Precast Kerbs

Durable Exposed Aggregate Kerbing for Footpaths and Traffic Medians

Description

Produced in a special exposed aggregate finish, SVC’s range of precast concrete metropolitan kerbs offers a visually appealing alternative to traditional concrete kerbing poured on-site during construction. Specified in the City of Melbourne’s standard drawing package, SVC precast kerbs have been deployed in the CBD and surrounding suburbs for many decades.

Our precast kerb units can be used in various roadside applications including footpath edging, nature strips, traffic medians and garden beds. Our metropolitan kerbs are available as straight or curved units with multiple radii on offer, supporting a variety of traffic island configurations.

Compared to a standard in-situ kerb installation which features a plain, off-form finish, SVC’s precast metropolitan kerbs are produced in a shot-blasted exposed aggregate finish, which adds a layer of design complexity and interest. Precast concrete kerbs also possess superior strength properties than in-situ kerbing due to the controlled manufacturing process, which is conducted in a protected environment away from outdoor elements. The high-strength 40MPa concrete in our precast kerbs ensures their long-lasting durability, and the uniformity of each unit creates a seamless finish post installation.

Features & Benefits

  • Consistent, uniform design that is much more visually appealing than standard in-situ concrete
  • A variety of straight and radial kerbing units allows multiple design configurations
  • Robust, hard-wearing material that endures for decades in the outdoor built environment

Material Specifications

  • Produced from 40MPa high-strength, steel-reinforced precast concrete
  • Features a shot-blasted textured finish that reveals large fragments of bluestone aggregate

Frequently Asked Questions

Can you incorporate colour or reflective markings into precast kerbs?

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.

How do you join the sections of precast kerb?

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.

Are different kerb shapes and profiles available?

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.

What is the advantage of precast kerbing over pouring on-site?

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.
