Traffic Management

SVC's precast kerbing range - including traffic median kerbs, spiked kerbs, wheel stops, bike separator kerbs and speed humps - is produced in our standard high-strength concrete mix, supplied in an industrial grey concrete colour. This provides a clean blank canvas that allows the client to paint, stencil or add reflective markings to the kerbing products for applications where high-visibility is required.

SVC's precast bike lane separator units are designed to be installed 125mm beneath the road surface, which sets them deeper into the road, adding extra stability and preventing displacement. The units should be lifted into place using lifting clutches that can be connected to the steel lifting anchors that are cast into the top surface of each unit.

Each bike kerb unit can be connected to the adjoining unit using 13mm dia dowel connectors, inserted into the unit's dowel voids. A high-strength epoxy adhesive can be used on the base of each unit to create a secure bond with the surface beneath, though this is not a mandatory step.

Opting for high-strength precast concrete kerbs creates a solid barrier that offers genuine physical protection, thanks to the material's excellent performance in the outdoor environment and its resistance to degradation, wear and tear. They are a resilient, long-lasting asset in comparison with other materials such as plastic or rubber kerbing options, which are easily damaged upon vehicular impact and require frequent replacement.

The kerb sections are laid end-to-end on a prepared flat base made from concrete, crushed rock or a mortar bed. The edges of the units are butted up together and can be joined with or without adhesive. As they are designed to be installed slightly lower than the road surface, the surrounding asphalt reduces the likelihood of the kerbs moving around.

SVC's most popular option for precast metropolitan kerbs is our distinctive 300x200 barrier kerb profile, which is listed on the City of Melbourne design specification. This kerb profile is available in a variety of different sizes i.e. 1m straights and multiple radial options.

Other kerb profiles are also available, such as 200x200, 300x300 and 500x200 profiles - these options are much less popular and have fewer varieties compared to the 300x200 range.

Compared to forming up concrete kerb on-site, installing precast kerbs offers superior quality control and reduced installation time. In-situ kerb installation requires time and labour to prepare formwork, pour and shape concrete on-site, plus a minimum of 24-48 hours for the kerbing to set and dry after installation. In comparison, precast kerbs are delivered to site ready for immediate installation and do not require any further curing time after installation.

Thanks to the controls of a factory manufacturing environment, precast kerbs are often stronger in compressive strength than in-situ concrete. They also exhibit a visually appealing exposed aggregate finish made possible by the shot-blasting of the kerb units during manufacture. All work is completed at the factory prior to installation, meaning the kerbing units arrive on site ready to install as finished products.

The wheel stop is placed in the correct position, and holes are drilled through pre-formed voids into the pavement below. Galvanized steel spikes are then driven through the unit into the ground.

Typically, standard practice requires one wheel stop centred in each individual parking bay.

Concrete wheel stops are significantly more durable, vandal-resistant, and do not degrade or become brittle from UV exposure. They provide a more robust, long-term solution for any high-traffic car park.

The modules are supplied as individual units that are placed in sequence and securely fixed on a concrete or mortar base, slightly beneath the finished road surface. Asphalt is then used to fill in any gaps around the speed hump. This approach enables better security and rigidity, ensuring low possibility of speed hump movement upon impact.

They are ideal for private roads, commercial car parks, and industrial estates where a permanent and highly durable traffic calming device is required to ensure pedestrian and driver safety.

Opting for high-strength precast concrete speed humps offers genuine, lasting protection and performance, thanks to the material's excellent performance in the outdoor environment and its innate resistance to degradation, wear and tear. Compared to plastic, rubber or asphalt speed humps that easily deteriorate and deform over time when subjected to frequent traffic and extreme weather conditions, concrete speed humps are a much more reliable material, offering resilient, long-lasting performance and low ongoing maintenance requirements.
