Concrete driveway cleaning on Amelia Street, McKinnon. The slab had ingrained dirt and established moss growth, treated with a cleaning solution and cleaned with a surface cleaner.\n\nThe chemical treatment broke down the growth before pressure cleaning, and the surface cleaner attachment gave an even finish across the whole driveway.


The driveway was a concrete slab carrying ingrained dirt and green moss growth across the surface. Moss holds moisture against concrete long after rain, so the pores stay damp and the staining keeps deepening rather than weathering off. In Melbourne's wet months that damp layer also turns slippery underfoot, and once growth is established a garden hose only rinses the surface film while the roots stay in the concrete.
A cleaning solution was applied first and left to work into the moss and ingrained dirt, so the growth was broken down at the root rather than just knocked off the top. The slab was then cleaned with a surface cleaner attachment, which keeps the spray pattern even across the concrete and avoids the striping and wand marks left by free-handed lancing. The result is a consistent finish over the whole driveway.
