Lay concrete edge stones (100 x 25 x 5 cm) at a centre distance of 75 cm on the gravel bed with gradient, turn the frontal side inwards by 10 cm in the direction of the construction beams.
Evenly distribute the construction beams (90 x 90 mm) transversely to the concrete edge stones (groove at the bottom), pay attention to a 10 cm protrusion.
Arrange two beams respectively at the start and the end. Lay 10 mm rubber pads beneath the construction beams, compensate for possible gradient differences using further rubber pads.
In the event of a terrace width greater than 360 cm, always arrange the construction beam joints in an offset manner (distance of 1 cm).
Align the construction beams, screw the sub-construction in the edge area as well as both start and end beams to the middle beam. Cut the construction beams to size, ensuring they are flush, 10 cm protrusion.
The 12 cm long construction beams measuring 60 x 40 cm are placed upright and then fastened to the ends of the construction beams on the left and right hand sides.
Adhere the retaining band to the construction beam located centrally beneath the floorboards.
Screw the edge clip flush to the end of the construction beams in order to fix the floorboard into place.
Following assembly of the first floorboards, push the house connection profile as a border strip to the house facade to the end of the floorboard (optional). Fix the floorboards with a clip. Tighten the screw in such a manner that the clip is parallel to the sub-construction.
Loosely insert the groove strip into the floorboard groove, apply the next floorboard, push on to the groove strip, fix the floorboard using the clip.
Repeat the process until the terrace is fully laid.
Cut the floorboards to size in the edge area facing the construction beams, chamfer the cutting edge. See Figures 9a and 9b.
The frontal side of the smooth edge boards must be 1.2 cm shorter than the construction beams at the end of the terrace - pay attention to distances!
Circumferentially fasten smooth edge boards to the sub-construction. On the frontal side, screw the smooth edge board to the sub-construction beams.
Screw every 50 cm in a parallel manner along the construction beams, apply spacer screws between the smooth edge board and the construction beam.
