There is nothing more devastating than a head-on collision between two vehicles travelling at high speed. That is why the opposing lanes on motorway carriageways are separated by a central reservation and crash barriers. Protection is provided by metal guard rails or shaped concrete, or a combination of the two. It must also be provided temporarily when roadworks dictate the use of a contraflow. Using concrete to make roads safer has been the passion of DELTA BLOC International GmbH since 1995, and it is now a synonym for premium concrete barriers across Europe.
