Foundation Repair in Christchurch
Cracked, sinking, or uneven foundation? We diagnose the real problem and fix it right — built to handle Canterbury’s ground conditions for good.
Your foundation carries the weight of everything above it, which means even small problems below the surface can eventually show up as cracked walls, sticking doors, or uneven floors throughout your home. Christchurch’s seismic history and variable soil conditions make foundation issues more common here than in many other parts of New Zealand, and they rarely fix themselves.
We assess, diagnose, and repair foundation problems using proper engineering practices, not surface-level patches. Whether you're dealing with settling, cracking, liquefaction-related shift, or damage from historical seismic activity, we get to the root cause before recommending a repair plan, so the problem doesn't resurface a few years down the line.
Signs You Need Foundation Repair
Not sure whether what you're seeing is serious? Here are common warning signs:
- Visible cracks in foundation walls or slabs
- Doors and windows that stick or won't close properly
- Uneven or sloping floors inside the home
- Gaps forming around window frames or door frames
- Cracks appearing in interior walls or ceilings
- Driveway or exterior slab pulling away from the house
- Standing water or pooling near the foundation
- A noticeable “bounce” or give in flooring
If you're seeing one or more of these signs, it's worth getting it assessed before the damage progresses further.

Christchurch Foundation Repair Questions
How do I know if it's a foundation problem or just normal settling?
Minor settling is common in most homes, but cracks wider than a few millimetres, doors that suddenly stick, or sloping floors usually indicate something more serious. A professional assessment can tell you for certain.
Will insurance or EQC cover my foundation repair?
It depends on the cause and your specific policy. We provide documentation and assessments that align with typical EQC and insurance claim requirements, and can advise on next steps.
How long does foundation repair take?
Timelines vary based on the extent of damage, from a few days for crack injection to several weeks for full underpinning or re-engineering work.
Do I need to move out during repairs?
In most cases, no. Foundation repair work is typically done from the exterior or in isolated areas, minimising disruption to daily life.
What causes foundation problems in Christchurch specifically?
Variable soil conditions, historical seismic activity, and liquefaction risk in certain zones are the most common contributing factors in this region.
