HGM Construction delivers a comprehensive range of slope retention services across New Zealand — from drilling and anchor installation to the full construction of retaining structures using engineered solutions tailored to site conditions.
What sets us apart is our ability to handle sites where access is genuinely difficult. From small excavators and track dumpers to large scale drilling and piling rigs, cranes and HIAB trucks, we have the equipment depth to reach and work on challenging terrain — without clients needing to coordinate multiple contractors.
As a preferred installer for specialist anchor product suppliers, we bring trusted relationships and proven methodology to every project.
We’ve delivered slope retention projects South Island wide and our capability as both a main contractor and subcontractor makes us a flexible and reliable partner for any project.
