Porotherm Profi Dryfix Extra - a groundbreaking technique for building

Porotherm Profi Dryfix Extra System

Тhe last two decades were marked with great innovation in the field of construction. The brick as a basic building element undergoes serious changes and turns into a clay block with a tongue and groove connection. Clay blocks can be put down quickly and effortlessly. This saves time for builders and craftsmen.

However, the new era in the construction comes namely with the Porotherm Profi Dryfix Extra system. Wienerberger introduces a groundbreaking technique for building interior walls with Porotherm glue bricks. Just like when gluing with adhesive mortar, these flat-ground quick building blocks are also glued horizontally to each other. The vertical joints are realized by means of a tongue and groove connection. The difference with glue mortar? Porotherm Dryfix is ​​not cement-bound. It is a PU adhesive in aerosols that is applied with a universal spray gun.  The new system provides plenty of advantages that are going to change our ideas about how to build masonry walls.
