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.
Dextra America has launched a US made “push fit” designed sonic tube system for Crosshole Sonic Logging (CSL) testing of concrete. Sonitec tubes facilitate the integrity testing of foundations using the CSL testing method and are compliant with ASTM D6760. Sonitec CSL tubes are designed specifically for CSL testing and provide a safer and quicker solution when secured in การเสริมแรง กรง
Sonitec มีสองรุ่นที่แตกต่างกัน ได้แก่ Sonitec Plus และ Sonitec Slim Sonitec Plus เป็นท่อเหล็ก Schedule 40 ขนาด 2 นิ้วที่มีปลายขยายใหญ่ขึ้นเป็นรูปปากระฆังเพื่อการเชื่อมต่อได้ทันที: ช่วยให้ติดตั้งแบบกดพอดีได้ง่ายและรวดเร็ว ผลิตตามมาตรฐาน AASHTO (American Association of State Highway and Transportation Officials)
Despite being a recent addition to Dextra America’s product portfolio, Sonitec CSL tubes have been trusted on jobs for over 20 years and are the preferred solution for เสาเข็ม and general contractors worldwide. Sonitec saves time and labor in the field and offers a safe and quick solution for a perfect CSL testing environment.
ขณะนี้ Sonitec ผลิตขึ้นอย่างภาคภูมิใจในสหรัฐอเมริกาด้วยเหล็กกล้าของสหรัฐอเมริกา ดังนั้นจึงสอดคล้องกับ Buy America และ Buy American Acts อย่างสมบูรณ์
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.

Dextra held a seminar on building construction technology with Bouygues-Thai on Friday, September 18, 2020 at Dextra Manufacturing office and factory in Bangkok, Thailand.
The one-day seminar featured innovative precast element connection technology, tension and compression bar systems, crosshole sonic logging testing method, a technical detailing training and a factory visit.
These are extraordinary times, creating unique obstacles and unexpected opportunities for ports professionals around the world.

CURRENT CHALLENGES AND FUTURE OPPORTUNITIES FOR PORTS AND SHIPPING IN ASEAN
Thursday, September 24, 2020
10.00 to 11.30AM (CEST)
The webinar features prestigious panelists in the port and shipping industry of Indonesia, Malaysia and Philippines, along with Dextra experts in port expansion solutions.
Dextra is showcasing innovative ground engineering solutions, featuring GFRP ซอฟท์อายส์ และ Rock-Bolts, at the World Tunnel Digital Congress (WTC) 2020 on September 14-16, 2020.
WTC is one of the world’s leading tunneling event that explores the latest innovations, trends and advances in all areas of tunneling, from tunnel project development to both design and construction.
The event is moved to a fully digital platform due to the impact of COVID-19: it will include online technical paper presentations, along with training courses, and virtual exhibitions by companies from all over the world.
Dextra features a wide range of underground temporary and permanent support solutions, with a focus on cuttable glass fiber reinforcement polymer (GFRP) technology: join us at the virtual exhibition at booth no. SS11 (Silver Sponsor)!
