Green concrete solutions for the construction industry 

We help the construction industry achieve climate goals in practice.

Our Geoprime material innovation is a sustainable alternative to cement. It uses industrial side streams to replace cement in concrete elements. 

The resulting concrete elements have material properties that are equivalent to traditional concrete, but up to 75%* lower CO2 emissions from Product stages A1-A3. 

The solution has been developed so that it can be produced in existing concrete plants. The same equipment and process can be used, so manufacturers do not need to make large investments to start producing Geoprime elements. 

Our portfolio currently consists of Geoprime Hollow-Core Slabs, and is expanding into other low-carbon building materials.

Benefits for the construction industry and the designers:

  • Quality products from reliable material manufacturers
  • Solutions that meet industrial standards
  • Transparent, responsible supply chain
  • Meet the environmental criteria as Geoprime adheres to LEED and BREEAM certifications

CASE example  

A significant contributor to CO2 reduction

A Betolar case study shows that the use of Geoprime hollow-core slabs save up to 266 000 kg of CO2 emissions in a typical 7-storey high precast element apartment building.

Hollow-core slabs comprise 32% of the CO2 emissions of a precast residential building, thus the potential to reduce CO2 emissions with low carbon solutions is significant.

Sustainable Hollow-Core Slab technology

Betolar's Geoprime® Hollow Core slab allows construction companies and developers to significantly reduce CO2 emissions.  

Licensed to precast manufacturers, the technology helps to achieve sustainability targets without additional equipment investments or compromises in the technical performance of the product.

It enables  

  • Up to 75%* lower CO2 emissions compared to standard hollow-core slabs
  • Fast mould cycle, curing and retention time for efficient production
  • Similar characteristics with cement-based concrete and compliance with EN standards
