Building with bricks

The following recommendations deal with vehicles and associated equipment and their use:

  1. High Pressure washers should not be used on clay brick, as they remove the surface which will result in deterioration over time.
  2. Equipment should be purpose designed to sweep the particular area. If there is any doubt, the vehicle manufacturer should be consulted.
  3. Tyres should be inflated according to the manufacturer’s recommendations to ensure maximum weight distribution.
  4. Polypropylene, not wire, brushes should be used.
  5. Sweeping brush pressures should be set to the minimum required to suit the particular task, i.e. surfaces swept regularly will require a lesser setting than those swept infrequently or those covered with heavy deposits.
  6. When sweeping, engine revolutions should be set at the minimum required to maintain vacuum (suction) pressure.
  7. Operators, including reliefs, should be trained to vehicle manufacturer’s recommendations and tyre and brush pressures should be regularly checked.
  8. Advice should be given to operators that, when equipment is stationary or left unattended, suction, brush rotation and water jetting equipment should be switched off to avoid the risk of damage to the area below the stationary equipment.
  9. In new or re-laid areas, agreement should be reached with the local Highways Authority to allow the pavement to settle and the joints to seal before manual cleaning.
  10. When water jetting equipment to wash such areas is used, the jets or hand held lance should be directed at the surface at an angle not greater than 30o and across the diagonal (i.e. not parallel to joints) using a suitable detergent solution.
  11. The area should be inspected after cleaning to ensure that joints are refilled with jointing sand if necessary.
