Fixings for brickwork

GHAS® system

Steel for Bricks

GHAS® system

A construction system consisting of enclosures whose thickness completely crosses in front of the structure, with a horizontal mortar joint being the only indispensable requirement.

As with conventional enclosures, they have to be designed to withstand vertical and horizontal forces.


  • Improves the performance of face brick façades.
  • Practically and cheaply eliminates construction problems inherent to the conventional building system of these façades.
  • Avoids fissures and cracks.
  • Product with SAO device.
  • CTE compliant (stability and fissures)
  • Covered by DAU 12/076.
  • Enhanced aesthetics: floor structure edges are not visible.
  • Water tightness of the brickwork.
  • No thermal bridges on the floor structure face.
  • Possibility of ventilated façade.
  • Quick installation.
  • Cheap system.
  • Does not require specialist personnel.

  • Brick façades.
  • Brickwork made with concrete or cinder blocks.
  • Inner partition walls.

Construction system consisting of the following products:

  • GEOANC®: Strongest fixing system on the market. The fault occurs in the joint between the mortar and the brick.
  • Includes Operator-Monitored System (SAO)
  • GEOFOR®: Reinforcement with auto-overlap and SAO devices.
  • GEOPOST®: Telescopic posts with devices.

Two types of façades can be made:

  • Self-supporting
  • Ventilated

The only difference between one and the other is the inclusion of a continuous ventilation cavity.
