De Bonte Group already simulated with the REBLOC® Safety Barriers concrete transitions to the most common systems in the current Belgian market. The successful simulation between our systems and the in-situ barriers poured on site means we know perfectly how they perform and will behave in the event of a collision.

Within our REBLOC® range, De Bonte Group always takes care of the installation so that everything is done as per regulations and the right placement instructions. Anchoring is can easily be done by the contractor but De Bonte Group will also offer a solution for this when needed.

Measurement results are available and should be submitted to the client.

The REBLOC® sound barrier consists of a concrete Jersey with HEA profiles. The profiles can then be simply placed on our Jersey barrier in the classic way, analogous to how they would be placed if no concrete Jersey were present.

The REBLOC® H2 system combined with sound barrier consists of a 1m high Jersey and a 1m high sound panel made of wood fibre concrete, with the remaining 2.5m built up in a material of your choice. For our H4b system, a 1.5m-high Jersey should always be installed in combination with a 1m-high wood-fibre concrete sound panel. The remaining 4m can be constructed from a material of your choice. De Bonte Group will also support you in calculations regarding tipping hazard under wind loads specific to your conditions.

Certainly, in the design phase, De Bonte Group will always ask you to provide a DWG file. At this stage, we prepare drawings, which need to be approved by the management/contractor. During this phase, De Bonte Group also considers whether or not fitted pieces will be needed. These are also produced locally and quickly.

At a time of such high fuel prices and when ecological thinking is increasingly important, it becomes all the more important to use temporary barriers as a permanent system later on. This is to minimise the supply and removal of guide structures. REBLOC® therefore tested many of their REBLOC® systems at T3 level and released them under their range Switch. A great overview (including Technical Sheets) can be found via following link: https://www.rebloc.com/en/switch-temporary-permanent/.

The 4 main parameters to determine the type of guide structure are: The retaining capacity, the operating width, the vehicle slope and the surface on which they are eventually placed.  At De Bonte Group, you can always ask for advice during the preliminary design if you are in doubt when determining one of these 4 parameters. Based on the Dutch handbook ‘Vademecum vergevingsgezinde wegen (VVW) part motorised traffic’ and the existing solution, we will then determine with you the optimal solution for your particular situation.

The ultimate goal in existing or yet-to-be-designed tunnels is that you always want to use as much width as possible. To provide a solution to this, REBLOC® tested a very slim model that, in conjunction with the tunnel wall, passed a perfect crash test at H2 level. More info can be found via following link: https://www.rebloc.com/en/eco-permanent/. You will then find the info under “Free standing system in front of rigid wall” and the Technical Sheet “RB80XW_8_H2/W1”.

De Bonte Group is in close contact with suppliers of steel guardrails so that the steel-concrete transitions already approved by COPRO can be applied to the wide range of systems. In addition, De Bonte Group continues to innovate for additional transitions to steel crash barriers in order to be able to offer a wider range of solutions within the Belgian market in the future.

De Bonte Group has 2 in-house installation teams with the appropriate equipment. Moreover, De Bonte Group is fully preparing for the imminent requirement regarding the new performance certification of safety barriers as per PTV8004-1.
