Drainlayer in Parnell

Lift the agreed surface area and keep reusable paving separate from excavated spoil. Dig progressively to expose the pipe rather than working solely from a mark on the courtyard. Check its material, condition, depth, direction and nearby branches. The repair needs sound pipe at each end, not just access to the visible break.

The exposed condition determines whether we repair a joint or replace a damaged length. New pipework needs compatible connections, suitable bedding and support through the repair. Check levels and alignment onsite before fixing the arrangement. For restricted drainlaying, use an appropriately authorised person and check their authorisation through the PGDB register.

Before work begins, establish the consent position for the actual repair using MBIE guidance. Excavation close to public wastewater pipes also needs a check against Watercare's asset protection process, as approval may be required. Resolve these matters while planning access, rather than after the courtyard has been opened.

Build testing and any required inspection into the programme while the repaired pipe remains visible. Check the completed joints, alignment and flow through the repaired section using the testing appropriate to the work. Arrange required inspection before covering the pipe. Give the paving contractor a clear release point instead of booking reinstatement around an unconfirmed backfill date.

Photograph the exposed repair and record its position against fixed courtyard features. Keep details of the pipework, connections, tests and any inspection documentation with the handover information. The owner or builder should receive a record showing what was repaired and where it sits beneath the finish.

Backfill protects the repaired pipe and prepares the opening for the agreed surface work. Confirm who replaces bedding, resets paving and finishes joints. At handover, identify completed surfaces, outstanding reinstatement and any materials retained for that work.
