Visit RHE24 / DEXTRA booth at the Australasian Tunnelling Conference (ATS 2020+1) on May 10-13, 2021 at booth no. 57, Melbourne Convention & Exhibition Centre (MCEC), Australia.

We are pleased to invite you to our live webinar on “Headed Bars Design According to ACI 318”, presented by Richard Goodman, Technical Manager, Dextra Europe, on Wednesday, 28th April, 2021 from 3 to 4 p.m. (GMT+7).

The webinar will introduce the basis of how to design with headed bars in accordance with ACI 318 principles, as well as giving practical advice and information about their use.

With over 25 years of experience in the design of steel products for construction, Richard will share his knowledge and insights on how your can apply the FRP rebar to your next construction projects.

We are pleased to announce that Dextra India offices in Mumbai and Chennai have been relocated, in order to provide an even better service to all our customers.

A Dextra America lançou um sistema de tubo sônico projetado por “push fit” feito nos EUA para testes de concreto Crosshole Sonic Logging (CSL). Os tubos Sonitec facilitam o teste de integridade de fundações usando o método de teste CSL e estão em conformidade com a ASTM D6760. Os tubos Sonitec CSL são projetados especificamente para testes CSL e fornecem uma solução mais segura e rápida quando fixados em gaiolas de reforço.

A Sonitec vem em dois modelos diferentes, o Sonitec Plus e o Sonitec Slim. O Sonitec Plus é composto por tubos de aço Schedule 40 de 2” com uma extremidade alargada em formato de boca de sino para conexão instantânea: permite uma instalação de encaixe rápida e fácil. É produzido em conformidade com o padrão AASHTO (Associação Americana de Oficiais de Rodovias e Transportes Estaduais).

O Sonitec Slim apresenta um design mais leve, com uma espessura de parede mais fina de 0,49” e um diâmetro de 2”, resultando em redução de peso superior a 70%. Ele também apresenta o mesmo design “push fit” para instalação rápida e fácil.

Ambos os modelos são testados e qualificados nos EUA e excedem a pressão de 725 psi por um minuto.

Apesar de ser uma adição recente ao portfólio de produtos da Dextra America, os tubos Sonitec CSL são confiáveis em trabalhos há mais de 20 anos e são a solução preferida para empilhadores e empreiteiros gerais em todo o mundo. A Sonitec economiza tempo e trabalho em campo e oferece uma solução segura e rápida para um ambiente de teste CSL perfeito.

A Sonitec agora é orgulhosamente fabricada nos EUA com aço dos EUA, portanto, em total conformidade com as leis Buy America e Buy American.

Glass Fiber Reinforced Polymer (GFRP) solutions are frequently used for several applications in civil engineering due to its many benefits compared to alternative, conventional materials:

A 1/4 of the weight, but 2x stronger in tension compared to steel rebar

For corrosive resistance in acidic and alkali environments

Ideal for temporary applications

Suitable for permanent applications

In mining and tunneling this composite technology has successfully been used for decades, and GFRP is now also available for soil nails and tieback ground anchors.

A perfect showcase of latest GFRP solutions available is the Melbourne Metro Tunnel project, a major enhancement to Melbourne’s rail network: a multibillion-dollar project comprising the design and construction of twin nine-kilometer tunnels and five underground stations.

Dextra supported the project team with its technical expertise on GFRP at design stage and manufactured the GFRP solutions as per the project’s requirements:

ASTEC GFRP Combination Bolts were used as temporary measure to secure the center walls of the 19m wide caverns of the two major CBD stations during construction of two conventional 7m tunnels, built in parallel. Easy removal after completion enabled faster construction progress.

GFRP Astec soil nails secure the stations walls under construction. Some of the anchors are located outside the boundary of the project and can remain in the ground as material properties allow for easy cutting at later stage via commonly used excavation equipment.

GFRP ASTEC Soft-Eyes enabled disruption-free penetration of the Tunnel Boring Machines (TBM) through the thick concrete diaphragm walls of five stations. No demolition equipment needed, and no workers required to access the shaft to guarantee the maximum level of safety and efficiency.
