REBLOC

REBLOC is a precast concrete vehicle restraint system designed to provide protection on high speed roads. There is a wide range of REBLOC products designed to suit all locations and applications ranging from normal to very high containment and low working widths. The individual elements form a high strength continuous chain that safely absorbs energy and impact forces. Technically advanced, all REBLOC safety barriers are tested to EN 1317 to ensure suitability and performance for road projects. With key safety features and benefits, as well as versatility, REBLOC is an outstanding choice for any highways related scheme. What Is REBLOC? Barriers with a minimum design life of 50 years are mandated for permanent use in England on central reserves of roads with high traffic volumes. The REBLOC concrete vehicle restraint systems (VRS) are precast products that allow for rapid deployment across the strategic road network. The off-site manufacture also eliminates wet trades on-site, reduces the risk to the workforce with shortened installation times and is immediately operational with no curing time required. Ranging from normal containment to very high containment, our full suite of both permanent and temporary concrete VRS are tested to EN 1317 and are CE marked. Our precast systems are the product of choice for main contractors as the requirement for off-site manufacture increases.

Works Safety Gate (WSG)

With increased focus on worker safety across the UK road network, Hill & Smith Infrastructure, in partnership with Balfour Beatty – Vinci JV, have developed the Works Safety Gate (WSG) to greatly reduce the danger faced by road workers when adjacent to works access points. Developed with both the approved Varioguard and Zoneguard temporary vehicle restraint systems, the WSG further raises the bar when considering the safety of road workers and the travelling public at the necessary works access points required within major road work schemes. A typical 48 m length WSG installed at a works access point, can be opened manually by removing the securing pins at 8 m centres and separating the WSG into manually manageable lengths, providing access to works vehicles and subsequently closing using the same methodology maintaining a secure and safe environment at all times during the works. Features No connections or transitions required – The design of the WSG is such that it can be deployed against any vehicle restraint system with no connections or transitions required. High visibility – The highly visible red and white powder coated sections of the WSG clearly define the access points within the works presenting clear delineation for works vehicle drivers. Quick joints – The WSG is unique in the fact that existing road worker professionals can be trained by Hill & Smith Infrastructure instructors to operate the system safely and when necessary, which means that access to the work site can be arranged at short notice in a controlled and extremely safe manner. The WSG is part of the unrivalled suite of products on offer from Hill & Smith Infrastructure and, working independently of the installed VRS, are available in a multitude of lengths from 48 m to 168 m for any planned or existing works throughout the National Highways network.
