Rebloc wins in Estonia with its noise barrier NB100/300_8_H2/W4

Rebloc’s integrated noise barrier offers maximum noise protection while creating a highly effective noise barrier and vehicle restraint system. Rebloc says that its system meets the highest safety and quality standards and is tested according to European Standard EN 1317 (vehicle restraint system), EN 14388 and EN 1793 (noise barrier).

8751 Rebloc’s integrated noise barrier offers maximum noise protection while creating a highly effective noise barrier and vehicle restraint system. Rebloc says that its system meets the highest safety and quality standards and is tested according to European Standard EN 1317 (vehicle restraint system), EN 14388 and EN 1793 (noise barrier).


The main advantage of the noise barrier system is the combination of a vehicle restraint system as a concrete safety barrier with an integrated noise barrier. It features a space-saving slim design – the reason that it was chosen for installation in Estonia last autumn. There was not enough space for a conventional design including a regular guardrail and noise barrier.

Around 400m of single-sided noise barrier NB100/300_8_H2/W4 has been installed on motorway 4 – also known as the pan-European E67 -  near Tallinn-Pärnu-Ikla. Project managers were particularly satisfied with the easy installation of the system and that construction was finished ahead of schedule, according to Rebloc.

The system features a modular construction consisting of a concrete base and a noise barrier panel that is inserted into the slotted recesses of two concrete elements providing a form-and-force locked connection.

A full-length continuous steel tension bar is integrated into the barrier elements and connects them with the integrated coupling to form a strong and continuous chain. The coupling system has no loose parts, which facilitates the installation and prevents unauthorised removal of pieces.

Due to the modular construction, the system can act as a temporary noise barrier.

Rebloc’s noise barrier is available as a one-sided system for use along the verge of the road as well as a double-sided system for the central reservation. The noise barrier can be customised to accommodate heights, containment levels and application-specific designs. Various materials and colours are available as sound absorption material.

    Barrier and crash cushion systems can make a great deal of difference to roadway safety, with new technology offering major benefits to road users. In North America and Western Europe, concrete centre line dividers are being used for many major highways as these provide a durable solution for preventing cross-over accidents with large vehicles such as heavy trucks. It is worth noting too that other countries are now adopting concrete barriers for highway centre line dividers also, with this system being use

    Barrier Systems says that its new tensioned barrier offers high energy absorbing capabilities in head-on collisions. The company says that this is because the X-Tension technology is a tension-based solution rather than compression-based. The new range delivers good performance in these applications, as energy is absorbed with resistance at the impact head rather than being transferred down the rail as occurs with other systems. Even high-angle (15° during testing) impacts on the nose resulted in the vehicl
