New Case Study! - PARAFENCE™ FOR HORTICULTURAL APPLICATIONS

FEBRUARY 2015

Linear Composites Ltd is pleased to announce the publication of a new PARAFENCE™ case study. The case study focuses on the use of PARAFENCE™ at the Rathfinney Vineyard in Alfriston, East Sussex, England.

In this application PARAFENCE™ acts as a windbreak to protect juvenile grape vines from cold sea breezes which travel down the valley. PARAFENCE™ acts to reduce the wind speed to which the juvenile grapes are exposed to and thus reduces the effect of the cold sea breezes, this is expected to increase crop yields over the coming years.

In total this installation consists of 3.2 linear kilometres of PARAFENCE™ installed over an areas of 12,800 square metres.


PARAFENCE™ is supplied to the global market and has been installed in large scale windbreak projects including the Coquelles Channel Tunnel Terminals and The Narbonne Sports Stadium. Other applications for PARAFENCE™ include horticultural shade halls and snow and particulate control fence systems.

Linear Composites Ltd specialises in the design and installation of the PARAFENCE™ windbreak system, for 'routine' and bespoke applications. If you are working on a project in which PARAFENCE™ could be of use please contact our design team by clicking this link.

Long Term ParaFence™ Case Study

DECEMBER 2014

Linear Composites is pleased to announce the publication of an long term case study for PARAFENCE™ supplied to the Channel Tunnel project in 1992. A single panel of fence was replaced recently during works on third party infrastructure. This gave the chance the perform physical testing on a PARAFENCE™ panel that had been in constant service for over 20 years.

The case study in question features the original supply and installation of the PARAFENCE windbreak system between the platforms of the vehicle loading terminal. The replacement works allowed the opportinity for a in-situ condition assessment of the fence followed by physical testing. The testing showed that despite being under constant load for over 20 years, the fence material had undergone no loss in performance when compared to quality control tests done on the original material when it left the factor nearly a quarter of a century before.


PARAFENCE is supplied to the global market and has been installed in large scale windbreak projects including the Folkestone, Coquelles, and Calais Channel Tunnel Terminals and The Narbonne Sports Stadium.

New Case Study! - Muscat Express Way

January 2011

In 2006 VSL Middle East were awarded the tender to construct 108,000 m2 of MSE retaining wall on the Muscat Southern Expressway. The Muscat Expressway was completed in mid 2010 and is a divided dual carriageway which runs parallel to the Sultan Qaboos Highway. The total length of the main highway is 53km with an additional 112km of cross roads and service roads.


VSL Middle East’s design Engineers determined that the optimum solution was to build the MSE retaining wall using the VSoL® Polymeric Walls System; PARAWEB<sup>®</sup> and PARALOOP<sup>®</sup> are integral components within this system. 30, 50 and 70kN PARAWEB<sup>®</sup> strips were used as the reinforcement material while 70kN PARALOOPs were cast in to the concrete facing panels as an anchorage system.

{img src="media/news_story_6_image2.jpg" alt=""/}

PARAWEB<sup>®</sup> and PARALOOPs were chosen by VSL Middle East for these applications due to the combination of their excellent physical properties, high durability and high resistance to environmental and chemical attack.

Indian Factory Completed

December 2010

Due to increasing global demand for the unique, high-quality PARAWEB<sup>®</sup> and PARALINK<sup>®</sup> soil reinforcement products, Linear Composites Ltd has completed the commissioning of a state-of-the art production facility in Pune, India. This complements the existing facilities in Yorkshire, UK. The new facility Maccaferri Environmental Solutions Pty Ltd (MESPL) has been awarded the ISO 9001:2008 Quality Management Standard and doubles the available manufacturing capacity of these ranges of products for Linear Composites Ltd.

Commercial Director, Steve Miller said “This brand new facility allows us to be more responsive to the demands of the global market through increased capacity and reduced shipping times. In this era of austerity, we seem to be bucking the trend by selling more of a high quality product, rather than the opposite.”

{img src="media/news_india.jpg" alt=""/}

PARAWEB<sup>®</sup> and PARALINK<sup>®</sup> are high performance products for soil reinforcement applications. Featuring polyester strength elements, sheathed in a robust polyethylene sheath, the products offer the best long term design strength reduction factors in the marketplace today. Steve Miller adds: “No other geogrid comes close to this performance. PARAWEB<sup>®</sup>was first used in Department of Transport projects in 1977. This is a long pedigree and customers are confident of the quality of our products in their demanding projects, particularly major infrastructure and mining works where the high loads and aggressive conditions require high performance sheathed geogrids, rather than the lighter-weight woven or extruded grids.”

PARAFIL® types F and G stand the test of time

November 2010


34 years ago Linear Composites Ltd erected an external test rig and suspended PARAFIL<sup>®</sup> type F 3 tonne (NBL) ropes under constant loads of 1200kg (40% NBL). From this point until present we have periodically measured the creep strain of the ropes in conjunction with the Industrial Fibre department at DuPont®.

Over the period of this test the creep strain characteristics of PARAFIL<sup>®</sup> type F and G ropes surpassed all expectations. The measured creep over the duration of the test is 0.23%, this works out at a strain rate of 0.035% per decade. Assuming that the PARAFIL<sup>®</sup> ropes continue to creep at the same rate we have calculated that the ropes will not fail for another 992 years.

{img src="media/news_parafil_test.jpg" alt=""/}

Long term creep tests in their nature are inconvenient, spanning decades! In the rope industry it is standard to model creep behaviour on the results of accelerated age testing. Long term creep models give a reasonable understanding of creep strain behaviour but are only an approximation and are no substitute for actual test data. Our test results prove the long term performance of PARAFIL®, giving design engineer’s confidence when selecting PARAFIL<sup>®</sup>ropes for projects with a long design life.

It is our understanding that this is the world’s longest continual rope test.
