Chaglla Dam is a hydroelectric dam set up on the Huallaga River, in the Huánuco region of Peru. The dam is 203m heigh with an installed maximum capacity of 456 MW.

For this major dam project, Dextra continuously delivered to Brazilian contractors Odebrecht its Rolltec rebar coupler solution between 2012 and 2015.

Rolltec is the most popular rebar slicing solution in Latin America, providing a competitive alternative to lap splices.

The rebar preparation is supported by a unique light equipment, operated by a single operator. The Rolltec machine is relatively easy to transport and convenient to install even on most remote locations such as dam construction sites.

More than just couplers and equipment, Dextra also took in charge the machine commissioning and operator training, making sure the contractor team make the most out of their rebar coupler solution.

The Bahr El Baqar wastewater treatment plant is located in the northern governorate of Port Said, with a daily output capacity of 5.6 million cubic meters. It is a joint venture between the Arab Contractors Company and Orascom Construction.

The plant is the world’s largest of its kind, holding three Guinness World Records: the world’s largest water treatment facility, processing 64.8 cbm of water per second, largest sludge treatment plant, and largest single-operator ozone generating plant.

Dextra is proud to be a part of this project, supplying Rolltec rebar couplers for the reinforcement of the plant’s concrete structures.

Rolltec is a CARES approved rolled parallel threaded mechanical splicing system designed for the connection of concrete reinforcing bars from Ø12 to 50 mm (ASTM #4 to #18). It offers fast and easy preparation and installation at site.

For this remote construction sites, a Bartec rebar preparation equipment set was delivered to site in its container. A total of 120,000 rebar couplers were used on the project over a two-years period.

Jizan Flood Mitigation Channel is an under-construction infrastructure project in Jizan Economic City, Saudi Arabia.

Being located on the coastline, the city faces the risk of floods due to the frequent torrential rainfalls.

The flood channel plays the important role of protecting these downstream areas from major flood damage.

The channel will be exposed to seawater and water environmental contaminants that can influence the corrosion of steel: for this reason, Dextra ASTEC glass fiber reinforced polymer (GFRP) rebar was the perfect solution for the project. Almost 2 million meters of the GFRP rebar were delivered.

ASTEC GFRP rebar is a corrosive-free non-metallic reinforcing bar that provides higher tensile strength than steel while being lighter in weight.

Upon its completion, the project will be the world’s largest construction using GFRP rebars as its concrete reinforcement.

Santo Antônio Dam is a hydroelectric dam set up on the Mareira River, in the state of Rondônia, Brazil. The dam is powered by 50 turbines for a total capacity of 3,580 MW.

For this major dam project, Dextra Do Brasil delivered to contractors Odebrecht & Andrade Gutierrezits its Rolltec rebar coupler solution.

Rolltec is the most popular rebar slicing solution in Brazil, providing a competitive alternative to lap splices. The rebar preparation is supported by a unique light equipment, operated by a single operator. The Rolltec machine is relatively easy to transport and convenient to install even on most remote locations such as dam construction sites.

On the Santo Antonio dam, rebar coupler were used to reconnect bent rebar. To do so, a straight bar is previously threaded (A/B/C thread length). The bar is then bent according to project requirements.

If needed, to protect the thread coupler can be temporarily set up onto the rebar as well.

Please consult us for more technical information about coupler applications on bent bars.

The Bakheng Water Treatment Plant is located in the Bakheng district of Phnom Penh, Cambodia. The plant will be built to improve the water supply in this area and eventually give a 60 percent increase in drinking water delivery capacity due to substantial urban expansion.

A drinking water treatment plant and transfer pipelines are part of the project. The supply system will eventually provide drinking water to more than 1.5 million residents in Phnom Penh’s north-east.

By the end of Phase 1, the plant should be operational to provide drinking water to the more than 750,000 inhabitants of the area. By the end of Phase 2, its capacity will be doubled.

The project includes earthworks and soil treatment, civil engineering design of the structures, equipment installation, power supply to the equipment, and system automation.

Dextra supplied Glass Fiber Reinforced Polymer (GFRP) rebars which were installed in bored piles instead of reinforcement of traditional steel rebars to facilitate the TMB breakthrough in the underground waterway tunnel.

Reventazón Dam is a concrete-face rock-fill dam set up on the Reventazón River, in the Limon province of Costa Rica. The dam, inaugurated end of 2016, is the largest power station in the country with a total power capacity of 305MW. The project has become a model in term of environmental integration, featuring passages for animals.

For this major dam project, Dextra Latin America continuously delivered and supported contractor ICE from 2010 to 2016. Dextra supplied its Rolltec rebar splicing solution, couplers and machine. Rolltec is the most popular rebar slicing solution in Latin America, providing a competitive alternative to lap splices.

The rebar preparation is supported by a unique light equipment, operated by a single operator. The Rolltec machine is relatively easy to transport and convenient to install even on most remote locations such as dam construction sites.

Rolltec splices were used inside the water tunnels, installed on bent rebar. For that kind of application, the straight bar has to be threaded, then bended. During the bending operation, a coupler may be temporarily fit onto the bar end in order to protect the thread.Rolltec splices were used inside the water tunnels, installed on bent rebar.

Dextra Rolltec couplers were also installed into the tall structure (130m high) as a way to splice rebar vertically.
