Wellington's specialist retaining wall and slip repair team.
Wellington's terrain is unlike anywhere else – complex geology, steep hillsides, and some of the most challenging sites in the country. We've built the specialist expertise and the equipment to ensure it's done right.
Specific expertise to meet the unique demands of Wellington
Wellington's unique landscape is defined by greywacke rock, steep hillsides, and a complex network of underground waterways – all of which shape how and where slips occur, and how they need to be repaired.
Understanding that geology isn't optional; it determines everything from anchor placement to drainage design. We've spent over 20 years working across Wellington's hills and valleys, and that local knowledge is built into every repair we do.
What Wellington's ground teaches you
The ground changes fast
Wellington's geology is unpredictable in ways that aren't visible from the surface.
Within a few meters you can encounter solid Blue-rock, next to that highly dilated fractured open rock and then in the next hole completely weather sandstone.
All this within 3 or 4 meters. Knowing how to deal with changes like that efficiently only comes from experience that you just can't shortcut.
The city goes deep
There are parts of the Wellington region where you can be 100m above sea-level but, when drilling you encounter millennia old marine clays.
Add fault lines, seismic crush zones to the mix and you have Wellington.
Only experienced specialists now how to deal with these situations efficiently.
The sites are tight
Wellington is a city built on hillsides. Many older homes sit so close to the bank behind them that standard equipment simply won't fit.
It's why we've designed and built our own specialist drilling rigs – so we can reach the places others can't.
The expertise for the most challenging land reconstruction projects
Tight, difficult-access sites are a hallmark of Wellington. So we built equipment and expertise to work in these environments. With our expertise in anchor-based retention systems, foundation drilling, and slip repairs ensures that we can tackle even the most challenging projects.
