Older homes in Riccarton and Fendalton, 1940s to 1960s subdivisions in Ilam, Avonhead and Burnside, homes beside industry in Hornby and new subdivisions at Wigram. Drainage is the part of a build nobody sees once the trench is filled, and the most expensive part to get wrong. A fall that is too flat blocks, a joint that is badly bedded cracks, and a connection in the wrong place fails inspection. In Christchurch there is an extra layer: the ground itself, which ranges from liquefaction-prone land with high groundwater in the east to Port Hills rock in the south.
Drainlaying in West Christchurch: relays in Fendalton, new connections at Wigram
West Christchurch gives drainlayers two very different job lists. In Riccarton, Fendalton and Burnside the homes are older, sections are established and large trees are common. Here we relay laterals damaged by roots or age, add drains for extensions and connect new infill homes where a large section has been split. A camera inspection first shows how much of the old line can stay in service.
Burnside's post war group housing from the 1950s and 1960s often has one original line serving the whole house. When an owner renovates a bathroom or adds a second one, that line may need upgrading or rerouting. Ilam has family homes and student rentals around the University of Canterbury, where landlords usually want a repair done quickly with minimal disruption to tenants.
Wigram and the western edge are about new building. Wigram Skies and The Runway were subdivided on the former aerodrome after it closed in 2009, and smaller subdivisions such as Broken Run sit near the headwaters of the Heathcote River. Hornby adds commercial and industrial sites beside the Sockburn estates, where trade waste pre treatment may be needed under the Trade Waste Bylaw 2025. All drains are laid to clause G13, consented and inspected by Christchurch City Council, and we supply as built plans so the layout is on record for the property. In Fendalton and Riccarton, where established gardens surround the drain, we plan the trench route with you to spare as many trees and beds as we can, and use pipe relining where it avoids digging altogether. Around Ilam, work in rental homes is timed with the landlord and tenants so bathrooms are out of action for as short a time as possible.
Local tip: On a Fendalton relay, ask us to map where your trees sit relative to the new line, because a small change of route can avoid future root trouble.

Pricing: quotes are free, and every job gets a fixed price before we start, so there are no surprises on the invoice.

Drainlaying West Christchurch FAQs
We are converting a Riccarton house into two flats. Will the drains need upgrading?
Usually some work is needed. Each unit may need its own connection or a larger shared line, and the consent sets the requirement. We camera the existing drain and design from there.
What is an as-built plan?
A drawing of where the drains were actually laid. The council needs it to sign off the work, and it saves time for anyone who has to find the drains later.
How do I find out if my section is TC2 or TC3?
The technical category is shown on the property's LIM and on the council's land maps. We check it before we quote because it affects foundation and drainage design.
