The precast concrete sector is experiencing dynamic growth, fuelled by increasing demands for sustainability, production efficiency, and material innovation. In this interview, José Maria Vaquero — Corporate Product Line Manager for Precast Concrete at Mapei Group — shares how Mapei is actively supporting manufacturers with tailored technical expertise and high-performance solutions. From advanced admixtures for concrete made with low-clinker cements to technologies that reduce waste and carbon emissions, Mapei offers a holistic approach that enhances durability, optimizes production processes, and fosters circularity.

The second phase of the Modular Prefab Construction project incorporates Mapefibre ST 40 Plus macro-synthetic fibres into precast modular slabs made of concrete-and-timber to reinforce the concrete, while also enhancing its mechanical performance, sustainability and modularity. Using Mapefibre ST 40 Plus reduces the need for conventional reinforcement, promotes a circular economy and simplifies the precast production process. Presented at the FIB 2025 symposium, the project provides an innovative solution for the future of construction.

From Finland’s new low-emission building regulations to the Mapei solutions to produce low-carbon concrete: Mapei OY stands out for its innovative admixtures from the RE-CON line and CUBE System. In this article, Mika Liikonen and Jukka Tuohino share how the company’s commitment to sustainability is reshaping the Finnish market and driving a concrete shift toward low-carbon construction.
