Now, let’s dive deeper into each system.

What is Rediwall?

Rediwall is a PVC-based permanent formwork system designed for quick and efficient wall construction. Manufactured by AFS, it’s widely used for basements, retaining walls, and commercial buildings due to its pre-finished surface, minimal waste, and fast installation.

Unlike traditional formwork, Rediwall panels lock together easily, eliminating the need for extensive on-site cutting or finishing. Once installed and filled with concrete, Rediwall forms a strong, durable wall with high moisture resistance—making it a reliable choice for various structural applications.

Pros of Rediwall

Fast Installation: The snap-lock system enables quick and hassle-free assembly, reducing labour time and costs.
Low Maintenance: The pre-finished PVC surface eliminates the need for rendering or additional finishing, saving time and materials.
Strong and Durable: Once filled with concrete, Rediwall provides high structural integrity, making it suitable for load-bearing applications.
Lightweight & Easy to Handle: Compared to traditional formwork, Rediwall is lighter, making transportation, handling, and installation more efficient.

Cons of Rediwall

Limited Fire Rating: Some Rediwall systems may not meet fire compliance requirements without additional fireproofing treatments.
Waterproofing Considerations: While moisture-resistant, Rediwall may require external waterproofing for basements and underground structures to prevent water ingress.
Steel Reinforcement Needed: For load-bearing applications, steel reinforcement must be installed inside the walls to achieve maximum structural strength.

What is Dincel?

Dincel Structural Walling is a polymer-based permanent formwork system designed for fast, durable, and structurally sound wall construction. Unlike traditional formwork, Dincel panels interlock seamlessly, creating a hollow form that is then filled with concrete for high-strength load-bearing walls.

Pros of Dincel Wall

What sets Dincel apart is its integrated fibre reinforcement, which enhances crack resistance and structural integrity. It is widely used in basements, retaining walls, and commercial developments, offering built-in waterproofing and compliance with Australian fire and building standards.

Integrated Waterproofing: Dincel’s built-in waterproofing system eliminates the need for additional membranes, making it ideal for basements, wet areas, and underground structures.

Fire Compliance: Meets AS3600 (Concrete Structures Code) and AS5113 (Fire Spread Testing), ensuring it complies with Australian fire safety regulations.

Minimal Waste: Dincel panels are pre-cut to size, reducing on-site material wastage and improving construction efficiency.

Structural Efficiency: The polymer composition and fibre reinforcement improve crack resistance, reducing the need for additional reinforcements while maintaining structural integrity.

Cons of Dincel

More Complex to Cut: Although pre-cut to size, on-site modifications can be more challenging compared to Rediwall, requiring specialised tools.

Higher Initial Cost: Dincel panels are generally more expensive per square metre than Rediwall, though long-term savings on waterproofing and compliance may offset this.

Installation Requires Precision: Misaligned panels can be difficult to correct once installed, making careful handling and accurate placement essential.

Rediwall vs Dincel: Head-to-Head Comparison

Choosing between Rediwall and Dincel comes down to key factors like cost, installation, durability, compliance, and sustainability. Here’s how they compare:

1. Cost Comparison

Rediwall is generally more affordable in terms of material costs.

Dincel has a higher upfront cost, but its integrated waterproofing and fire compliance can lead to long-term savings.

Both systems help reduce labour costs compared to traditional blockwork, thanks to their quick installation.

2. Installation Process

Rediwall features a snap-lock system, making assembly fast and straightforward.

Dincel uses a click-together system, but requires precise alignment to avoid installation issues.

Both systems are lightweight, making transportation and handling easier than conventional formwork.

3. Durability & Lifespan

Both systems offer high durability and are resistant to moisture, pests, and rot.

Dincel’s fibre-reinforced polymer enhances crack resistance and adds extra structural integrity.

Both require concrete filling to achieve maximum strength and longevity.

4. Compliance & Certifications

Dincel is fire-compliant and certified under AS3600 (Concrete Structures Code) and AS5113 (Fire Spread Testing).

Rediwall offers fire-rated options, but some applications may require additional fireproofing.

Both systems meet Australian NCC standards for permanent formwork.

5. Sustainability

Both Rediwall and Dincel use recyclable materials, reducing environmental impact.

Dincel holds an Environmental Product Declaration (EPD) certification, making it a more eco-friendly choice.

Each system has its strengths—Rediwall is cost-effective and quick to install, while Dincel excels in waterproofing, fire compliance, and durability. Your final choice should depend on your project's specific requirements.

Rediwall vs Dincel: Which one should you choose?

Which Structural Walling System Should You Choose?

The best choice between Rediwall and Dincel depends on your project's specific needs. Here’s a quick guide to help you decide:

Choose Rediwall if:

You need a cost-effective and fast-to-install solution.
Your project has less stringent fireproofing and waterproofing requirements.
You want a pre-finished surface that requires minimal maintenance.

Choose Dincel if:

You need integrated waterproofing, especially for basements or wet areas.
