A Jersey barrier, or Jersey wall, is a modular concrete barrier employed to separate lanes of traffic. Jersey Barrier is designed to minimize vehicle damage in cases of incidental contact while still preventing vehicle crossovers resulting in a likely head-on collision. Jersey barriers are also used to reroute traffic and protect pedestrians and workers during highway construction. Blocking access – whether this jersey barrier is to a property, commercial premises or plot of land, the weight of a concrete jersey barrier renders it almost impossible to breach. This makes concrete systems the optimum choice for long-term jersey barriers to entry and access points in order to:

Jersey Barriers prevent trespass and intrusion.

Jersey Barriers reduces risk of harm from attacks which use vehicles, such as ram-raiding.

Jersey Barriers optimise safety from additional hazards, for example by keeping public and vehicles at a safe distance from debris or specific hazards, such as dangerous structures, landslides or deep water.

Jersey Barriers prevent issues such as fly-tipping as access cannot be gained to do so.

Blocking view following accidents or during works, sometimes the sight of a site can be a significant distraction to nearby road users and communities, whilst jersery baarier may also be necessary to screen works for other privacy or protection reasons.

Guiding traffic whilst other types of jersey barrier systems can also be used for guiding traffic the advantage of concrete systems, particularly Jersey barriers, is that their significant weight and stability means they are not easily dislodged by vibration from transport systems – including trains, and traffic

Bay boundaries as well as guiding traffic, Jersey barriers can also be used to effectively create and delineate parking and storage bays.

Defences the increased stability of concrete jersey barriers such as Jersey barriers, and the highly interlocking qualities of Legato systems mean that these types of concrete barriers can also be used defensively, for example to support works by retaining earth. These jersey barriers may also be deployed as part of flood defences, as the fully interlocking design means that no additional mortar, which would be vulnerable to wear in wet conditions, is required to install the defence.
