Need to get piles driven faster? When structural integrity and project timelines are critical, slow-curing epoxies mean costly delays. Megapoxy 108 is the high-strength liquid epoxy binder built for speed in civil engineering, delivering 95 MPa compressive strength in just two hours. It keeps your crew moving and your project on schedule, even when conditions are damp.

Why this product exists

Megapoxy 108 was formulated to meet the demanding requirements of civil infrastructure, specifically where rapid strength development is paramount. It serves as a structural liquid epoxy binder for critical connections like bridge pile splicing, allowing heavy construction to progress quickly without compromising load-bearing performance. This rapid-set epoxy also forms a high-strength mortar when mixed with silica sand, making it suitable for durable repairs to precast concrete elements where standard concrete cure times are too long.

The numbers that matter

  • Early Compressive Strength: Achieves 95 MPa within 2 hours at 22°C for pile splicing. This allows pile driving to resume rapidly, directly reducing project downtime and associated costs.
  • Ultimate Compressive Strength: Delivers 120 MPa when fully cured. This ensures exceptional load-bearing capability and long-term durability for structural applications and high-strength mortar repairs.
  • Working Time: Offers an 8-minute working time at 25°C. This short pot life is designed for rapid application in time-sensitive operations, prioritising speed of execution for structural connections over extended workability.
  • Hydrophilic Chemistry: This resin cures effectively even in the presence of moisture. This critical feature ensures reliable performance in challenging, often damp, civil engineering environments where traditional epoxies might fail.

What it's like to use

Working with Megapoxy 108 requires precision and speed. The exact mixing ratio of 4 parts 'A' to 1 part 'B' by volume is crucial for achieving specified performance. Given the short working time, prepare all tools and substrates before mixing. For mortar applications, combine one volume of mixed Megapoxy 108 with three volumes of 50N silica sand using a slow-speed drill and propeller stirrer. Clean tools and mixing implements promptly with Megapoxy Thinners.

Where this product excels

  • Civil Construction (Bridge Pile Splicing): Ideal for joining bridge piles where the demand for 95 MPa compressive strength within two hours is critical to minimise project delays. The rapid cure and high impact strength ensure structural integrity for immediate follow-on work.
  • Precast Concrete Manufacturing (High-Strength Repair Mortar): As a mortar, it provides rapid-setting, high-strength repairs for precast concrete elements. Its 120 MPa ultimate compressive strength ensures that repaired sections are as strong, or stronger, than the original concrete.
  • Critical Infrastructure Bonding: Its ability to cure in damp conditions makes it suitable for structural bonding in environments where moisture cannot be entirely eliminated, maintaining bond integrity in challenging site conditions.

Choose this when

  • When rapid structural strength is non-negotiable: For applications demanding 95 MPa compressive strength within 2 hours.
  • When working in damp or potentially moist conditions: Its hydrophilic properties ensure reliable curing.
  • When high ultimate compressive strength (120 MPa) is required: For critical load-bearing structural connections or mortar repairs.
  • When time-sensitive civil engineering projects need fast turnaround: Such as splicing bridge piles.

Don't use this when

  • Not for: Applications requiring a long working time (e.g., more than 8 minutes at 25°C).
  • Not for: Non-sag vertical or overhead applications, as it is a liquid epoxy binder.
  • Not for: Use without precise volumetric mixing. Inaccurate ratios compromise performance.
  • Not for: Unsuitable if the minimum application temperature is below 10°C.

Megapoxy 108 is classified as a Hazardous Chemical and Dangerous Goods. Proper handling with appropriate personal protective equipment (PPE) such as safety shoes, gloves, and safety glasses is mandatory. Always refer to the Material Safety Data Sheet (MSDS) for detailed safety information and ensure adequate ventilation.

Choosing the right Megapoxy for your project

Megapoxy 108 is specifically engineered for rapid setting and early strength development in liquid civil engineering applications or as a high-strength mortar. This contrasts with other epoxy solutions that might offer longer working times or are not formulated to cure effectively in moist conditions. If your project demands speed, high early strength, and moisture tolerance in a liquid structural binder or mortar, Megapoxy 108 is the product of choice.
