The extruded technique allows to curb road or highway works
for security or rainwater runoff purpose
the screw extrusion technique
lack of available information, main contractors,
project managers and purchasing advisors
don't sometimes have enough information
about concrete pouring techniques and joined
now distinguish 2 main techniques for concrete
extrusion : Pouring by vibration or by screw.
each other, these 2 techniques allows to
pour road and highway works as well as industrial
areas and some other works.
techniques answer to different features
and get their own benefit.
curb by vibration
technique need slipform machines guided
for high and direction by string and sensors.
This kind of guidance allows to work on
a lot of base if it can be drive on, without
caring of road irregularityuntill almost
machines, most bigger than the Curbilder
(c) using screw, don't allow you to pour
on all kind of works, specially in circulation.
Radius should be not less than 5 meters
to provide good works.
could be productive for high curbs. This
productivity can only be aim if you solve
guide position problems, separated pieces
works and concrette supply.
curb concrete and asphalt with screw curb
technique needs smaller machines and take
less working place on the road, so it is
able to curb minimum 60 cm curves.
machines follow the base which is most of
the time made of asphalt, so it as to be
well done to ensure the best quality of
work event if it is possible to plan it
before working, if necessary.
machines allows to pour a lot of different
curbs as : I, T, A, GSS2, mini GBA, ...,

concrete plant, which is normalize, guarantee
the concrete features regarding the strength.
If country is concerned, concrete provided
by the concrete plant will fit to European
EN 206-1 standard or it national equivalent.
unnaturally cracks when water disappear.
This unpredictable crack can get accept
for some works. For some others, due to
aesthetically pleasing reasons it as to
be canalize. It is why joints are made.
joints can be done either on fresh concrete
during pouring, or on "young"
concrete by sawing at a special time during
it solidification. It has to be done through
special process in both cases.

repairs are usally simple. If works is enough
long (more than 10 meters long ) a working
team is able to come back to re-curb this
part of the works. If it is shorter, curb

technique main assets
concrete extruding technique brings a lot
of assets to curb road or rainwater sewer
system, regarding to traditional method
(prefabricated or form curbs).
ADVANTAGES, because it allows to curb high
quality works at full capacity (hundreds
of meters per day)
ADVANTAGES, because it technique allows
to curb curves and circles and to pour various
finishing touches by changing looking and
colours of works.
ADVANTAGES, because it is recommend by working
and health organizations, regarding to back
illnesses due to prefabricated curb work.
ADVANTAGES, due to a carbon footprint which
looks better than other traditional methods.
