This spacer is not designed to be used in concrete structures. It is
used to maintain distance of stones and
tiles from the floor surface,
14mm height and 3.5mm. Between tiles, the purpose of using this part is
to create a special stone or
tile floor in order to prevent accumulation
of water and rain on its surface and guide the water 14 mm beneath the
surface...These pieces may also be used on the roof tops to prevent
damage to the sealed surface. Meanwhile this is also used to prevent
water accumulation in pedestrian crossing areas. Instruction for use:
These base plates are placed under stones and tiles with corners of
tiles to
meet in the center of the spacer leaving 3.5 mm. distances from
each other.
