Tensar International's Tensartech System is said to provide an integrated solution with a wide choice of aesthetic masonry block finishes, backed by reliable support services and new software. This is especially important where earth retaining structures are specified for embankments, bridge abutments and slopes on infrastructure, urban and landscape schemes, The company tells Building Products that the attractive finished appearance can be specified to meet local planning requirements, and Tensartech TW1 and TW3 Wall Systems offer cost savings up to 50 per cent, with considerable savings in construction time, over conventional reinforced concrete retaining methods.
Tensartech says its solutions are highly durable (with a design life of up to 120 years) and BBA certification and are now even easier to specify and introduce into a project, by utilising Tensar’s model specifications. New Tensartech TW1 and TW3 Wall Systems brochures introduce the elements of the Tensartech solutions and emphasise their many advantages in specification, installation and finished appearance.
Rhondda Cynon Taff Council's engineers are using Tensar International's ground stabilisation solutions to repair a partial landslide with site-won material in the Rhonnda Valley.
Stabilising an old landfill in Danylan, close to Pontypridd, has challenged RCT engineers since 2004. Upon completion the Tensar design team demonstrated that stabilisation of the slope could be achieved using geogrids.
The A66 Carkin Moor to Scotch Corner project involves upgrading the original single carriageway to address safety concerns.
Where differential settlement is threatening a remodelled junction, Tensar's TriAx geogrid is providing an additional dimension of stability, saving design and build contractors Balfour Beatty Regional Civil Engineering the time and costs inherent in conventional remedial solutions and meeting the Highways Agency's key performance indicators..

To create bridge abutments, wing walls and steep embankments Tensar International's Wall System and geogrid technology has been used at the Barnhalt Bridge project in Belfast. The geogrid was fastened with connectors to the dry laid Tensar TW3 split faced cast blocks on the bridge wing walls and abutments. 50m embankments were produced on either side of the railway.
Utilising Tensar Technology, a structural solution for a helipad at Lancaster Hospital was achieved. Using the company's geogrids, a steep grass structure was created, connected to a steel mesh panel face.
In using geogrid reinforcement, the helipad is considered an earth embankment rather than a retaining structure and therefore avoiding regulation implications.
The face is formed using steel mesh panels with turf laid behind to blend in with the surrounding scenery, The platform is built up using granular fill reinforced with the company's RE geogrids. The construction requires no formal foundation with no special skills or tools.
Some 20 Tensar employees, who have celebrated 20 years or more service, have been presented with an engraved watch by the company chief executive officer, Jim Paul, at the firms recent reception to thank long serving employees.
The awards went to people from all sections of the company, including process operators and quality control staff working at the Shadsworth site factory and customer services and marketing employees based at Mill Hill.
Flood risks from the adjoining Shutterton Brook at Dawlish Sands Holiday Park in Devon have been overcome by a cost-effective solution from Tensar International. The solution comprises a reinforced soil retaining wall and reinforced embankment, providing upgraded defences to meet the Environment Agency 1 in 100 year flood prevention standard. Two reinforced soil embankments act as earth bunds on either bank of the brook, using Tensar RE geogrids.
Allowing access space for the new facilities and access road at the redevelopment of Aintree racecourse, Laing O-Rourke has adopted a Tensar Wall System (TWS) to create a retaining wall. Following demolition and site preparation at the racecourse, a lead time of just ten weeks was available to get reinforced concrete walls designed, specified and started on site. As an alternative, the Tensar Wall solution was specified which was completely installed on site in eight weeks. The solution comprises dry laid wall of Tensar concrete blocks, 70m long and between 2m and 4m high. The fill behind the wall is completed with imported granular material stabilised by layers of Tensar uniaxial geogrid. This geogrid is connected to the blocks with the company's polymer key, so that the whole provides an integrated load bearing structure.
Despite unfavourable weather and saturated soil conditions, an ambitious highway building programme in Hungary is continuing thanks to Tensar SS biaxial geogrids.The geogrids provide full access to the site for heavy plant, enable vertical drains to be installed and ensures a reinforced base for the embankment on which the highway is constructed.
Asphalt reinforcement from Tensar International has been used on the runway of Woensdrect military airport in the Netherlands. Both the Glasstex P50 and Tensar AR asphalt reinforcement were used to control reflective cracking. Glasstex gives optimum reinforcement, while AR is more suited to control cracking above flexible pavement sections.
