Weed Seed Control
Wind blows weed seeds everywhere. Seeds settle inside jointing sand between pavers rather than pushing up from the deep earth below, so brushing the surface with a stiff broom every month stops root growth cold across driveways in Brent before sand washes away.
Engine Oil Stains
Motor oil penetrates unsealed stone. A dripping sump leaves dark marks that absorb into mineral pores quickly, requiring immediate application of dry cat litter or specialised degreaser paste directly over the driveway stain before rain washes grease deeper into the block.
Pressure Washing Warnings
High water pressure strips sand. Blasting the surface with an industrial power washer removes essential joint aggregate, causing blocks to shift sideways over time, so using a rotary flat-surface cleaner at lower flow keeps blocks seated firmly while rinsing away autumn moss.
