Concrete Barriers

Concrete Barriers for Site Security, Traffic Management and Temporary Works

Concrete barriers are especially popular for use in environments when security is a main priority. The weight of the blocks makes them a formidable barrier. For building purposes, we are also able to supply interlocking blocks and precast drainage products.

HERMEQ is a leading supplier of precast concrete barriers, including crash-tested Temporary Vertical Concrete Barriers (TVCBs), concrete jersey barriers, and concrete security blocks. These concrete barriers are essential for providing effective security and traffic control in construction, event, and high-risk environments. The weight and durability of these blocks ensure they offer strong protection, making them ideal for securing sites and controlling traffic flow.

Which Concrete Barrier or Block Do I Need?

For Site Perimeter Protection

Choose concrete Jersey barriers or concrete security for both long-term and temporary installations, that offer a reliable solution for crowd management, construction site security, and traffic separation. Jersey barriers are ideal for longer lengths of barrier, whereas security blocks tend to be more suited for smaller areas or entrances.

For Temporary Traffic Management

Choose TVCBs, SVEA barriers, PCM/PCH systems or concrete Jersey barriers when a more flexible system is required for vehicle routes, temporary layouts or traffic separation.

For Vehicle Access Control

Choose 2 tonne concrete security blocks where vehicle access needs to be controlled, or the site entrance protected from unauthorised access by vehicles. These blocks are commonly used around compounds, yards, depots and event perimeters.

For Hoarding Support

Choose concrete hoarding ballast blocks when temporary hoarding or fencing needs additional ground support. The blocks should be selected based on the hoarding system compatibility.

For Temporary Support

Choose counterweight concrete blocks when a heavy counterweight is needed for compatible temporary works, site layouts or support applications.

For Modular Block Layouts

Choose interlocking blocks or barriers when you need to form a more structured temporary layout. These can be useful for site separation, storage bays or other temporary works applications.

For Lightweight Barrier Runs

Choose lightweight concrete Jersey barriers where a lighter concrete barrier is needed for a temporary layout. The weight, size, handling and general suitability of the product should be confirmed on the product page before ordering.

Concrete Barrier Types

Concrete Jersey Barriers

Concrete Jersey barriers is an interlocking heavy-duty system designed for the ultimate in anti-vehicle perimeter protection. These concrete barriers are cast using high-strength concrete, making them ideal for traffic management, flood defence, site security and edge protection.The unique interlocking system provides incredible levels of security against unwanted visitors while allowing sections to be easily removed and repositioned should emergency access be required.

Temporary Vertical Concrete Barriers

Temporary Vertical Concrete Barriers, shortened to TVCBs, are ideal for creating safe working areas for your workforce and preventing un-authorised access to private land. They are also used as traffic barriers and to help direct traffic flow as they are crash tested.TVCBs are also used as concrete vehicle security barriers, concrete vehicle containment barriers, hostile vehicle mitigation concrete barriers.

Concrete Security Blocks

Concrete security blocks are purpose-built to maintain the utmost security and are equipped with their own lifting and placing systems. This ensures a seamless installation process, allowing you to establish a reliable barrier swiftly and effortlessly.Precast security blocks are largely used to prevent trespassing as they can be used across entrance ways.

Concrete Hoarding and Ballast Blocks

Concrete hoarding blocks and ballast blocks compatible with traditional timber hoarding and steel hoarding panels. Ballast Blocks are used to increase the strength of the hoarding system and subsequently increase the wind loading the hoarding system can withstand.Choose these products where the main requirement is hoarding support, not vehicle impact protection.

Counterweight Concrete Blocks

Counterweight concrete blocks are used to increase the wind loading of temporary and permanent steel and timber hoarding systems.

Interlocking Concrete Blocks

Interlocking concrete blocks are high-strength and durable blocks that interlock to aid and provide support for a wide variety of projects. Made from high-quality precast concrete, these blocks have been thoroughly monitored to ensure all density, dimensional accuracy and compressive strength are tested on a regular basis.

How to Choose the Right Concrete Barrier

Application

Start with the job the barrier needs to do. For traffic separation, look at concrete traffic barriers, TVCBs, Jersey barriers or dedicated temporary traffic systems. For site security, choose concrete security blocks or Jersey barriers. For hoarding and fencing support, choose compatible ballast or hoarding blocks.

Vehicle, pedestrian or site separation

Concrete barriers can be used to delineate routes, control access and create a visible boundary, but not every concrete barrier is a crash barrier or vehicle restraint system.

Weight and handling

Concrete barriers and blocks can vary significantly in weight. Consider if the site has suitable forklift, lifting clutch, crane, or other offloading arrangements available. Heavy concrete products should be planned carefully before delivery.

Installation requirements

Some temporary barrier systems may need specialist installation or approved contractors to meet stated compliance requirements, and our team can help with that as well. Do not rely on the category page alone for installation details. Use the individual product page and any available specification sheets before placing an order.

Layout and connection method

For long runs or continuous barrier lines, check whether the product interlocks, connects, stacks or aligns with other units. For standalone access control, a concrete security block may be more suitable than a longer barrier. For hoarding or fencing, compatibility with the panel, post or support system is more important than barrier length.

Visibility and finish

Some concrete barriers may be available in painted or coloured options, while others may be supplied in a standard concrete finish. Painted or coloured options can support visibility, site zoning or route control.

Common Uses for Concrete Barriers

Construction Sites

Concrete barriers are widely used on construction sites to separate working areas, control vehicle routes, protect site entrances and create clear boundaries around restricted areas. They can also support temporary layouts where standard plastic or steel barriers may not provide enough mass.

Roadworks and Traffic Management

Concrete traffic barriers, TVCBs and temporary barrier systems can be used to guide traffic, separate work zones and support temporary road layouts.

Depots, Yards and Industrial Sites

Concrete security blocks and Jersey barriers are practical for depots, logistics yards, industrial estates and storage areas where vehicle access needs to be managed. They help define routes, block unauthorised access and protect restricted zones.

Events and Public Access Areas

For events and areas open to the public, concrete blocks shall be used in those situations where a more permanent boundary or access-control measure is needed.

Hoarding, Fencing and Temporary Works

Concrete hoarding blocks, ballast blocks and counterweights can support temporary works where added mass is required. These products should be matched to the compatible fencing, hoarding or temporary works system rather than chosen only by weight.
