Jet washing is beneficial for tarmac,presscrete, concrete, indian sandstone and other patios for several reasons. Firstly, it effectively removes dirt and grime that can accumulate over time, restoring the original appearance of the surface. This is particularly important for tarmac driveways or patios that are exposed to heavy foot traffic or vehicles. Secondly, jet washing can help prevent the growth of moss, algae, or weeds on these surfaces. By removing these organic materials regularly, it reduces the risk of slips and falls due to slippery surfaces. Lastly, jet washing can prolong the lifespan of tarmac and patios by removing contaminants that can cause deterioration or damage over time.
