Concrete Barriers

Clearway delivers and install BS EN 1317 approved concrete barriers to construction sites, car parks, and vacant properties, preventing unauthorised vehicle access.

If you’re tackling intrusion risks, have security concerns about a festival or construction site, or need to protect a public space from returning travellers, you’ll know that even the best surveillance might not be enough – and you need a tough, impassable physical blockade.

Concrete barrier blocks are a versatile, cost-effective way to create a simple, but extremely robust, perimeter security solution that can be used in a wide variety of applications. 

Whether securing the perimeter of a vacant property, controlling vehicle movement at an outdoor event, or protecting a vacant car park or construction site, our concrete barrier hire service is a quick, efficient and cost-effective solution.

Protect Open Land, Developments, Events and Spaces From Ram Raiding and Vehicular Entry

Concrete barrier hire is a service offering the delivery and installation of Temporary Vertical Concrete Barriers (TVCBs) to secure sites by preventing unauthorised vehicle access.

If you are a construction site manager or are managing a large vacant space, construction site barriers are perfect for preventing unwanted or unauthorised traffic from entering areas that may be unsafe. Construction site barriers can also protect open areas against illegal fly-tipping and unwanted guests inhabiting the land.

Where demarcation is required to determine where vehicles should be driven, concrete road barriers make an excellent temporary solution that is both quick to install and remove after use.

Controlling the flow of traffic in this manner helps protect pedestrians from passing traffic. Due to the sheer weight of the concrete barrier blocks, there is no danger of them being moved either through the actions of drivers or through high winds.

Concrete barriers can also be used to protect workers from passing traffic. When carrying out roadside maintenance, workers are often at risk from road users.

Concrete barriers provide a versatile means of maintaining safety if used as traffic separators during road construction projects.

  • Immovable, solid blocks that stop any vehicle
  • Rapid deployment with delivery often in 24 hours
  • Versatile uses in highways, events and construction
  • Cost-effective solution to myriad security threats
  • Available for short and long-term hire periods
  • Compliant with BS EN 1317 crash standards
  • Fully scalable interlocking system for any barrier length

Temporary Vertical Concrete Block – TVCB Hire


Temporary Vertical Concrete Barriers (TVCBs) are used to provide demarcation and a physical barrier to unauthorised entry. Clearway’s TVCBs are perfect for multiple applications such as securing wide entrances to land or car parks, protecting workers or even providing flood defence. They offer great versatility, serving as both Vehicle Security Barriers (VSBs) and Hostile Vehicle Mitigation (HVM).

 

Purpose-designed to be effective and robust, our TVCBs are manufactured from high-quality concrete and crash tested to withstand high vehicle impact, ideal for protecting road or construction workers and pedestrians.

Safe working environments for construction sites and on highways where workers and the public can be in proximity to high volumes of traffic, TVCBs are excellent traffic protection barriers and for providing perimeter security for private property.

TVCBs

Concrete Jersey Barriers


Jersey Barriers are concrete road barriers designed to protect against high impact. They are ideal for traffic management, specifically separating lanes of traffic, or to protect construction workers and pedestrians in the event of vehicle collisions or crashes into a barrier. 

 

Jersey barriers use an interlocking system so that you can fully secure a continuous perimeter of concrete road blocks at any length.

 

When Jersey Barriers are utilised as edge-protection around perimeters, they offer extremely effective protection against attempted intrusion with vehicles. If traffic rerouting and general traffic management are required during road works or other construction works, Jersey Barriers help to provide a safe environment for workers and pedestrians.

 

Our interlocking Jersey Barriers are manufactured and cast from high-quality concrete. With our lorry-mounted lifting arm and forklift option, they are quick and safe to install on your site.

Jersey Barriers

Interlocking Concrete Blocks


Interlocking concrete blocks are specially designed to stack both vertically and horizontally, creating a retaining wall of any size.

 

Despite their immense weight, they are quick to assemble and easy to install. With excellent fire and water-resistant qualities, interlocking blocks are a robust solution for protecting vacant properties, managing vehicle and pedestrian access or building custom storage bays and partition walls.

 

These blocks are referred to as retaining wall blocks because of the way they allow for secure stacking in any direction to provide solid, highly effective wall structures or barriers that may be required for a wide range of projects.

 

Available in a variety of sizes and weights, our interlocking concrete blocks can have 2, 4, 6, 8 or 10 nodes. These allow for an unlimited range of height, shape and length combinations for anything from storage systems, retaining walls, flood defence or erecting temporary structures.

XL 4700kg Block


Introducing our newest, largest and sturdiest interlocking concrete building block. Crafted with durability in mind, this block serves as a formidable barrier against unauthorised access on vacant sites or during events.

 

As the name suggests, the XL blocks weigh approximately 4700kg (4.7 tonnes) and measure 3.2m in length, 0.8m in height, and 0.8m in depth.

 

It effectively secures access roads, gateways, site perimeters, and industrial entrances.

Additionally, it offers potential application in Hostile Vehicle Mitigation (HVM) measures for events.

