We use a High Speed Vibrating Rotating water jet nozzle to Powerwash which loosens up and removes the Weed, Green Algae & Moss from the surfaces & then we add a Polymeric sand (the next day) which helps bind and strengthen the cracks and squeezes the spacing tighter to help reduce the sunlight and growing of the Weeds etc. from the spacing. Salvaging a driveway using this technique can save you the full cost of a new driveway, which for one client was around $8,000.
