Elematic S.A (Pty) Ltd

Hollow-core concrete slab manufacturer

Newly established hollow-core concrete slab manufacturer, Elematic South Africa (ESA) began full production in February last year. They are already looking at expanding due to a booming construction market.

Elematic SA manufactures precast concrete hollow core slabs for the South African market.  It satisfies the high demand for high quality, reliable products that are available within short lead times in an industry where building products are almost insatiable and completion times are short. 

Elematic is a well established international brand. The company was established in Finland in 1959, and has since set up precast production plants in more than 70 countries worldwide.  As part of the Consolis Group, which focuses on research and development in cement and precast concrete products, Elematic is backed by extensive knowledge and experience.

Elematic supplies the latest available technology in precast products and are able to contribute to alleviating the pressure that the skills shortage is placing on the construction sector, and help speed up the delivery of infrastructure in the country.  Elematic provides itself on setting new benchmarks in quality in the industry. Elematic’s technology produces slabs of excellent quality – this is truly a world class product. 

Why precast concrete?

A precast slab can be constructed much faster than a cast-in-situ slab as it does not require curing time and the need for back-propping is eliminated. The slabs are also comparatively light, making them easy to handle and reducing the load imposed on a building’s foundations.  Extensive research has been done and the high level of support as well as the sophisticated technology that Elematic offers is of excellent standard.  Elematic in Finland provides turnkey solutions for setting up production plants, and will equip the new facility for Elematic SA with state-of-the art machinery and technology.  Elematic concentrates its energy on providing hollow core slabs of an internationally high standard and within a competitive lead time.  Elematic’s technology allows for the production of a wide range of precast concrete products, and the factory has been designed to accommodate the manufacture of other precast products in future.  Elematic slabs are one of the most advanced products in the precast concrete industry. 

Advantages of hollow care slabs:

• Can be used in a wide range of applications such as floors, roofs and walls.
• A highly automated production process.
• Smooth even bottom surfaces mean false ceilings can be omitted.
• Good sound insulation properties.
• Because of the longitudinal cores, weight of the floor is reduced.
• The voids in hollow core can be used for technical installations, i.e.  ventilation conduits, plumbing and electrical pipes etc.
• Short construction time, absence of scaffolding, high mechanical and durability performance, excellent span-depth ratio and good flexibility in design.
• Hollow core can be designed to meet different fire class requirements.
• Hollow core can be used with all types of supporting structures i.e. bearing walls, skeletal concrete structures or steel frames.
• The reduced weight of slabs gives savings in foundations and structures.
• Longer spans, less support, more freedom in floor plan design.
• Dry erection - only the joints need to be concreted.
