Modular system walls - Alcasystem A revolution in bathroom construction

Alcasystem can replace both brick and plasterboard walls. It can be used both in larger development projects and in the construction of family houses or during renovations. Prefabricated walls brought to the construction site significantly speed up the work and thus save time and costs. The bigger the project, the bigger the savings.

Advantages of Alcasystem modular walls

Prefabrication and speed

course info icon

The entire wall is created in a production plant outside the construction site - it is brought to the construction site and installed only after the overall completion.

Thanks to this, the installation is up to 6 times faster - it usually takes up to 2 hours on the construction site.

The whole solution of modular construction minimizes the impact on the environment.

Not only the speed of construction contributes to the reduction of the ecological footprint, but also the minimization of waste, which is generated during classic bathroom construction.

Certification and exams

Thanks to our wide product portfolio, we supply all components of prefabricated walls. We can therefore offer a guarantee of up to 15 years for the entire solution.

Modular system walls - Alcasystem Basic elements of the system

The entire wall is made up of three basic elements (profiles, connectors, anchors), thanks to which its parameters can be changed very easily. In this way, we can easily adapt to any space where Alcasystem is needed.

Separate WC modules, mounting frames, pipe distributions and other optional accessories are part of the Alcasystem wall - individually according to each project.

Compact solution for every construction

The advantage of the Alcasystem modular system is its versatility.