 

For added security, these blocks can be stacked as an extra deterrent if necessary. The base features partial forklift truck slots covering 2/3 of its surface.

 

Deliveries, collections, or repositioning are handled by our in-house haulage vehicles, equipped with either a truck-mounted crane (Hiab) or a machinery carrier with a telehandler.

Key Features of Concrete Barriers

    Key Features

    concrete barriers

    Comprehensive Physical Barrier

    We offer a range of concrete blocks in various sizes and configurations, enabling the construction of interlocking formations or the use of extremely heavy-duty blocks for protection against vehicular attacks.

    Immediate and Effective Security

    Blocks cannot be moved or shifted without specialist equipment, which means that a line of barriers provides an instant safeguard and is entirely immovable.

    Proven Compliance With Crash Testing

    The concrete barrier blocks we recommend for roadway projects have been thoroughly tested to the appropriate British standards to ensure they can withstand any impact.

    Adherence to Insurance and Safety Requirements

    Managers of land, events, construction sites, and infrastructure projects can rest assured that they are conforming to all relevant regulations, insurance conditions, and safety standards.

    Scaled or Repositioned on Demand

    If you need to relocate crews to a new zone, require additional blocks, or transition to a new project, we can reposition your barrier using our fully-equipped vehicles, forklifts and cranes.

    How Concrete Barrier Installation Works?

    Advice Around Barrier Sizes and Configurations

    Clearway’s security advisers can recommend the right number, structure and alignment of concrete blocks to meet your safety requirements, whether you need a material storage bay, a road safety barrier, or a security perimeter around an area of land.

    Concrete Barrier Delivery and Erection

    In most cases, we can deliver the required number of concrete blocks within 24 hours, erect them in the desired shape, and ensure we remain updated if you’d like your blockade to be removed at some point or if you’re likely to need to revise the layout.

    Removal or Restructuring

    If you need concrete barriers for short-term use, such as to prevent vehicles from entering a field or outdoor space being used for an event, we’ll pre-plan the collection date, ensuring you can return the site to normal condition as quickly as possible.

    Key Problems That Concrete Barriers Can Solve

    Risks related to serious threats like terrorism, organised crime and ram raiding need fast and effective solutions – and the simplicity of a set of interlocking concrete blocks by no means implies this isn’t a proven way to stop any vehicle, of any size, from bypassing your boundary, entering your site, or accessing live work zones.

    You Need to Stop Vehicles Entering Land or Sites Immediately


    You have open perimeters or boundaries, are aware that forthcoming unrest or protests could spill over onto your land, or have been informed of criminal activity in the area, and you need a fast way to ensure no vehicles can get onto your land or your site.

    You’ve Already Had Trespassers, Fly-Tippers or Travellers on Your Property


    You’ve dealt with the enormous stress of having intruders on your property and need a sure-fire way to prevent anybody from returning, whether it’s an intruder fly-tipping illegally dumped waste from a van, a procession of travellers, or criminal trespassers.

    You Know That Fencing Alone Won’t Stand Up to Determined or Repeated Intrusion Attempts


    You’re concerned about threats and deliberate intrusions, and you appreciate that a fence or wall alone won’t be sufficient to protect your business, premises, staff, or assets from ongoing attacks.

    Your Insurance Provider Expects You to Secure Your Perimeter After a Repossession or Eviction


    You’re managing a site that has been subject to eviction orders and need to put a secure boundary in place quickly to ensure you’re compliant with the terms of your insurance and don’t invalidate your cover.

    You Are Responsible for Protecting Construction Workers and the Public From Traffic


    You have work teams operating on motorways, A-roads, or public access transit routes, and you need to ensure that vehicles cannot enter the space where personnel are working, and to safeguard passers by from HGVs and machinery.

    You Need a Temporary But Immovable Solution While a Site is Vacant, Awaiting Redevelopment or an Event


    You’re planning an event, construction project or other initiative and need a way to ensure your site is completely safe, with zero potential for a successful intrusion, for a short-term period until you’re ready to get started.

    Why Choose Clearway for Concrete Barriers?

    Clearway, a leading UK security company, draws from many years of operational experience to provide effective and reliable site security solutions.

    We can handle a wide range of security needs, from concrete barrier hire to comprehensive security services for vacant properties and construction sites.

    We’re proud to have worked with a variety of industry-leading partners, including water authorities, construction businesses, transport sites, and emergency services.

    Professionally Managed Remote Service for Off-Site Clients


    We often speak with property managers, construction supervisors and landlords who are remote or aren’t able to attend their property in person. In these instances, we may request or help produce digital surveys and photos to ensure we know exactly where and in what quantity a concrete barrier is needed.

    Flexible Hire Periods of Any Duration


    Many organisations require concrete barriers but are unsure how long they will need to be in place, and we are happy to assist. Options include temporary, short-term hire, seasonal installations, or indefinite concrete barrier erection for as many months as your security concerns remain elevated.

    Strong Visual Deterrent Against Intruders


    As we’ve noted, organised criminals may take extreme measures to conceal their identities, including using stolen vehicles which cannot be traced. Concrete barriers are one of the best visual deterrents and provide an immediate signal that access is impossible.

