Oil and traffic film removed from concrete, interlock and tiled driveways with a degreaser and dwell time before any pressure is applied.
Oil in porous concrete does not wash off; it has to be lifted out. Pressure alone drives it deeper and pits the surface, which is why blasted driveways look worse a year later.
Degreaser first, given time to work, then controlled pressure with a surface cleaner for an even finish rather than wand stripes.
What the visit covers
- Degreaser applied and given proper dwell time
- Controlled pressure matched to the surface
- Surface cleaner on large flat areas for an even result
- Drainage channels and gully covers cleared
- Garage floors, thresholds and door tracks
- Optional sealing on suitable surfaces
Asked about this
Recent ones usually. Deeply penetrated oil in porous stone often lightens rather than disappears, and we say so before starting.
High pressure blows out the jointing sand. We work at a pressure the surface tolerates and re-sand where needed.
Twice a year for most villas, more where vehicles are parked on the surface.
