Common Reasons You May Need Drainlaying

Drainage system upgrades for renovations and extensions

Drain connections for kitchens, bathrooms, laundries, and wet areas
Site-specific drainage designs for difficult terrain

What’s Involved in Professional Drainlaying?
Drainlaying is more than just digging trenches and laying pipe. Our certified team follows a clear process:
Planning & Design – We assess your site and project requirements to create a compliant, efficient drainage plan.
Excavation & Installation – We carry out trenching and lay sewer and stormwater pipes to NZ building code standards.
Inspection & Testing – Every system is pressure-tested and council-inspected before sign-off.
Backfilling & Site Restoration – Once approved, we carefully backfill and restore the site.
We handle everything from start to finish, so you don’t need to coordinate multiple contractors.
