Curetec: Outperforming Competitors in Tunnel Segment and Sleeper Curing

We are building tunnel segments efficiently, sustainably, and with precision for strength and durability, avers André Dienst, Managing Director.

As global tunneling and railway infrastructure sectors expand, the demand for durable, high-quality tunnel segments and railway sleepers is driving the need for advanced concrete curing. Curetec, the supplier of choice for world’s leading producers, delivers unmatched efficiency and sustainability through its cutting-edge curing systems.

Renowned for replacing all curing systems at Asia’s largest tunnel segment production facility, owned by Shanghai Tunnel Construction, Curetec proved its CureSteam system, powered by the Low-Pressure Vapor Generator (NDG), is the most energy-efficient and high-performing solution globally. Today, Curetec equips all major tunnel segment and sleeper producers worldwide, offering innovative technology and a comprehensive control system with full online access, detailed energy consumption data, and complete curing records to ensure perfect curing regimes, maximizing element durability for critical infrastructure projects.

Breakthrough with Shanghai Tunnel Construction

Curetec’s dominance was cemented through its partnership with Shanghai Tunnel Construction, Asia’s largest tunnel segment producer. After rigorous testing, the CureSteam system outperformed competitors, achieving 50% plus energy savings over traditional steam boilers while maintaining precise temperature control (±2°C). This led to Curetec replacing all curing systems at Shanghai’s facility, setting a global benchmark for efficiency and sustainability. The NDG’s tailored energy output (up to 2400 kWh) and integrated ventilation/humidification ensure optimal curing, even in Shanghai’s humid subtropical climate.

Powering Sleeper Curing for Growing Infrastructure

Curetec’s expertise extends to railway sleeper curing, vital for booming infrastructure in western China, India, and Africa. In western China, Curetec supports facilities like Shudao Investment Group’s Nanchong plant, China Railway’s Hong ‘an plant and more, producing sleepers for high-speed and heavy duty rail. In India (eg, Dedicated Freight Corridor) and Africa (eg. Standard Gauge Railway), Curetec’s CureSteam system will deliver energy-efficient curing for pre-stressed sleepers, meeting stringent standards (e.g., EN 13230). Its precise yet flexible control system ensures durability, reducing maintenance in harsh climates.

Versatile Solutions for Modern Production Facilities

Curetec’s technology adapts seamlessly to modern carousel plants, line factories, and project site production facilities, thanks to the mobility of all systems. Whether for automated plants in western China or temporary setups in Africa, Curetec’s solutions ensure consistent quality. The CureTent system is the perfect addition for project sites or temporary facilities, enabling controlled curing under challenging conditions. These mobile, easy-to-install tents maintain precise temperature and humidity, ideal for on-site production of tunnel segments, sleepers, or other precast elements, ensuring durability without compromising efficiency.

Global Leadership in Curing Solutions

Curetec supplies all major tunnel segment and sleeper producers, from Europe to Asia-Pacific and Africa, supporting projects like metro tunnels and high-speed railways. The CureSteam system excels in:

• Precision: Controlled curing ensures compliance with global standards.
• Energy Efficiency: NDG cuts energy use by 50% plus, critical in markets like Europe and India’s growing grid.
• Advanced Controls: Full online access provides real-time curing data, energy metrics, and records, enabling producers to demonstrate quality to clients.

Enhancing Durability and Sustainability

Curetec’s integrated control platform logs curing parameters, ensuring maximum strength for tunnel segments and sleepers. This transparency helps producers worldwide showcase compliance, boosting credibility for employers and authorities. In warming climates, Curetec’s systems adapt, minimizing summer cooling energy while leveraging milder winters.

Why Curetec Leads

Curetec’s Shanghai production center ensures rapid delivery across Asia-Pacific and beyond, supporting fast-paced projects in India and Africa. Continuous R&D drives innovations, reducing emissions and waste, aligning with sustainability goals. Unlike traditional methods, Curetec’s mobile systems transform production by balancing productivity, quality, and environmental responsibility.

Building Resilient Infrastructure

Curetec’s leadership in tunnel segment and sleeper curing empowers the global tunneling and railway sectors to build resilient infrastructure. From Shanghai’s mega-facility to western China’s rail hubs, India’s freight corridors, Africa’s emerging networks, and mobile project sites, Curetec’s CureSteam and CureTent systems set the standard for efficiency and durability. For producers optimizing energy and ensuring superior outcomes, Curetec is the trusted partner driving the future of infrastructure.
