Trief Kerb

The ultimate in visual and
physical deterrent


The famous Trief Kerb was first introduced to the UK in 1962 and
ever since has made a substantial contribution to traffic control
and safety on our roads.


For highway applications where the
highest level of visual and physical
deterrence is essential, the original
Trief Kerb is the obvious choice. Its
dependability has been demonstrated
repeatedly in use, proving that its
single-unit design is the best available
and significantly increases road
safety.


Multiple uses

Designed for all environments
where the need to contain vehicles
is paramount, the Trief Kerb
delivers proven safety on major
highways, service stations,
warehouses, dockyards and other
areas. The versatile Trief Kerb:

  • Prevents... vehicles from
    accidentally leaving the
    carriageway, encroaching onto
    roundabouts and other areas
    and parking randomly
  • Controls... by forming traffic
    management and calming
    measures such as roadside
    vertical deflections and
    pedestrian refuges
  • Protects... by safeguarding
    verges and landscaped areas
    from vehicle and pedestrian
    incursion, shielding structures in
    heavy traffic areas, protecting
    petrol islands and people and
    parapets on bridges
  • Deters... by creating an
    imposing visual warning that
    prompts drivers to steer away

 

 

High-level safety and practicality

Design 'and
installation

The modular design of the Trief
Kerb makes it simple to install
and use. With over 30 standard
units in the range including
quadrants and radius kerbs, a
huge variety of design layouts
can be created.

Two finishes
The Trief Kerb is available in two
finishes to create the results
required:

Standard Finish: a natural finish                         Textured: with a subtle, slightly
with a smooth matt surface                                   aged finish to complement
                                                                            existing environments such as
                                                                             conservation and heritage
                                                                              locations

The Front Face of the Trief Kerb does not alter the roadside line of standard kerbs, but is built into the footway instead.

Quadrants
A vast range of traffic and petrol pump islands, road junctions and highway seperation points can be designed using the various quadrant units and lengths in the Trief Kerb. External Quadrany are available in 30,45,60 and 90 degree variations, all with radii of 430mm. A 90 degree internal quadrants is also available. The diagrams below illustrate the range of design that can be created using these quadrants.
