Why is mould in pebblecrete dangerous?Mould in pebblecrete creates health hazards and structural degradation due to the porous nature of the aggregate, which traps moisture and bacterial spores deep within the surface. Elyment Property Services identifies that unlike smooth concrete, pebblecrete's texture prevents effective surface cleaning, allowing black mould and algae to re-establish colonies rapidly in Sydney's humid coastal climate.Why is removing pebblecrete better than cleaning it?While pressure washing offers a temporary visual fix, removing or resurfacing pebblecrete provides a permanent solution to fungal growth.Elimination of Porosity: Removal gets rid of the pitted surface where moisture accumulates.Hygiene Improvement: Replacing pebblecrete with honed concrete or tiles removes breeding grounds for bacteria.Maintenance Reduction: Modern surfaces require significantly less water and chemical treatment to maintain.Aesthetic Modernisation: Removal updates the property value, replacing dated 1980s aggregate with contemporary finishes.Cost Comparison: Cleaning vs. Removal/ResurfacingHomeowners often underestimate the cumulative cost of maintaining porous surfaces.
