Why Elematic SA's Precast Concrete Products
Precast concrete technology is known worldwide as a safe, efficient and cost-effective way to build. Its advantages are numerous. The fact that our products are manufactured off-site under strictly controlled conditions ensures high quality and reliable products.
Precast concrete floor slabs, walls, stairs, or other components can be transported to site and installed as needed, keeping site logistics to a minimum. Construction times are fast – time saved usually translates into cost savings and higher project profitability. The life cycle and maintenance costs of precast concrete products are lower than those of comparable cast-in-situ solutions. The factory production process is designed to be efficient, using fewer materials and labour and producing less waste, giving it a lower CO2 footprint.
Precast concrete products work particularly well for modular construction and can be used in a wide range of applications. The use of prestressed hollow core concrete slabs has several benefits:
Guaranteeing
Efficiency
More efficient than cast-in-situ construction as it eliminates the need for back-propping and allows other trades access beneath the slabs immediately, significantly speeding up construction times.
High Quality Standards
Products are manufactured off-site in a controlled environment and to strict quality standards, providing a far greater guarantee of accuracy and performance.
Excellent Customer Service
Elematic SA is committed to delivering exceptional customer service through responsive support, expert guidance, and a proactive approach that ensures projects run smoothly from planning to completion.
Custom Solutions
Elematic SA’s professional designers and engineers are able to work closely with other project professionals to design and deliver the optimum solution at an affordable cost. Clients are assured of a solution tailored to their specific needs rather than a one-size-fits-all approach.
Cost Savings
Time savings almost always result in cost savings for the client.
Precast Concrete FAQs
Precast concrete is a construction material that is cast and cured in a controlled factory environment before being transported to a construction site. This method ensures superior quality and precision compared to concrete poured on-site. Used in a wide range of applications, from floors and walls to beams and staircases, precast concrete is valued for its durability, strength, and versatility.
At Elematic SA, our precast solutions are custom-designed to meet the specific requirements of each project using state-of-the-art techniques and material, which make it better for the environment. Our products offer efficient, cost-effective, and sustainable construction options.
Precast concrete is made in a factory setting using a controlled process designed to ensure precision, quality, and sustainability. It begins with designing and creating custom moulds tailored to the project’s needs. High-quality concrete, now incorporating Elematic SA’s cutting-edge cement replacement, is mixed and poured into these moulds. This innovative material, introduced in 2024, has reduced our cement usage by nearly 30%, significantly lowering CO₂ emissions without compromising the strength, durability, or performance of our products. The concrete is then compacted and cured under regulated conditions to maximize its quality.
Our streamlined manufacturing processes also enable shorter lead times, ensuring projects stay on schedule while benefiting from the sustainable advantages of our concrete. Once cured, the precast components are thoroughly inspected, transported to the site, and assembled with precision. At Elematic SA, we combine efficiency and sustainability to deliver high-performance solutions for modern construction needs. Contact us to find out more.

Precast concrete is known for its exceptional durability and longevity, often lasting several decades or even centuries with proper maintenance. The lifespan of precast concrete can vary depending on factors such as environmental conditions, exposure to harsh weather, and the specific application. Generally, well-maintained precast concrete can last 50 to 100 years or more, making it an excellent long-term investment for construction projects.
Yes, you can drill into precast concrete. However, it requires the right tools, techniques, and planning to ensure the structural integrity of the concrete is maintained. Precast concrete is a strong, dense material, so using specialised equipment such as a hammer drill or a diamond-tipped bit is essential for creating clean, precise holes. It is imperative that drilling into areas with embedded reinforcement, such as steel rebar, is avoided as this could weaken the structural element.
At Elematic SA, our precast components are designed with flexibility in mind, and we can provide guidance on safe drilling practices or pre-install fixings during the manufacturing process to suit your project requirements. Additionally, by incorporating sustainable practices, such as reducing cement usage by nearly 30% in our products, we ensure our concrete is not only durable but also environmentally responsible. For any modifications, we recommend consulting our team to ensure the best results.
