Preliminary work
1. Prepare base grade exceeding the
planned terrace surface by 50 cm on all
sides with a sloping of 4 % and install
drainage in the ground.
2. Make a stable gravel or ballast bed
(frost-safe) with 2 % sloping, then cover with
fine gravel to level uneven spots.
3. Install concrete edge blocks
(100 × 25 × 5 cm) with a distance of 65 cm
between axes on the entire surface as a
basis for the construction planks on the
gravel bed. On the front side of the const-
ruction planks they are offset back by 5 cm.
Sub-structure
4. Distribute construction planks
(40 × 60 mm) evenly and vertical to the
concrete edge blocks at a distance of 50 cm
between the axes (grooves down). At the
beginning and at the end position two planks
at a distance of 18 cm between the axes.
5. Align planks and level sloping
differences by means of rubber pads.
6. After aligning the construction planks,
screw the substructure in the entire edge
area and the two planks at the beginning
and the end of the terrace and the centre
construction plank together. To do so, drill
through the planks with a 9 mm metal drill
and countersink the holes. Then use the
supplied 6.5 mm concrete drill to drill holes
into the concrete edge blocks and screws
substructure 40/60 for the connection.
7. To prevent the planks from slipping
later on, fasten self-adhesive retaining
band in the centre on the central
construction plank.
Installation of the boards
8. Screw edge clamps to fasten the planks
flush onto the end of the construction
planks. Use a 3 mm metal drill to pre-drill.
Do not tighten the screw, so that the first
board is easily installed.
9. After installing the first boards, push
the house connection profile as end strip
at the building side onto the end of the
plank if necessary.
10. Fix the planks with locking clamps.
To do so, use a 3 mm metal drill to pre-drill
the construction planks. Do not tighten the
screws of the locking clamps.
11. After installation of ca. 3 to 4 rows of
boards, tighten the edge and locking clamps
using a medium torque. Repeat procedure
until the terrace is finally installed.
12. Now cut the boards in the area of the
edge to length and bevel the cutting edge.
13. At the edge of the terrace, fasten
smooth-edged boards on all sides of the
substructure. Screw connection at least
every 50 cm. Place distance pieces across
from the boards between smooth-edged
board and construction plank so that water
drainage is ensured. To do so, drill through
the smooth-edged boards with a 5 mm
metal drill and countersink the holes.
Pre-drill the substructure with a 3 mm metal
drill and then screw on the smooth-edged
boards.
Installation smooth-edged board parallel to
board direction.

Installation smooth-edged board on the
front of board direction.

Installation procedure
Hint:
WAVE barefoot boards (open) require increased
care and cleaning eff orts – it is necessary to
remove dirt from the grooves in the boards
regularly. The distance between the axes of the
construction planks is 40 cm. A minimum sloping
of 2 % in longitudinal direction is absolutely
necessary.

Installation example for substructure of the terrace: The screw connection of the substruc-
ture is made in the entire edge area as well as on the two plank rows at the beginning and the
end of the terrace and on the centre construction plank. This also applies when the plank rows
are constructed from a sequence of several construction planks. The distance between the front
ends of the construction planks should be 1 cm.
