Slope Stability & Landslip Assessment Northland
Got a slip, a cracking driveway or a council stability flag? Gumboots assesses slope stability and designs the fix, with reports councils accept across Northland.
Signs Your Slope Needs an Engineer
- Cracks opening in the ground, driveway or paving
- Fences, power poles or retaining walls starting to lean
- Doors and windows that suddenly stick
- New seepage, springs or boggy ground on a slope
- Bulging or slumping ground below a building
- A council natural hazard or stability overlay on your property
If ground is moving near your house, keep people clear of the affected area and call us.
Why Northland Slopes Slip
Much of Northland sits on clay-rich soils and weathered rock that soften when wet. Long spells of heavy rain, poor drainage, cuts for building platforms and leaking pipes are the usual triggers. We work across Northland, from the Hokianga and the Far North to Whangarei and Kaipara.
Our Slope Stability Services
Stability Assessment
We inspect the site, map the movement and assess how stable the slope is.
Ground Investigation
Test pits, hand augers and deeper testing where needed, to find the weak layer and any groundwater.
Stability Report for Consent
Reports for building consent where council has flagged instability or the site is steep.
Remediation Design
Drainage, retaining walls, re-grading or foundation options to stabilise the slope, with producer statements.
Slips and Insurance
If a slip has damaged your home or the land around it, you may be able to claim through your insurer and the Natural Hazards Commission Toka Tū Ake (formerly EQC). An engineer's assessment helps document what happened and what the repair involves.
