Traffic Paver HydroSTON 80
Suitable for driveways, parking spaces, carparks and low volume residential roads.
Where to use
- Pavements subject to vehicle loadings – vehicles with a gross mass not exceeding 10 tonnes, with occasional use by heavier vehicles
- Residential driveways
- Carparks, parking bays
- Minor roads and access lanes – up to 150 vehicles per day
- Drainage strips
- Watercourse base flow harvesting
- Tree surrounds subject to vehicle loads
- Pavements can be designed for most forms of subgrade, including clay
- High strength and permeability
- Strong edge restraints required
- Laying pattern – herringbone bond
- Generally laid without gap joints
Where not to use
- Steep gradients – infiltration performance decreases with steep gradients during heavy rain events
- Pavements subject to frequent heavy vehicle loading and turning
- Pavement surface less than 600 mm above ground water level
HydroSTON 80 vehicle pavers are specially dimensioned for strength. Widely used for driveways, carparks, parking spaces and laneways.
Standard colours are Light Grey and Charcoal. Other colours can be manufactured to order during scheduled production runs.
HydroCon endeavours to maintain good stocks of standard colours to meet normal customer requirements.
Non-standard colours can be manufactured to order during scheduled production runs of standard colours.
Early lead time advice is required for the manufacture of non-standard colours and customers need to be consulted on colour selection.
Colours shown are a guide only and may vary. Colour samples are available on request.
Gap joints are generally not required with HydroSTON 80 pavements, which are used for light vehicle applications. HydroSTON pavers are dimensionally exact.
When HydroSTON 80 vehicle pavements are to be subject to heavy loadings eg semi-trailers, fire engines or garbage trucks, pavers should be laid with 4mm av. joints to ensure lock up of the pavement and provide flexibility of movement of individual pavers under load. Joints should be filled and compacted with 1-3mm low fines crushed rock.

Pavement and substructure design is relatively straightforward for permeable subgrades and where pavements are intended for pedestrian or light vehicle use. Vehicle pavements however need to be designed not only for permeability but also stability. Substructures for non-residential and high traffic applications should be specified by qualified road or pavement engineers.
Experience indicates that periodic maintenance through brushing, vacuuming or blowing plays a significant role in sustaining open pore structure and good infiltration capacities of HydroSTON pavements.
Periodic cleaning assists in keeping surface voids free of sediment, organic matter and other debris, which if compacted will reduce infiltration performance. Since HydroSTON pavers retain the majority of contaminants close to the surface, cleaning can be carried out either manually with a stiff bristle broom or increasing available wet suction cleaning equipment. Large area pavements can be cleaned mechanically with street cleaning vehicles having sweeping and suction functions. Frequency of cleaning will depend on site conditions ie degree of contamination.
Commitment to an inspection and maintenance schedule (see below) should ensure that HydroSTON pavements continue to perform well for many years after installation. Life expectancy is best expressed in terms of infiltration performance, which in turn is dependent on the maintenance regime applied. Cleaning of poorly maintained pavements with industrial wet suction equipment can restore infiltration capacities to close to original capacities. Ability to restore the infiltration capacity of HydroSTON pavements through in-situ cleaning is a positive and distinguishing feature of HydroSTON pavers.
