Milestone for modern clay construction
For the first time, the German Institute for Building Technology has issued a general type approval for load-bearing clay block masonry using the thin-bed method. The GIMA vertically perforated clay brick may therefore be used for load-bearing walls up to building class 4. In combination with the energy-efficient clay thin-bed mortar from ClayTec, processing is significantly more economical than before.
This is based on the new DIN 18940 standard, which regulates load-bearing clay block masonry comprehensively for the first time. The thin-bed method saves over a third of the working time compared to the thick-bed method and reduces material consumption. In addition to the processing, clay also scores points ecologically. It is not burnt, is fully recyclable and ensures a healthy indoor climate thanks to its moisture-regulating properties.
CO₂-neutral production and circular building system
The production of clay bricks at GIMA is CO₂-neutral. Dried with solar power and waste heat. The wall structure can be completely dismantled. A double-skin construction is recommended for exterior walls: Clay bricks as the load-bearing layer, clay plaster on the inside and a curtain wall on the outside. All materials can be separated by type and recycled.
Formats and possible applications
The GIMA bricks achieve compressive strength class 5 and are available in widths from 115 to 365 mm, adapted to common brick formats. They can be processed using conventional tools and known methods.
Pilot project “GreenConceptLehm“
The first project with the new system has already been realized in Meißen. Building contractors and scientists praise the healthy indoor climate and recyclability. This shows that earth building is ready for widespread use in the modern construction industry.
