Montage terrace tiles on mortar bags with concrete should take place in a place where four slabs meet. To keep the space between tiles equal, use a spacer cross. This gap is needed just like a terrace with adjustable or fixed supports. It allows you to drain water.
Unfortunately, so far nobody has patented a good way to arrange such a terrace in one area.
Correcting them with a rubber mallet is unfortunately not very precise and exposes the boards to the risk of latent cracks, which will become visible under the influence of moisture over time.
The surface, which has been laid on the bags with concrete, cannot be walked on for several days.
While the terrace made on adjustable pedestals can be used from day one. The advantage of both methods is that they can be easily and quickly disassembled when damaged tiles need to be replaced.
the quality of the installation and force uneven joints and differences in height between the tiles laid on the terrace. Will adversely affect the quality in the use of the terrace thus made.
Getting the correct assembly and aesthetics of the whole assumption is very difficult and requires many years of experience in assembly using this technique.
In the event of entering a newly mounted terrace or too strong one hammer impact on the tiles may bend and permanently remain in the wrong position of the bag with solidifying cement and leave permanent inaccuracy of assembly in terms of the width of the joints or the level of the tiles relative to each other.
The use of terrace adjustable pedestals excludes demolition from the top. Such a system allows disassembly of one tiles and gives the possibility of adjusting a specific adjustable pedestals.
Such possibilities are further increased if we use a adjustable pedestals with a self-leveling head. Then the tiles are subject to the collision-free adjustment of the terrace plane.
