Drainage on the Gold Coast
Drainage That Stops the Wet Patches
When water sits where it should not, the whole yard can feel like hard work. Coastline Earthworks provides drainage trenching and site preparation across the Gold Coast, Logan and Brisbane, helping homeowners, landscapers and builders set up reliable stormwater and drainage runs.
We excavate clean trench lines for pipes and pits, shape the base to support the install and keep spoil managed so access stays safe and tidy. With tight-access machines we can work in confined side passages and backyards, making it easier to fix problem areas without tearing the place apart.

Frequently Asked Questions
How do I know if my yard has a drainage problem?
Common signs include water pooling after rain, soggy patches that never dry, soil erosion, muddy side access and damp areas near the house slab. You may also see water flowing back towards structures instead of away. Checking surface falls and downpipe discharge points helps pinpoint where water is being trapped.
What is the difference between stormwater drainage and yard drainage?
Stormwater drainage usually refers to pipes and pits that carry roof water from gutters and downpipes to a legal discharge point. Yard drainage can include surface grading, spoon drains and subsurface systems that collect groundwater from lawns or garden beds. Both rely on correct falls and clear flow paths.
Why does drainage trenching need a fall?
A fall creates gravity flow so water moves through the pipe instead of sitting in low points. If the trench base is uneven, water can pool, carrying sediment that leads to blockages over time. Consistent grade also helps pipe joints stay aligned and makes backfilling and compaction more reliable.
Practical Falls & Neat Trenching
Good drainage is about more than digging a channel and hoping for the best. The trench needs consistent depth, sensible fall and a stable base so the system can be laid correctly and backfilled without movement.
We plan around existing ground levels, likely flow paths and where water needs to go, then excavate with control so the next stage is straightforward. For residential sites, keeping trenches neat also reduces reinstatement time across lawns, garden beds and paved areas.
If you are linking new drainage into other works like earthmoving, turfing preparation or retaining walls, doing it in the right order saves a lot of rework later.
