When precision, strength, and reliability underpin the performance of critical machinery, engineers and specifiers want epoxy grouts they can trust. Conbextra EP120 Plus is the next-generation replacement for Fosroc’s long-serving Conbextra EP120. EP120 Plus heralds a major step forward in compressive, flexural and indirect tensile strength, and with creep, elastic modulus and coefficient of thermal expansion more closely aligned with concrete substrate for long term performance.
A two-part product that's been purpose-built for precise alignment of dynamic equipment, transferring loads and energy from equipment down into the concrete foundations. EP120 Plus withstands static and dynamic loads, and shear forces maintaining critical alignment limiting wear and tear on machinery, setting new benchmark for epoxy grout technology in Australia.
Setting the new standard in epoxy grout
Whether you're specifying large dynamic machinery, designing critical alignment components, or planning major industrial construction, Conbextra EP120+ offers unmatched performance, safety, and value:
- Higher strength
- High Effective Bearing Area (EBA)
- Wider gap capability
- Safer installation
- Designed and made for Australian conditions
Conbextra EP120 Plus isn’t just a product upgrade, it’s a category upgrade.
A major leap in performance
Conbextra EP120 Plus offers the performance features that engineers and specifiers consistently look for in an epoxy grout: high compressive strength, superior bearing area, low creep, reduced thermal expansion and reliable flow, especially when machinery alignment and long-term performance are on the line.
Exceptional strength
"With a compressive strength of 103 MPa, plus significant increases in flexural and tensile performance, along with high flow properties ensures complete contact with base plate, and critical alignment of machinery reducing wear and tear.” Mick Mckinnon
Superior flowability for faster, easier application
Across warm climates, wide gaps, and under large baseplate geometries with limited access, Conbextra EP120 Plus high flow properties ensure complete contact with base plate and critical alignment. Conbextra EP120 Plus spreads further than traditional three-part grouts due to superior flow. Its low-exotherm chemistry means large-volume pours (up to 1 m³) can be completed without excessive heat gain, curing stress, or premature thickening.
"In field demonstrations, applicators routinely remark how effortless Conbextra EP120 Plus is to place with limited access, requiring smaller header boxes, less labour, and less application time," Mick says.
High Effective Bearing Area (EBA)
A standout feature – and a key competitive differentiator – is Conbextra EP120 Plus ability to deliver high effective bearing area (EBA).
“Traditional three-part systems have reduced flow and entrain air when fillers are wet out during mixing process,” explains Mick. Once placed under a baseplate, the air entrained during mixing comes to the surface, reducing EBA and compromising alignment and load transfer. This effect is far worse in warm states like WA and Queensland, where the mixed viscosity of the three-part grouts is lower, allowing more air to rise to the surface and be trapped under base plates.
Conbextra EP120 Plus solves this through:
- A two-part, factory-controlled formulation, eliminating dry powder mixing on site.
- Fillers incorporated at manufacture and entrained air is removed.
- A flow profile that keeps defects minimal, even in large pours.
For asset owners, this ensures critical alignment is maintained, less vibration and longer equipment life.
"Conbextra EP120 Plus is manufactured using specialized mixing technology to ensure air entrained when fillers are wet out is removed, which is something competitors typically cannot replicate at site level," Mick adds.
A safer, cleaner, two-part system
Most competitor grouts are three-part systems that require applicators to handle sacks of dry filler on site, creating airborne silica hazards.
“A two-part system means no dusty fillers, no airborne silica, and much better control over mixing. Applicators notice the difference immediately," Mick says.
Conbextra EP120 Plus arrives pre-filled, pre-wetted, and RCS hazard-free, protecting crews and simplifying compliance. Combined with quicker, cleaner mixing, this significantly reduces labour time and improves mixing consistency across large projects.
Built for Australia, manufactured in Australia
EP120 Plus is developed and manufactured at Fosroc’s Wyong, NSW site. This not only ensures quality control and rapid supply but also means the formulation is optimised for Australian conditions, from WA mine sites to cold Tasmanian installations.
And while many competitors import equivalent materials, Conbextra EP120 Plus offers local manufacturing reliability including short lead times, technical support, and proven compatibility with Australian climate and specifications.
Where Conbextra EP120 Plus shines
Conbextra EP120 Plus is purpose-built for environments where heavy dynamic or repetitive loads demand absolute stability and precise alignment:
- Reciprocating machinery
- High-speed turbines
- Centrifuges
- Drop forges
- Heavy crane rails and transporter rails
- Testing equipment
- Oil and gas and petrochemical facilities
- Steelworks and refineries
Its wide gap capabilities (50–120 mm) and excellent performance in high ambient temperatures make it a versatile choice for major construction and industrial installations.
