Education
A well-designed stormwater system isn’t just about removing water — it’s about protecting every part of your home from the slow, expensive damage that bad drainage causes.
Keep water away from slabs and footings — preventing cracking, movement and costly structural repairs.
Systems designed to capture and discharge storm volumes before they enter your home.
Roof, paved areas and slopes correctly routed to a legal point of discharge — not your neighbour's yard.
Pits and channels stop water pooling on driveways, paths, lawns and pool surrounds.
Subsoil drainage relieves hydrostatic pressure so retaining walls don't bulge, lean or fail.
Compliant drainage protects your biggest asset and removes a major question mark at sale time.

Noah was thorough and addressed our concerns. They booked in our drainage rectification promptly and we are feeling a lot more confident for when the next deluge hits. Highly recommend.”

FAQ
Water pooling hours after rain, a soggy backyard, water against the house or retaining walls, eroding garden beds, overflowing pits, downpipes dumping straight onto the ground. Any of these means your yard drainage is not keeping up. A proper site assessment tells you exactly what is wrong and what it costs to fix.
Yes. Stormwater must be directed to a legal point of discharge under council rules, not onto your neighbour’s block. Every stormwater drainage system we install in Brisbane is council-compliant and certified, so there are no surprises at sale or audit.
Usually, yes. Most backyard drainage fixes are surgical: a pit here, a channel drain there, agi pipe along the wet line. We design around your existing landscaping and reinstate neatly, so the fix does not cost you the yard.
For flooding emergencies we run 24/7 and reach most Brisbane properties within 2 hours. Standard yard drainage assessments are usually booked within the week. Call (07) 3524 0740 and we will give you an honest ETA.
Stormwater carries rainwater from your roof, yard and driveway. Sewer carries wastewater from inside the house. They are separate systems by law, and illegal cross-connections are a surprisingly common cause of the drainage problems we get called to fix.
Yes. Every stormwater drainage job carries our lifetime workmanship guarantee, in writing, on the invoice.
Yes. Brown Arm Boys are QBCC licensed drainers (licence no. 15512139) and fully insured, covering stormwater, yard and backyard drainage across Brisbane and SEQ.
It depends on the size of the problem. A single pit or channel drain is a small job, whole-property flood prevention is bigger. After a site assessment you get a fixed written quote, so the price you approve is the price you pay. Either way it costs less than another wet season of flood damage.
All day, every day. Soggy lawns, bogged-out backyards, water sitting for days after rain: we diagnose where the water comes from, design the fix and install it properly. Your backyard should be usable all year, not just through the dry.
It depends where the water comes from. Surface water wants pits and channel drains, groundwater wants subsoil agi pipe, roof water wants proper downpipe connections. Most Brisbane yards need a mix, which is why we design off a real site assessment instead of guessing.
All of Brisbane plus Logan, Ipswich, Moreton Bay, Redlands and the Bayside. Wherever your yard floods in South East Queensland, odds are we are local to you. Check the service areas above or just call.
