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).

Rebloc’s integrated noise barrier: various materials and colours are available as sound absorption material
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.

    Concrete barrier expert REBLOC has developed REBLOC 100SFP_8, a powerfully flexible barrier system for new bridges as well as for bridge refurbishment. Tested freestanding, the barrier achieves containment levels H2 with working-width W3 and H4b with W5. It is also possible to achieve H4b with W4 by using an additional position securing system. The safety concrete barrier is part of the REBLOC SWITCH product line which enables the use of the same system as either a temporary or a permanent barrier. All s

    Rebloc says that its barriers with narrow working widths and high containment levels provide the lowest dynamic deflection to ensure minimum movement during an accident. As only limited space is available on a construction site, a low working width of the barrier is crucial. The aim is to maximise the room for traffic movement at the same time as construction operations. The working width of temporary barriers is determined by the width of the system plus its dynamic lateral movement in the event of an ac
