We know that time is critical in any construction project. That’s why our production and logistics are organized to ensure fast delivery, without compromising on quality.
To give you an idea of what to expect:
The design phase typically takes around 10–12 weeks. This is followed by a pre-production phase, including formwork fabrication, which usually takes 4–6 weeks before actual production begins. Our production capacity allows us to cast between one and several elements per day, depending on the project’s scale, the size of the elements, and the number of available molds. As a standard, we typically cast one element per day, four days a week.
We work hard to ensure our clients receive their UHPC elements on time, so construction projects can proceed smoothly and according to schedule. Our goal is to provide you with the confidence that comes from knowing we understand how critical efficient delivery is in the construction industry.
It’s worth noting that delivery time may naturally vary depending on the project scope and the design and complexity of the elements.

Frequently Asked Questions
How Does UHPC Compare to Traditional Concrete in Terms of Cost?
When conducting a cost analysis, UHPC generally costs significantly more than traditional concrete. However, its efficiency and durability can help balance out the initial investment, resulting in long-term savings on maintenance and overall project expenses. For instance, while a traditional concrete structure may require frequent repairs, a UHPC structure could last much longer without the need for extensive upkeep. This can be particularly advantageous for large projects or structures exposed to harsh conditions.
What Are the Limitations of Using UHPC in Construction?
Although UHPC boasts remarkable strength, it presents durability and workability challenges. Focusing solely on its strength can result in brittleness. It’s crucial to find a balance between performance features for successful application in construction projects. For instance, while a UHPC beam can support heavy loads, if it lacks flexibility, it may crack under stress.
Can UHPC Be Recycled After Its Lifespan?
Yes, UHPC can be recycled after its lifespan. Using specialised processes helps promote sustainable building practices, reduce waste, and conserve resources. However, it’s important to adjust the mix design and prepare aggregates properly for effective reuse. For example, crushed UHPC can be used as aggregate in new concrete, contributing to a circular economy in construction.
What Certifications or Standards Apply to UHPC Materials?
When building a bridge with Ultra-High Performance Concrete (UHPC), it’s essential to obtain ASTM C certifications. These certifications ensure that the materials meet established performance standards and specifications. By adhering to these standards, you can ensure the strength and durability of your infrastructure projects, providing safe and reliable structures for the community.
How Does Temperature Affect the Curing Process of UHPC?
Temperature has a significant impact on the curing process of UHPC (Ultra-High Performance Concrete). To achieve optimal strength and durability, it’s essential to use effective curing methods and maintain precise temperature control. This ensures the microstructure develops correctly and reduces the risk of issues during hydration. For instance, higher temperatures can accelerate the curing process but may lead to cracking if not managed properly. Conversely, low temperatures can slow down hydration, delaying strength gain. Understanding and managing these temperature effects is crucial for successful UHPC applications.
