Over the past three decades, the energy sector has been through a significant transition—from a reliance on fossil fuels and nuclear power to the increasing use of renewable energies, like wind and solar power.
With our experience and expertise, DYWIDAG promises to be a reliable partner for the energy sector—providing post-tensioning systems for modern, taller towers and supporting wind tower construction with foundation anchor bolts.
We also support the rehabilitation of hydro-electric dams to meet modern safety standards, providing high-capacity anchoring systems to prevent overturning.
DYWIDAG can assist with wind tower installation—and lifespan management
Since 2012, DYWIDAG has post-tensioned over 2,500 concrete and hybrid towers in Europe, North and South America, Africa, and Asia.
Our installation teams can assist during the design and certification process, optimize installation with our prefabricated Wire-EX tendons—and add sensors for lifespan management.
In addition to wire EX tendons, DYWIDAG windmill bolts will ensure a durable connection between tower foundation and tower or between tower segments. Wind turbine foundations can be stabilized using permanent strand anchors.
Construction, reinforcement, repair and rehabilitation of hydropower structures - with infrastructure monitoring
Our piles and anchors provide uplift resistance for hydroelectric power plants; and our permanent double corrosion-protected tension piles and ground anchors provide uplift resistance for water treatment facilities and hydroelectric structures.
In accordance with new requirements for dam level raising, rehabilitation or seismic upgrade, high capacity permanent strand anchors enable the dam to be strengthened in-situ from the dam crest. In addition to strengthening a dam’s structure, our engineers can configure monitoring systems on anchors to measure changes in anchor forces and structural movement.
Supporting nuclear powerplants during all stages of the life cycle
DYWIDAG supports safe containment at nuclear sites worldwide. Our post-tensioning tendons provide continuous reinforcement for containment structures at nuclear power plants.
Our monitoring systems support monitoring at nuclear sites worldwide. A crucial early warning system for localized areas, with various sensors connected to DYWIDAG`s cloud-based Infrastructure Intelligence can be used to monitor loads or sense impending movements from fault zones at the face of deep excavations for nuclear reactors—without being affected by temperature changes. The sensors enable engineers to remediate high-stress areas with additional soil nails or anchors before excavations continue.
Geotechnical systems protect transmission line towers—safeguarding power supplies
Geotechnical systems, including tension piles, micropiles and ground anchors, stabilize transmission line towers protecting the structure from external forces like severe winds, earthquakes or snow.
DYWIDAG DDCs protect pipelines in seismic areas
The DYWIDAG Ductile Connector (DDC) is a bolted seismic connection system designed to protect framed structures from the impact of seismic activity in earthquake regions around the world. The self-bracing DDC can be used to connect beams-to-columns or columns-to-foundations in framed structures, including high-rise blocks, parkades, and refineries.
The speed at which engineers can construct the precast elements of the DYWIDAG Ductile Connector make it suitable for use in framed structures in earthquake zones around the world.
The DDC’s seismic performance is achieved by using a connector that behaves in a ductile manner—dissipating the energy induced into the system by an earthquake, and reducing the load on all other, less ductile parts of the frame.
Post-tensioning strengthens the circumference of silos and tanks
Our engineers configure internal and external post-tensioning systems to strengthen the circumference of prestressed concrete tanks and silos—so they can withstand the pressure exerted by their contents. Our horizontal and transversal post-tensioning configurations support the construction of a diverse range of tanks and silos—ranging from small digestion tanks to LNG tanks with a capacity of up to 300.000m³.
