Information that must be indicated
in an order:
3.2. Place of use either indoors
or outside, whether the established pavement
is only to be walked on or is it also
intended for cars to drive on.
3.3. We recommend obtaining 1015%
more material to compensate for the installation
Possible places of usage:
4.1. For covering garden paths and sites
4.2. For covering garage driveways (UM
3/5 and UM 7/5)
4.3. In garden design
4.4. For finishing fireplaces and walls

5.1. We recommend ordering installation
works from Ungru Paekivi OÜ, who
will give a 2-year warranty to both the
material and the installation.
5.2. When performing installation works
yourself, we advise using lime mortar,
which is made of clean (washed) sand and
clean water. We do not recommend using
Portland cement, which may cause the stones
to change their colour.
5.3. Ready-made mortars or mixtures of
adhesive intended for the installation
of natural stones may also be used when
installing limestone plates.
5.4. Attention should be paid on making
a proper hydroinsulation.
5.5. When making garden paths, we advise
installing the stone plates on a pre-tightened
base made of crushed stone and sand. Fill
the joints with small crushed stones,
stone chips or granite siftings. Grass
joints are also an option.
