Building in confidence with the Tensartech TW1 Wall System
Tensar Technology - provenpractical solutions and theknow-how to get them built
Tensartech systems are based on Tensar Technologyand the proven performance of Tensar geogrids. TensarTechnology is widely adopted for ground stabilisationproblems and reinforced soil structures, delivering realsavings in cost and time. We can help you apply TensarTechnology to deliver the best value on your project.

The Tensartech TW1 Wall System consists of pre-castconcrete modular facing blocks in combination withTensar geogrids which reinforce the soil mass behind.The high efficiency connection between facing unitand geogrid is a distinctive feature of the system,creating strong and durable, maintenance freeretaining wall structures.
Factory produced concrete blocks made to exactingstandards and close tolerances together with the high-density polyethylene (HDPE) geogrid reinforcementprovide resilient permanent retaining walls and bridgeabutments which will perform for design lives of up to120 years.
Continual research in the laboratory and in the fieldhas provided a detailed understanding of thebehaviour of this type of structure. The strength of theconnection between the geogrid reinforcement andthe block facing has proved to be critically important.
The distinctive geometry of the concrete facing blocksallows the creation of both internal and external curves.Corners, stairs and other features are easily detailed.
The high pH associated with concrete blocks does notaffect the durability and functionality of HDPE geogridreinforcement during the life of the structure.
Often no specialist skills are required to install theTW1 concrete blocks and Tensar geogrids.
Specially designed corners and copings produceattractive structures.
A feature common to all Tensartech Wall Systems isthe high efficiency connection between geogridand facing unit, which is quick and easy to install.
Tensartech TW1 Wall System for proven construction of retaining walls and bridge abutments
The cost effectiveness and versatility of the TensartechTW1 Wall System offers clients, specifiers and contractorsmany advantages over other traditional methods, such asreinforced concrete, for the construction of retaining wallsand bridge abutments:
Rapid and economical construction
Attractive range of modular block,finishes and colours
Durable and maintenance free
Often no specialist construction skills necessary
Tolerance of differential settlement
Adaptable to provide aesthetic architectural effect
Optimises the use of available space
High resistance to earthquake loading
Possibility of using site-won or recycled granular fill materials
Low bearing pressure may avoid expensive foundation treatment
This project in the UAE demonstrates that the Tensartech TW1 Wall Systemcan be built without cranes or propping.
Construction of demanding highways structures with a 120 year design life.
Independent assessment and approval
Offering cost effectivenessand versatility
Savings of up to 50% over conventional constructionmethods such as reinforced concrete can be achievedby constructing with the Tensartech TW1 Wall System.In addition construction time may also besignificantly reduced.
Both the TW1 Wall System and Tensar RE geogridshave been awarded British Board of Agrément (BBA)Roads and Bridges certificates allowing their designand specification in to highways structures and bridgeabutments with a 120 year design life. The BBAcertificates are evidence that both the TW1 System andTensar RE geogrids have been evaluated independentlyfor fitness for intended use.
Unsurpassed experience and reliabilityTensar International is the world leader in geogridtechnology and the provision of high performancereinforced soil solutions, with over 25 years experience.Many thousands of reinforced soil structures, in manyvaried geotechnical and climatic conditions, have beendesigned and built using Tensar Technology around theworld.
