Keller

What Keller does

Keller Australia (Keller Pty Ltd) is the Australian operating subsidiary of Keller Group plc, a UK-listed (LSE: KLR) global geotechnical engineering contractor and the world's largest in its field, with operations in more than 40 countries across six continents. Founded in 1860, Keller has operated in Australia for over 60 years, built on legacy brands Piling Contractors, Vibropile, Frankipile, and Keller Ground Engineering. The company provides a comprehensive portfolio of geotechnical solutions organized into four core service areas: ground improvement (mass mixing, vibro compaction, rigid inclusions, ground freezing), deep foundation systems (CFA piles, bored piles, driven piles, micropiles, Franki piles, Atlas piles), grouting solutions (jet grouting, compensation grouting, permeation grouting, mine infill), and earth and water retention (secant walls, diaphragm walls, sheet piles, anchors, soil nails). Keller serves commercial, industrial, infrastructure, institutional/public, power, and residential end-markets through a design-and-build delivery model combining in-house engineering with one of Australia's most extensive specialized piling and drilling equipment fleets.

The business operates on a project-based revenue model, winning work primarily through competitive tenders with major contractors (Lendlease, Hickory, Walker Corporation, Delta Group, Fulton Hogan JV) and government agencies (Queensland Department of Transport and Main Roads, Homes Victoria, Perth New MetroRail). Pricing is contract-specific across design-and-construct and construct-only engagements, typically on multi-year horizons. FY2025 group revenue was £3.09bn with 5.9% growth, and an H1 2026 trading update indicated FY2026 revenue materially ahead of £3.15bn consensus, supported by a record £1.9bn order book. Recent strategic actions include the February 2026 acquisition of US design-build firm Hoffman Planning, Design & Construction, a £100m share buyback, a 41.6% dividend increase, and sustainability-focused partnerships (Green Energy Hire for hybrid battery systems, Webcor/CEMEX for low-carbon concrete) that cut grout plant CO2 emissions by over 90% and achieve 270 kg CO2-eq/m3 in drilled-shaft mixes.
