The widespread construction of kerbs only
began in the 18th Century despite them having been around since
the days of Pompeii. Originally utilised for the beautification of the city and
to separate transportation from pedestrians, the humble kerb has evolved into
an infrastructure necessity, preventing for example drivers from parking on
pavements and lawns in addition to the provision of structural support for
pavement edges.
Technicrete’s precast Barrier Kerbs have
been successfully installed on numerous regional infrastructural projects
throughout South Africa due to its 100% local manufacture and excellent
quality. The kerb uses the ‘Half-Battered’ profile. This more vertical face
offers a type of ‘barrier’ to motorists for them to be sufficiently aware that
they are dangerously close to the edge. The ‘sloping back’ profile enables road
rollers to operate right up to the edge of the pavement without scratching or
damaging the kerb face when the surfacing is laid.
On slower rural roads the kerb can provide
an element of safety through impact redirection. On fast moving freeways and
highways, the kerb is more often used for drainage and often applied near
bridges, where erosion is a possible factor and to ensure a clear and visible
separation of people and motor vehicle lanes is established.
The Ideal Kerb and Gutter System
A combination of a Technicrete Fig.3
Barrier Kerb and a C900 Gutter Section will convey drain water to the nearest
kerb inlet. Any road resurfacing requirements will not require realignment with
the kerb line either. The Technicrete semi-mountable kerb can also be utilised
in conjunction with the C900 Gutter Section for drainage purposes on roadways
and elsewhere.
The company’s Barrier Kerbs have been
specified for such projects as medical centres, national roadways, private and
commercial residential developments, gutter systems and rural infrastructure
upgrading.
Technicrete and Rocla are part of the
Infrastructure Specialist Group of companies (ISG).
