Drainage Blakehurst: Drains, Sewers and Stormwater Handled Right

New falls, fresh pits, replacement pipe and full re-lays all sit under drainage repair and installation. A knock-down rebuild near the water needs its drainage set out from the boundary connection upward, with pipe sizes and junctions planned around the steep descent.

Older homes get the same discipline. Where a section has collapsed, only the failed length is dug and relayed to a corrected grade. Either way, the layout is designed once, properly, so the line carries what the property actually throws at it for decades, not seasons.

The everyday drainage call: a kitchen, bathroom or laundry backing up, or a gully bubbling at the low corner of a sloping block. The blocked drains page covers the high-pressure water jetting that clears the line and the camera check that follows.

Clearing without diagnosing usually just books the next call-out. The honest answer about whether the blockage was debris or a structural fault is what ends the cycle, and it is on that page.

Sewage surfacing at the lowest gully, or the whole house draining slowly, points well past a single fixture to the main sewer line. The blocked sewer page covers locating the line, clearing it, and rebuilding the boundary joints that settlement on reactive soil has pulled open.

On the older ridge streets, a root-bound clay main can block without warning. Urgent clearing protects finished lower levels before the overflow finds them.

Short, steep catchments dumping straight toward the bays overwhelm older street stormwater during southerly busters and summer downpours. The stormwater page covers rebuilding silted or undersized pits, correcting falls, and carrying surface water away from the house.

On a waterfront block where the land races downhill to Kogarah Bay, the difference between a managed storm and a flooded lower level is usually one well-graded line. That page shows how we build it.

Guessing is the expensive way to fix a drain. A CCTV drain inspection puts the camera through the line and shows the exact fault, its location and its depth, so the quote that follows is for the repair the drain actually needs.

It is the tool that ends the repeat-blockage cycle on clay lines. It is also the evidence you want in hand before spending on any major drainage work, relining included.

Where a line has cracked but not collapsed, pipe relining rebuilds it from the inside: a resin sleeve is cured within the damaged pipe to seal cracks and shut out roots, with no excavation at all.

On a property where the line runs under a rebuilt driveway, a pool surround or mature foreshore planting, relining earns its keep. Reinstating that landscaping would cost more than the repair itself.