    Options to Integrate Concrete Barriers With Security Gates and Fencing


    If you need to safeguard a site with ongoing access requirements, we can install and recommend anti-climb, anti-tamper fencing, electronic and automated gates, and other access controls that only permit entry to known, verified vehicles and individuals.

    What Do Our Security Experts Say?

    Concrete barriers are a highly effective method of protecting vulnerable areas that may be subjected to terrorist attacks.

    Equally, they can be used to create a secure perimeter following a major incident or terrorist attack. This makes a set of blocks an impressively efficient way to guard against both serious threats and general security concerns.

    Frequently Asked Questions

    How many blocks do I need?


    Concrete blocks are genuinely versatile, and can be erected as individual staggered blocks, as longer fence lines, or stacked to act as flood defences, anti-landslip protection or as material storage bays for construction sites.

     

    If you’re unsure about the quantity or type of blocks you need, please contact the Clearway team. We will review your requirements, arrange a site visit if possible, and provide advice.

    Do you provide site surveys to calculate how many barriers are needed?


    Yes, we can – and it’s very common to be unsure about the exact number of blocks required. To ensure we complete the erection of your barrier in one delivery, it’s advisable to calculate this correctly.

     

    Landowners and business managers who are remote or overseas can also assist with digital surveys and photos of the site, as this can be a quick way to get a reasonably clear idea about the number of blocks we’ll need to dispatch.

    How many concrete blocks can you deliver?


    Individually, our lorries have the capacity to deliver 6 x 2.5 tonne blocks, or 10 x 2.5 tonne blocks with a trailer, at a time. Additional vehicles are engaged for larger installations to coordinate deliveries simultaneously. Fitted with both a hydraulic crane (crane unloading) and an integral Moffett M8 30.3 forklift truck (trailer unloading), we’re able to deliver and position concrete blocks pretty much anywhere.

    Do you offer crane or lorry-mounted barriers?


    We have both options available. In addition to our lorry-mounted hydraulic crane, we use a Moffett M8 30.3 trailer-mounted forklift. The Moffett M8 enables access to hard-to-reach areas, allowing us to supply blocks to most areas of your site, provided the ground conditions are suitable. This forklift can get into places that the crane lorry cannot.

    What concrete barriers do you offer?


    We stock a range of concrete barriers to be used for a number of applications. We will have an initial discussion or site survey to establish your needs and discuss the best solution. Our barriers include pre-cast, temporary, Jersey, interlocking blocks, and barriers with Heras fencing. Our experienced surveyors can pre-empt any potential risks and problems on the site and suggest an appropriate solution.

    Can I contact you 24/7?


    Concrete blocks are typically delivered during a normal working day, although deliveries frequently take place earlier or later in the day to help avoid traffic congestion. Our office is available during normal office hours, but an out-of-hours service is available for emergencies.

    Can you bolt your concrete blocks together?


    Wherever possible, concrete blocks should be positioned end-to-end and bolted together to provide the strongest, most stable barrier. However, bolting blocks together is only possible where the ground is flat and stable enough. In the majority of cases, we will use M24 heavy-duty steel bolts, fitted inside the recesses of the blocks.

    What is the weight of your concrete blocks?


    Our blocks range from 1 tonne to 5 tonnes; however, the standard block we use for the majority of applications is around 2.5 tonnes. When the blocks are bolted together, they become increasingly difficult to move due to the combined weight.

    Do you deliver concrete blocks nationwide?


    Yes, we do. We are based in Kent, in the south east, primarily providing delivery and installation across the south of the UK. Where practical, we will work with trusted partners who comply with our standards and code of practice, delivering and installing concrete blocks across mainland UK.

     

    Our sub-contractors are frequently audited by us, ensuring that each installation is completed to a high standard. As part of our quality control process, we photograph every installation and removal to ensure that we have delivered as per the specification and contractual agreement.

    Concrete blocks can look very industrial and unsightly; do you have any aesthetically pleasing options?


    If you need a concrete barrier solution but don’t want to compromise the aesthetics of your site, we can offer concrete blocks with recesses in which you can place plants. Whilst the functionality remains the same, a planter would soften the appearance of the block and can be used as an aesthetically pleasing yet discreet security measure.

    Will you offer a site survey before the installation?


    Yes. In the vast majority of cases, a site survey can be carried out using Google Earth/Street Map, or clients will send photos to clarify the situation and requirements. As much detail as possible is obtained before installation, as location and final positioning are critical, including the need to know if vehicle or pedestrian access is required. Our team will often spot areas of weakness and assess potential security risks you may not have considered.

    Can I supplement the blocks with gates?


    Yes. Customers often require full perimeter or entrance/exit physical security, but with the ability to allow controlled access for vehicles and/or pedestrians. We supply and install our own, purpose-designed gates, in lengths from 3m to 4.5m, designed specifically to integrate with our concrete barriers. The gates will be delivered and installed at the same time the blocks are installed.
