Benefits for Pavers and Walkways
The Doff Integra system uses superheated steam reaching temperatures of 120-150°C (248-302°F) at low pressure, delivering precise cleaning without chemicals or abrasives that damage delicate residential surfaces. This makes it ideal for interlocking pavers, concrete walkways, flagstone paths, and brick driveways on Vancouver Island homes, restoring their original color and texture while preventing slip hazards from moss buildup.
Unlike pressure washing, which only dislodges surface growth and leaves spores behind, Doff Integra penetrates porous materials to kill organic matter at the root. The superheated steam instantly vaporizes lichen and moss cells, denaturing proteins and destroying reproductive spores that would otherwise regrow within weeks—ensuring longer-lasting results, often 12-24 months without re-infestation in our coastal climate.
How Superheated Steam Targets Lichen and Moss
Lichen thrives on shaded, moist pavers by forming crusty patches that etch into the stone, while moss spreads fuzzy layers that retain moisture and accelerate deterioration. Doff Integra's steam blasts these at over 100°C, causing:
-
Cellular rupture: Heat expands moisture inside lichen hyphae and moss protonemata, bursting cell walls in seconds.
-
Spore sterilization: Fungal spores and moss gemmae (reproductive units) are thermophilic up to 60°C but die instantly above 100°C, preventing regrowth even in damp microclimates.
-
Deep decontamination: Steam infiltrates joints and cracks up to 50mm deep, eliminating black spores that pressure washing scatters but doesn't kill.
As a home or business owner, you'll see your walkways return to a clean, uniform look with no residue, and the process is safe for nearby plants, pets, and groundwater.
Long-Term Residential Advantages
On residential sites, Doff cleaning extends paver lifespan by removing biofilm that traps salts and causes spalling, while the dry steam leaves surfaces ready for immediate use—no puddles or runoff. For heritage or interlock walkways, it preserves mortar integrity better than acidic moss killers, and repeat treatments are rarer, saving time and cost over chemical maintenance.
