residential and commercial rooftop waterproofing required by law or building code?
Absolutely. In Brisbane and Queensland, commercial or residential concrete rooftop waterproofing, as well as waterproofing for balconies, roof tiles, wet areas, and structural components, is mandated by building codes such as AS 3740 and AS 4654.

Does a concrete roof require a slope for waterproofing to work?
Why do membranes bubble or blister, and what should be done?
Blistering occurs when trapped air or moisture expands under the heat of the sun. Small, stable blisters might not cause immediate leaks, but large ones should be cut out, dried completely, and patched by a roof specialist.
What maintenance is required for a waterproofed concrete roof?
Keep the roof clear of leaves, dirt, and stagnant debris. Ensure roof drains, scuppers, and gutters remain completely unobstructed. Avoid dragging heavy equipment across the surface and inspect sealant joints annually.
How does thermal shock affect materials used when waterproofing exposed concrete roof areas?
Exposed concrete surfaces can fluctuate by tens of degrees between a scorching hot day and a sudden afternoon storm. This rapid change causes the concrete slab to expand and contract aggressively. To survive this thermal shock, the elastomeric membranes used for waterproofing exposed concrete roof structures must have an elongation property of 300% or higher, allowing them to stretch over structural cracks without splitting.
Can I allow foot traffic after waterproofing exposed concrete roof areas?
Standard exposed membranes are designed primarily for maintenance traffic only—such as technicians servicing air conditioning units or cleaning out box gutters. If you intend to use the area as a communal balcony or entertainment space, you must specify a heavy-duty, trafficable topcoat with anti-slip aggregate to prevent shoes or furniture from puncturing the membrane.
How often should I inspect my building after waterproofing exposed concrete roof surfaces?
You should conduct a routine inspection at least twice a year, typically before winter and after the peak of summer storm seasons. Ensure that all rainwater outlets, scuppers, and drainage grates are completely clear of leaves and debris, as standing water puts unnecessary hydrostatic pressure on any waterproofing exposed concrete roof system.
What is the most durable method for waterproofing exposed concrete roof slabs?
For long-term protection, liquid-applied polyurethane or polyurea membranes are considered the gold standard. When waterproofing roof structures, these liquids cure into a completely seamless, rubber-like skin that eliminates the risk of leaky seams or joints while offering immense resistance to standing water and intense weather conditions.
Pro Tip: Choosing a light grey or reflective white color for your exposed coating significantly reduces thermal stress. These colors reflect radiant solar heat, keeping both the concrete slab and the rooms directly beneath it much cooler.
