Waterproofing Systems South Coast
Waterproofing, concrete sealing and surface protection solutions for concrete, rendered and exposed surfaces across residential, commercial, industrial and strata projects.
Waterproofing & Surface Protection
Protect Concrete, Rendered & Exposed Surfaces from Moisture Damage
Water ingress is one of the most common causes of concrete and building deterioration. Without the right protection, moisture can contribute to cracking, corrosion, mould, surface failure and long-term structural damage.
Austech Cement provides waterproofing systems and concrete sealing across the South Coast, helping protect concrete, rendered and exposed surfaces from moisture damage, surface wear and everyday exposure.
Based in Dolphin Point, we work from Wollongong to Eden across residential, commercial, industrial and strata projects.
Concrete Waterproofing & Surface Protection
Waterproofing and Sealing for Long-Term Surface Protection
Waterproofing and sealing both play an important role in protecting building surfaces, but they are not the same.
Waterproofing systems are designed to help stop water from penetrating a surface or structure, while concrete sealing helps protect the surface from moisture, staining, wear and contaminants.
Austech Cement assesses the surface condition, exposure, usage and project requirements before recommending the most suitable waterproofing or sealing solution. Our focus is on proper preparation, practical system selection and long-term protection.
Waterproofing Systems
Our waterproofing systems are designed to help protect concrete, rendered and exposed surfaces from water ingress and moisture-related deterioration. These systems are commonly used in remedial works, building upgrades and areas exposed to ongoing moisture, weather or traffic.
CWS100 Waterproofing Applications
Austech Cement can apply CWS100 waterproofing solutions where suitable for the project. CWS100 is designed for concrete waterproofing and protection, making it particularly effective for large, exposed concrete areas subject to thermal stress or high traffic.
Concrete Sealing
Concrete sealing helps protect surfaces from water absorption, oil, staining, contaminants and general wear. It can improve durability, make surfaces easier to clean and help extend the lifespan of concrete in residential, commercial and industrial environments.
Surface Preparation & Protective Coatings
Proper preparation is essential for reliable waterproofing, sealing and coating performance. Depending on the surface, this may include cleaning, grinding, crack repair, patching or preparing the substrate for adhesion. Protective coatings may also be recommended where additional resistance to moisture, traffic, weather or environmental exposure is required.

CWS100 is particularly effective for rooftops, podium decks, car parks, wharfs, marine structures, bridge decks, water tanks and swimming pools. It is also trafficable within 6 hours of application for suitable car park and high-use applications, helping reduce downtime where fast return to service is important.
CWS100 comes with a 25-year manufacturer’s warranty, helping provide long-term peace of mind for waterproofing and concrete protection projects.

Applications
Where Waterproofing Systems Are Used
Waterproofing systems may be required wherever surfaces are exposed to water, moisture, traffic, weather or ongoing environmental conditions. The right solution depends on the structure, exposure and intended use of the area.
Applications include:
Balconies and podium decks
Rooftops and exposed concrete areas
Car parks and trafficable surfaces
Wet areas and high-moisture environments
External walls and facades where suitable
Water tanks and swimming pools

Signs of Waterproofing Failure
Damage Caused by Waterproofing Failure
Failing or inadequate waterproofing can lead to serious structural and aesthetic issues. Moisture can enter concrete, rendered surfaces or building structures and cause damage that becomes more costly over time.
Common problems include:
Water Leaks
Moisture entering internal or external areas can cause visible staining, dampness and damage.
Cracked or Deteriorating Concrete
Water can weaken concrete over time, especially when it reaches cracks, joints or exposed areas.
Concrete Cancer & Spalling
Moisture can contribute to corrosion of steel reinforcement, leading to cracking, rust staining and concrete breaking away.
Mould & Damp Issues
Ongoing moisture can create unhealthy environments and affect internal finishes.
Surface Staining & Wear
Water, oil and contaminants can affect the appearance and durability of exposed concrete surfaces.
Concrete Sealing
Concrete Sealing for Surface Protection
Concrete sealing is a practical way to protect concrete surfaces from moisture absorption, staining, surface contaminants and everyday wear. It is often used after surface preparation, grinding or repair work to help improve durability and maintain the appearance of the concrete.
Concrete sealing may be suitable for:
Driveways and paths
Patios and outdoor areas
Garages and car parks
Commercial floors and walkways
Industrial surfaces
External concrete areas
Prepared or repaired concrete surfaces
Depending on the surface and product used, sealing may provide a natural, matte or slightly enhanced finish.
Waterproofing vs Concrete Sealing
What Is the Difference Between Waterproofing and Concrete Sealing?
Waterproofing and concrete sealing are both protective systems, but they are used for different purposes.
Waterproofing
Waterproofing is designed to help stop water ingress and protect structures from moisture penetration. It is often used in high-risk areas such as rooftops, podium decks, balconies, wet areas, exposed slabs and remedial projects.
Concrete Sealing
Concrete sealing helps protect the surface from moisture, stains, oils, wear and contaminants. It can improve the appearance and maintenance of concrete, but it is not always suitable as a full waterproofing solution where water pressure or constant moisture is present.
Austech Cement can assess your project and recommend whether waterproofing, sealing or a combination of both is required.
Our Process
Our Waterproofing & Sealing Process
From surface assessment to final checks, we take a practical approach to waterproofing, sealing and concrete protection.

Surface Assessment
We assess the area, surface condition, exposure risks and signs of moisture damage before recommending a suitable waterproofing or sealing approach.
Step 2
Preparation
Proper preparation is essential. This may include cleaning, grinding, crack repairs, patch repairs or preparing the surface for adhesion.
Step 3
System Selection
We select a suitable waterproofing, sealing or protective coating system based on the substrate, exposure and project requirements.
Step 4
Application
The selected system is applied using professional techniques, with care taken to achieve consistent coverage and reliable performance.
Step 5
Final Check
We inspect the completed work for consistency, finish and suitability before the project is handed over.

Johnny
Austech were called out to fix some cracked render on my arch. Rather than simply patch the render, the team did an investigation to determine the cause of the cracking. The repair was done properly, and I now have a guarantee the crack will never return. They had a great knowledge of products and techniques to get the job done right.
