Stormwater & Drainage in Hallett Cove
Steep, rocky coastal blocks move a lot of water quickly. We design drainage to keep it away from your home.
Local drainage in Hallett Cove
Hallett Cove's geology is well known, but the practical side of it is what matters if you live here: thin soils over rock, steep streets falling toward the coast, and stormwater arriving from uphill neighbours at speed. Split-level homes and benched blocks are everywhere, and every bench is a spot where water can pool if the drainage wasn't done right.
A common local job is a courtyard or patio that floods each winter until a sump and grates give the water somewhere to go. Between the Field River valley on one side and the coastal cliffs on the other, drainage here needs to be designed for slope rather than flat-block thinking.
What we see in Hallett Cove
- Runoff from uphill properties. On sloping streets your stormwater problem often starts a couple of houses up. Cut-off drains, channels, and grates intercept it before it reaches your slab.
- Pooling on benched and split-level blocks. Levelled terraces catch water with nowhere to go. Sumps with pumps lift it back up to street level.
- Thin soil over rock. There's little natural soakage, so surface water has to be collected and piped. Trenching through rock is harder work — we bring the right excavation gear.

Hallett Cove stormwater questions
Water floods across my Hallett Cove patio every winter — can it be fixed?
Yes — this is one of the more common jobs we do in Hallett Cove. The usual fix is a sump cut into the low point with grates to catch the sheet flow, then pumped or piped to the street. There's a before-and-after from a local job on our projects page.
My neighbour's runoff comes onto my block — whose problem is it?
Legally it can be complicated; practically, protecting your home is what matters. Interception drainage along the uphill boundary — a channel drain or cut-off pipe — stops the water before it reaches your living areas, regardless of where it started.
Is excavation harder on Hallett Cove's rocky ground?
Often, yes — the same geology that makes the conservation park interesting sits under many backyards. It changes the machinery and time needed, not whether the job can be done. We quote it up front after seeing the site.
Nearby areas we cover
Sheidow Park
Shares the Cove's slopes, with homes from the late 1970s through the 90s. A recent job here: a dual-pump sump manifold for a block that couldn't gravity-drain to the street.
Trott Park
The same benched-block terrain — levelled terraces that pool water until it's collected and piped somewhere useful.
Marino
Rocky cliff-top streets at the northern end of this stretch of coast — thin soils, fast runoff, and exposed gutters that wear quickly.
