What Mainmark Ground Engineering does
Mainmark Ground Engineering is a privately held Australian specialist in non-invasive ground engineering and asset preservation, founded in 1989 on the NSW Central Coast in the wake of the Newcastle earthquake. The company addresses foundation subsidence, ground settlement, voids, soil liquefaction and structural unleveling across residential, commercial, infrastructure, mining and utility customers in Australia, New Zealand, Japan, Thailand, Vietnam and the United Kingdom, delivered through 18 regional offices and approximately 253 staff.
The core offering is built around three proprietary, trademarked technologies: Teretek® (engineered polyurethane resin injection that compacts weak soils, fills voids and lifts structures through small-diameter injection points), Terefil® (a flowable, lightweight cementitious grout for soil replacement, large void filling and pipe abandonment), and JOG Computer-Controlled Grouting (a multipoint cementitious injection system capable of running 25–400 injection points for precision re-levelling of medium-rise to high-rise buildings, mining assets and major infrastructure). Documented outcomes include ±10mm re-levelling tolerances, up to 500% increases in ground bearing capacity, and project completions measured in hours or days rather than weeks.
Mainmark generates revenue through project-based, quote-driven service contracts delivered via direct field sales teams, with no public pricing or distributor channel. Pricing is bespoke per project, and the funnel is supported by technical content marketing, industry publications, and conference participation. Customers include asset owners, councils, construction firms, mining operators, utilities and homeowners, with named engagements spanning Sydney International Airport, Christchurch Art Gallery, Bega Cheese, Amana Living, Yarra Trams, Comdain Infrastructure and rail operators in Australia and the UK. The firm maintains ISO 9001, ISO 14001 and ISO 45001 certifications (since 2017) and is led by CEO Peter Bierton with Chief Growth Officer Amy Williams appointed in 2026 alongside a new strategic alliance with Mitsui & Co.

Mainmark Ground Engineering product offering
Product offeringCore offering
Mainmark Ground Engineering delivers non-invasive ground engineering and asset preservation solutions using proprietary resin injection (Teretek), cementitious grouting (Terefil), and computer-controlled multipoint injection (JOG). The company remediates foundation subsidence, re-levels sunken structures, fills underground voids, and abandons decommissioned pipes across residential, commercial, infrastructure, mining, and utility sectors. Services are delivered as project-based contracts through 18 regional offices across Australia, New Zealand, Japan, Thailand, Vietnam, and the UK.
Product overview
Mainmark Ground Engineering offers a portfolio of specialized non-invasive ground engineering and asset preservation solutions organized around three core proprietary technologies: Teretek® (polyurethane resin injection for ground improvement and re-levelling), Terefil® (lightweight cementitious grout for void filling and pipe abandonment), and JOG Computer-Controlled Grouting (precision multipoint cementitious injection for large-scale structural lifting). These technologies address foundation subsidence, settlement, and ground instability across residential, commercial, infrastructure, and mining sectors. Solutions include ground improvement, re-levelling, slab lifting, void filling, and pipe decommissioning. The company operates as a services organization rather than a software platform, delivering engineering solutions on-site to customers globally.
