next generation of pre-fab production lines and concrete SANDWICH

In 2013 G.tecz Engineering developed the HYBRID WALL ELEMENT, a sandwich of UHPC layers and a light weight foam concrete in-between. With it comes a fast and effective wet in wet production line for the realization of huge volumes. The line is modular and also mobile - thus made for easy and simple productions all over the world.

Hybrid Wall

The hybrid concrete wall is a sandwich of High Performance or Ultra High Performance concrete layers and a core made of infra light weight concrete with insulation properties - produced in an endless extortion process and it's monolithic.

  • Hybrid concrete wall element
  • Fairface concrete
  • Insulation properties
  • Colors possible
  • thickness up to 40cm
  • Tailored sizes possible
  • Load bearing elements
  • Category: Masonry
  • 90% Local raw-materials used
  • 100% recycling possible
  • No traditional concrete pre-fab element!
  • No primary construction (steel, concrete, ...) required.

Production Line

G.tecz developed an unique machine that extrudes the hybrid wall panels in one process - endless. The compact and robust machine is modular and can be setup very fast in any region of this world.

  • Compact and robust machine
  • High production speed
  • Plug-and-Produce technology
  • Modular, fast installation
  • Low energy consumption
  • Less production space required

The IDeA

Hybrid wall panels are developed for the production and building of low-cost and affordable houses. The easy to use production line and the fast hardening concrete will allow a fast usage of the wall elements. Our wall system enables you the build houses with your team in a very short time and thus have a faster growth of your business. Up to 10times faster compared with traditional masonry constructions or other pre-fab systems.


  • Walls, 5cm to 25cm load bearing wall elements.
  • Thermal insulation walls > 25cm (in 2019)
  • Partition walls, not load bearing.
  • Masonry elements
  • Facade elements

Low cost houses

The low-cost houses can be realized with 10cm thick hybrid wall elements and up to two stories high. With our wall panels included, good houses can be realized from 12.000 Euros. *)

Affordable houses

Affordable houses or Tiny houses can be realized with a wall thickness of 25cm and up to two stories high. With the wall elements, houses can be realized from 25.000 Euros. *)

Energy Saving houses

This category of houses can be realized with 40cm thick wall elements. Those will fulfill the regulations of the EnEv and can be realized from 100.000 Euros. *)
