Manual and important points of attention for the Staenis grid:
Drainage mortar for terraces

Processing temperature

Only place drainage mortar and screed at temperatures between 10°C and 20°C, this ensures that the surface will not silt up or loosen. Also make sure that the drainage mortar and screed feels fresh/cold when placed or that the ambient temperature does not fall below 5°C.

Placement Methods

There are 2 different placement methods for installing the grid in your space.

Approved floor covering

expansion joints


*Fix the grids by placing weight in or on a compartment Click a row of slats from the grid to be able to pass with a barrow. Due to the fixation of the grid, the distance will remain the same after the row of slats click apart.

Placement of the Staenis grid

Height adjustment

You can achieve the best possible flatness with a laser that corresponds to a line on a wooden tool / lath or folding rule. If you use a digital receiver, the screed will in any case cause differences in height of a few mm. A digital spirit level is also not recommended. Try to use a digital receiver or spirit level only to set out a number of points, in order to adjust everything in between by means of a vertical adjustment, tensioned rope or aluminium rule.


We ask you to pay close attention to the height adjustment during installation and to regularly check the flatness using a long aluminium rule or laser.

Installing drainage mortar

* Only manually press / polish the drainage mortar and screed with a screeding iron and compact with a large sanding board. Do not press with your feet, this can cause height differences.
