DELTA BLOC® is a modern and advanced system of concrete barriers, designed to ensure maximum safety on roads and highways. This system combines a robust construction, effective deformation properties and simple assembly, which makes it an ideal solution for various traffic situations. Thanks to unique technological innovations, DELTA BLOC® offers reliable protection and a significant increase in safety.

Materials and construction:

• Concrete barriers: Parts of the NEW JERSEY profile, designed for impact resistance. Thanks to the continuous drawbar, it is secured, that it will not break even with a strong impact. The special design reduces the kinetic energy during a collision by creating an additional deformation zone.

• Fasteners: Push-in couplings and mounting holes ensure a solid connection of the parts, thereby contributing to the stability and efficiency of the system. The individual elements are designed so, to be easily assembled and disassembled.

Implementation and assembly:

When installing DELTA BLOC® concrete barriers, care must be taken to properly comply with all building regulations. Individual parts are usually installed directly from the truck using a crane arm. After placement, they are connected using special galvanized connectors, which form a continuous link – the heart of the entire system. This process guarantees quick assembly with minimal disruption to operations.

For the maximum effectiveness of the retaining wall, it is necessary to install the parts in a minimum length 32 meters including the outer parts. It is recommended to place the pieces like this, so that the locks are in a tensioned state, which prevents horizontal displacements and increases the effectiveness of barriers.

Using the Delta Bloc® system:

• Motorways and expressways: Effective separation of traffic lanes and protection against vehicles leaving the road.

• Communication with high traffic density: Ideal for places with a high frequency of vehicles and an increased risk of accidents.

• Dangerous places: Use in bridge piers, protective zones of water sources and areas threatened by landslides or falling rocks.

• Construction zones: Temporary protection of workers and traffic management during construction works.

• Flood protection: Protection of areas prone to flooding.

Certification and quality:

DELTA BLOC® meets the highest safety standards according to the European EN standard 1317 and is approved by the Ministry of Transport of the Czech Republic for use on all types of roads. The products are certified according to ČSN EN ISO 9001:2009 a ČSN AND ISO 14001:2005, which guarantees their high quality and reliability.

IZD road panels are flat reinforced concrete elements of rectangular format designed to create temporary or permanent paved surfaces. They are used for temporary purpose-built communications, parking and storage areas, but also for permanent class III communications. a IV. order. Their main advantage is easy and quick assembly and, if necessary, disassembly.

Materials and construction:

• Concrete classes: C 25/30 or C 30/37, depending on load and environmental requirements.

• Degree of environmental influence: XF3 (pro C 25/30) a XF4 (pro C 30/37), which ensure resistance to frost and aggressive environmental influences.

• Steel reinforcement: Grade steel used 10 505 (R) or CURRY (W) ensures high strength and durability of the panels.

• Dimensions and types: IZD road panels are available in various thicknesses and sizes. They have thicknesses 15 cm or 21,5 cm and are produced for different loads. They make it possible to create roads with different traffic loads - for vehicles weighing up to 6 again (wheel load 21 kN) or until 20 again (wheel load 50 kN).

• By mutual agreement, special road panels can also be produced according to the customer's specifications
  (shape and dimensions, class of concrete, reinforcement etc.)

Use of IZD road panels:
