When critical civil infrastructure demands an epoxy grout that performs under pressure, Megapoxy 206 Ultra delivers. It's engineered for heavy-duty applications where high compressive and impact strength are non-negotiable. This product establishes reliable, superior-to-concrete bonds, even when confronting adverse, cold, or damp conditions. Ensure your essential structures withstand the test of time and environment.

Why this product exists

Megapoxy 206 Ultra is a two-component, 100% solids, solvent-free epoxy grout specifically engineered for civil engineering. Its formulation directly addresses the need for a hydrophilic, water-displacing material that maintains integrity in demanding environments. This grout provides high compressive and impact strength for critical applications like pile splicing, rail track grouting, and machinery grouting. It ensures reliable adhesion and cure, even when faced with cold or damp conditions, and retains its strength after prolonged water immersion.

The numbers that matter

• Ultimate Compressive Strength: 115MPa. This ensures load-bearing structures, such as bridge bearing pads and pile repairs, exceed the strength of conventional concrete, resisting deformation under extreme loads.
• Tensile Bond Strength to Steel: 9.5MPa. Critical for secure anchoring applications like setting anchor bolts and locking PT cables, guaranteeing the bond holds firmly to metal components.
• Flowable, poured under 5mm plates. This characteristic allows precise placement in tight clearances, ensuring complete encapsulation for applications like grouting machinery bases or filling truncation pockets.
• Shore D Hardness: 80. A high Shore D value indicates excellent resistance to impact and abrasion, vital for floor repairs and machinery backing parts subjected to heavy wear.
• Pull-out Strength for 25mm rebar: >150kN. This robust anchoring performance, particularly for rebar inserted 8 to 10 times its diameter into 40MPa concrete, confirms its suitability for heavy-duty structural fixings.

What it's like to use

Mixing Megapoxy 206 Ultra requires precision: combine 5 parts Part A to 1 part Part B by volume. Thorough mixing for 3 minutes, using a mechanical stirrer at low speed, is essential to achieve the stated physical properties. The mixture should be applied immediately after mixing, as its work time is 30 minutes at 25°C. For cooler conditions, expect an extended work time. The minimum application temperature is 10°C. Clean tools and mixing implements with Megapoxy Thinners promptly after use.

Surface preparation is critical for optimal adhesion. Concrete surfaces must be free from grease and laitance, typically achieved through mechanical abrasion like grit blasting or grinding. For metal, grit blasting to AS 1627.2.2002 is recommended; otherwise, mechanical abrasion to a bright metal finish followed by degreasing is necessary. All existing coatings must be removed for maximum bond strength.

Where this product excels

• Rail Infrastructure: Megapoxy 206 Ultra provides strong, durable bonds for rail track grouting and integrates seamlessly with systems like Delkor Rail, ensuring long-term stability under dynamic loads.
• Structural Concrete Repair: It excels in pile splicing, pile repair, and core hole filling, developing compressive strengths superior to concrete and maintaining integrity even in damp environments.
• Heavy Machinery Grouting: The high compressive and impact strength makes it ideal for grouting machinery, backing crusher parts, and setting anchor bolts, reducing vibration and wear in industrial settings.
• Bridge and Civil Works: Used for bridge bearing pads and locking PT cables, its excellent strength retention after water immersion provides confidence in critical infrastructure exposed to the elements.

How it fits in a real system

Megapoxy 206 Ultra frequently serves as the foundational adhesive in critical civil engineering projects, notably in rail system installations. It is typically the first material applied when bonding components like the Delkor Rail System to the substrate. Its role is to establish a high-strength, load-bearing connection that is integral to the overall system's stability and longevity. This primary positioning ensures structural integrity from the outset, supporting subsequent system components under demanding operational conditions.

Choose this when

• When the application demands an epoxy grout with compressive strength superior to concrete, such as for heavy-duty structural repairs or machinery foundations.
• When working in adverse conditions including cold or damp environments, and you need reliable adhesion and cure.
• When you require a flowable grout that can be poured into tight spaces, including under plates as thin as 5mm, for complete encapsulation.
• When specifying for civil engineering projects with critical load requirements, including rail track systems, bridge bearing pads, or deep anchoring.
• When the application requires AS/NZS 4020:2005 compliance for contact with drinking water.

Don't use this when

• Not for: bonding to unprepared or coated surfaces where full bond strength is required. This will result in inferior adhesion, compromising structural integrity.
• Not for: applications where a precise 5 Part A to 1 Part B mixing ratio or thorough mechanical mixing cannot be strictly followed. Inaccurate mixing leads to lower physical properties and potential cure failure.
• Not for: applications requiring a fast-setting or rapid-cure material. Megapoxy 206 Ultra has minimum cure times ranging from 12 to 48 hours depending on temperature, making it unsuitable for quick turnaround projects.
• Not for: general-purpose adhesive tasks where minimal surface preparation is acceptable. Optimal bonding requires specific preparation like grit blasting or mechanical abrasion.

Megapoxy 206 Ultra: Engineered for Extremes

Unlike conventional grouts or general-purpose epoxies, Megapoxy 206 Ultra is a solvent-free, hydrophilic water-displacing, flowable epoxy grout specifically engineered for heavy-duty civil engineering applications. It provides high compressive and impact strength superior to concrete, adheres and cures effectively even in cold or damp conditions, and maintains excellent strength retention after prolonged water immersion, rather than simply filling gaps or providing basic adhesion. Its formulation and performance are purpose-built for critical infrastructure demands where standard products would fall short.
