Permeable paving maintenance
The paving can be used immediately. Cleaning using high pressure cleaners and vacuum sweepers is not recommended for the first three months. During this time clean only with a broom or a leaf blower.
The paving needs to be inspected at a minimum of twice a year for defects and spillages. Frequent sweeping and washing reduces the effect of weeds, dirt and grime and maintains the attractiveness of the paving.
Jointing sand maintenance.
The loss of jointing sand in flexible pavements is not uncommon. Sand can be lost via vacuum sweeping and wind or washed out by water movement. It will be necessary, if this occurs, to top up the jointing sand.
Use of chemicals.
Due to the nature of permeable paving systems it is highly recommended that only environmentally safe chemicals be used. The most common use of chemicals on paved areas is the spraying of weeds. Weeds on permeable paving systems should be hand removed or removed using steam.
There are many other common stains that occur on paved surfaces. Such as: • Fungi, moulds and lichens – High pressure cleaning. • Oil, bitumen and tar – Seek professional advice. • Food stains – High pressure cleaning or detergents. • Chewing gum – High pressure cleaning or carbon dioxide aerosol or dry ice. • Tyre marks – Environmentally safe detergents. • Dirt and grime – High pressure cleaning. • Weeds – Hand removal or steam. • Mortar stains – Seek professional advice.
Many of these stains can be removed by high pressure cleaning or using environmentally friendly detergents.
