Long-lasting Concrete Safety Barriers: Thanks to patented Joint Technology


The increasing heavy vehicle traffic, bigger vehicles and severe accidents have already induced many countries to check their restraint systems on motorways or highways.


Concrete Safety Barriers: Safe and Long-Lasting

To this day there is no restraint system which can guarantee stopping a vehicle of any kind, which left the motorway. Nevertheless, concrete safety barriers are the first choice when high containment performance levels are in the foreground. Concrete safety barriers are durable and economically as well as ecologically advantageous. For instance, Austria has been replacing their steel guardrails with concrete barriers for several years now. The demand for concrete safety barriers also increased constantly in France and Belgium.

Precise Joints: Indispensable Requirement

Belgische BSW

Essential factors for building a safe and long-lasting concrete safety barrier are precise joints. Numerous international examples show that without joints, wild cracks appear and cause severe damage on the concrete safety barrier (e.g. complete splitting of the barrier, spalling and relocation).

Wild cracks are a safety risk and require an expensive and time-costly reconstruction of the barrier.

Precise, Clean Joints by CE-Certified Technology

The innovative CCC-machine by the TfB Faber Company is the result of careful development of many years. The phase of development was rounded off by the CE-certification in Ce-logo-tr2010 by TÜV Süd. The user-friendly and compact machine is able to move from joint to joint automatically. The machine is fixed to the joint by clamps without damaging the fresh concrete. The water-cooled joint is performed from above to below to ensure that the joint is not dirtied by created slurries. The wearing of the diamond blade is kept to a minimum due to forced guidance of the cutting device and the constant rotation speed of the cutting drive.


The Crack Control Cutting Machine: Milestone of Work Safety and Precision


Hans-Georg Faber, founder of the TfB Faber Company, located in Binsfeld/Eifel, has more than 30 years of experience in slipform paving. Fifteen years ago, he founded his own company for services around slipform paving with focus on applications engineering. When he watched a worker cutting joints into concrete safety barriers by hand, he could not believe his eyes. Firstly, the job is extremely unhealthy due to fine dust and secondly a precise joint cut by hand is out of question. Since there was no machine which could cut joints automatically, he developed a remote-controlled crack control cutting machine for in-situ concrete barriers. By now, the patented machine has established itself as useful technology. The advantages of the CCC-machine in comparison to dangerous handmade cuts are clear: they offer a high security level (e.g. the fine dust is bound by the wet cutting device). Furthermore, it reaches an unprecedented precision and works time- and cost-saving simultaneously. Thanks to the machine, long-lasting restraint systems, which hardly show any wild cracks, are no longer a fantasy. Due to the compact construction of the machine even constricted hard-shoulders, bridges or gantries are no issue anymore.


Since 2004, the TfB Faber Company has cut more than 340.000 joints into concrete safety barriers on motorways and highways. The efficient machine has proven its flexibility in Germany as well as in France, Great Britain, Slovakia, Belgium and the Netherlands.
