When Drainage Reveals a Structural Problem
If our inspection uncovers issues beyond drainage — foundation movement, ground subsidence, or structural damage — we connect you directly to the right specialists within the Foundations Group.

Drainage failures rarely exist in isolation. Long-term leaks saturate soil, cause clay to expand and contract, and in serious cases create voids below foundations. Our CCTV inspections sometimes reveal that what looks like a drainage problem has already progressed to a structural one.
Drainage Works is a specialist division of the Foundations Group. Our sister divisions are Grace Foundation Solutions, Auckland specialists in foundation movement and remediation, and Geofix®, specialists in ground stabilisation and subsidence repair. Each division does one job at specialist depth. For Drainage Works, that shared experience means we read the ground, not just the pipe: we know what a drain fault does to Auckland clay, and what that movement looks like from the foundation side. And if our camera finds a problem beyond drainage, the right specialists are already in the group. One diagnosis, no re-briefing, no handover gaps.

We inspect your drainage system and document everything we find — including any indications of structural concern.
We talk you through the drainage findings and clearly identify where the concern sits beyond our scope.
We make a direct introduction to the right company — with your CCTV data already shared, so they arrive informed.
Grace Foundation Solutions or Geofix® conducts their own specialist assessment, building on what we've already found.
Where drainage and structural repair are required together, the companies coordinate — so you deal with one plan, not two separate contractors.
Many wall cracks in Auckland homes are cosmetic — hairline settlement cracks that don't indicate active movement. A CCTV inspection is often the most useful first step because it quickly rules in or out drainage as a contributing cause, which in turn informs how seriously a crack should be taken.
Our scope covers everything from standard residential drainage to more complex infrastructure including cesspits, sumps, and stormwater systems. When these connect to structural concerns, we have the right partners to take the job through to completion.
