Paving cleaning, weed removal & resanding Sandton

Weeds do not grow up from below. Seeds blow into the joints, settle in the sand and germinate. Once the joint sand has washed out, there is more space for soil and seeds to collect. Regular cleaning and keeping the joints full of sand is the best prevention.

Resanding means sweeping fresh, dry jointing sand into the gaps between pavers and compacting it. The sand locks the pavers together so they do not rock or shift, and it stops water and weeds getting into the base. Polymeric jointing sand hardens slightly when wetted and resists weeds and washout for longer. It's always worth getting a professional assessment for your Sandton home.

Yes, when done correctly. Too much pressure or the wrong nozzle strips out the joint sand and can etch softer pavers, so the surface is usually cleaned at a controlled pressure and then resanded afterwards. Sealing after cleaning helps keep stains and moss away.

Moss and algae are cleaned with a pressure wash and a suitable cleaning solution, then the area is kept as dry and sunny as possible. Oil stains on driveways need a degreaser and sometimes a poultice. Persistent black lichen spots may need a specialist cleaner.

Most home paving benefits from a clean and resand every one to two years, more often in shaded or damp areas. A quick sweep and spot weeding in between keeps it looking good for longer.
