Retention System
IPL group’s patented RETENTION SYSTEM is a unique method for installing posts in high-strength RS sockets that builds-on or replaces traditional foundation methods for fast, easy installation and removal of posts.

The RETENTION SYSTEM sets the standard for post installation. It has been designed for a variety of posts, with a range of dedicated RS sockets to match specific post sizes, types and installation requirements. Typically traffic signal posts, signposts, bollards and most street furniture items are installed encased in concrete, or anchored and bolted to a concrete plinth. This means they are permanent and removal entails further expensive, disruptive and potentially dangerous excavation. With the introduction of the multi-use RETENTION SYSTEM these and other posts can now be installed in high-strength RS sockets and replaced with great speed, ease and efficiency.

"The intelligent foundation for post installation"

IPL group developed the RETENTION SYSTEM to meet the rigorous demands and specifications of contemporary urban environments. International standards and post foundation requirements have been considered alongside safety concerns for pedestrian, driver and worker safety in the design and build of each RS socket. The company has a portfolio of innovative products and solutions for a worldwide customer base. Corporate responsibility and sustainability are integral to the way IPL group does business and our focus is on best practices, customer service and international expertise.
The RETENTION SYSTEM range of sockets have been comprehensively trialled, tested and developed on real market experience to meet the crucial challenges facing infrastructure design in this century.
Standards & Specification
IPL group’s innovative and patented RETENTION SYSTEM sets new standards for post installation and intelligent foundation solutions.

IPL group is committed to long-term values in product design, quality solutions, customer service and responsible business practices. As leaders in infrastructure management and maintenance solutions, we have introduced industry standards and specifications for the RETENTION SYSTEM, including the EN124 Standard & CE Mark, in an effort to assist customers with the correct specificaton for installation type and consistent product quality.

The EN124 Standard specifies mechanical tests, classification and minimum product performance requirements. It identifies six product classes with the appropriate class to be used depending on the place of installation. RETENTION SYSTEM sockets are rigorously tested for materials, design, construction, function, dimensions and markings in accordance with the standard and where applicable have appropiate identification of load-bearing class.

The CE marking on cast steel RETENTION SYSTEM sockets documents our compliance with EU Construction Products Regulation (No. 305/2011 - CPR), which is effective throughout Europe and sets manufacturing standards in accordance with European health, safety and environmental legislation. IPL group is the recipient of several awards, including a NISO award for Health and Safety standards. Safety is at the forefront of all our activities and a priority in the design of the RETENTION SYSTEM.
IPL group is a member of The Passive Revolution and signatory in The European Road Safety Charter with a commitment to actions that will reduce road fatalities. The RETENTION SYSTEM is part of our innovative passive safety solutions which focus on reducing the number of fatalities and severity of injury in single vehicle collisions where the driver has crashed into a fixed roadside object. As manufacturer and supplier of street furniture we actively endorse the use of passively safe columns and posts, which break in a controlled manner, absorb energy on impact and are certified to European Standard EN12767:2007.

In addition to product standards, IPL group maintains and operates an Integrated Management System which meets the requirements of ISO9001:2008, OHSAS18001:2007 and ISO14001:2004. This integrated Quality, Safety and Environmental Management System is internationally accredited and is part of our corporate policy of sustainable development and social responsibility.
Research & Design
The RETENTION SYSTEM is designed on extensive market experience and the range of RS sockets continues to develop to accommodate new post types and installation requirements. The RETENTION SYSTEM offers both first-time installation and long-term operational benefits.

The RS socket is first fixed, ready for the post. Once the foundation is in place, the post can be cleanly installed and any required cabling and electrical connections completed. Improved installation and on-site adjustment of depth, direction and rotation is inbuilt on some RS sockets and all installations have the long-term feature of security and easy post replacement.

RS sockets are available in a range of sizes and depths to suit an array of posts, including passive-safe posts, signposts, bollards, traffic signal posts and other street furniture. The RETENTION SYSTEM also facilitates various electrical connections, shallow, deep or reinforced installations, diverse road, surface and environment conditions, and many other user requirements.

In practice the RETENTION SYSTEM works because it separates the integrity of the foundation from the post. This means the foundation and RS socket remain intact beyond the lifespan of most posts, allowing consecutive posts to be installed in the original foundation and RS socket. In overall terms this makes installation, maintenance and replacement of posts cheaper, quicker, safer and easier with the RETENTION SYSTEM.
Benefits
Innovative Products Ltd., a division of IPL group, specifically developed the RETENTION SYSTEM to incorporate many new features and benefits for the complete urban environment.

For all street furniture a good foundation is essential – now a robust, versatile and intelligent foundation is possible. The RETENTION SYSTEM gives choice, convenience and control to those involved in specifying and managing urban environments. Investment in the initial post installation sees immediate advantages. Strong RS sockets improve the reliability and longevity of post foundations and in doing so improve the post and the function it serves. The capital investment and huge reliance on all aspects of the urban environment can be protected. Street furniture can be cleanly fitted and better maintained. Infrastructural posts and traffic control systems can be upgraded or replaced quickly. All post installations in RS sockets deliver significant cost savings and safeguard against disruption, downtime and excavation.

The real benefit of the IPL group RETENTION SYSTEM over other foundation options is its versatility and foresight. Combined with passively safe posts it offers improved road safety for both road users and maintenance personnel. Specifying the use of RS sockets anticipates the expected installation demands, maintenance needs and lifecycle of the post. It also considers the potentially long list of demands on the urban environment, such as repeat post knock-downs, temporary installation or removal of posts for wide loads, seasonal events, security concerns and traffic access control. All these issues are easily managed with the RETENTION SYSTEM sockets for post installation.
