This Compliance article is written for Melbourne owners and managers who need more than a quick blast. Commercial Pressure Cleaning jobs in our city require a surface diagnosis before any cleaning starts.
In Melbourne, everything from growth corridor new-build mortar smear to inner-suburb heritage brick has its own cleaning risk profile. The right method, chemistry and pressure keep the surface safe and the result lasting.
Know where the water will go
Walk the site and mark street pits, yard gullies, basement drains and low points. Doncaster slopes, inner-terrace camber and basement ramps all send water somewhere. Cleaning without that map is guessing.
Controls that actually work
Drain mats and socks, temporary bunding, wet-vac recovery and controlled disposal to an approved point are the usual toolkit. Choose controls for the chemistry in use — brick acid rinse and bin-pad grease are different loads.
Residential does not mean exempt
Homeowners and small contractors still face neighbour complaints and council attention when foamy water hits the gutter. Plant beds are not a free disposal zone either; rinse discipline protects landscaping and compliance together.
Commercial and strata expectations
Managing agents increasingly ask for photos of containment in place. Method statements for shopping centres and OC sites should name the drains and the control for each. Audits are uncommon until they are suddenly not.
Weather and timing
Starting a chemical clean minutes before a forecast downpour can overwhelm bunds. Build a weather check into the day plan. Winter drizzle that never quite stops may mean smaller staged zones rather than whole-site wetting.
What clients should ask
Where will rinse water go, what mats are used, and what happens to recovered liquid? Vague answers correlate with vague other practices. Clear answers belong in the written scope before arrival.
On the job
- Melbourne stormwater pits are not for detergent or oily wastewater.
- Identify every grate before the first chemical mix.
- Mats, bunds and vacuum recovery are standard controls — not optional extras.
- Sloping sites need staged barriers, not hope.
Common questions
Are drain mats enough on every site?
Not always. Steep drives and heavy chemical loads may need bunding and vacuum recovery as well — the control must match the site.
Does residential cleaning need containment too?
Yes. Detergent and contaminated rinse water should not be sent to the street drain on homes any more than on commercial sites.
