1. Establish a ballast bed (including drainage) that is circumferentially larger than the terrace by 50 cm with a 4 % gradient

2. Create a ballast bed using crushed stone with a 2 % gradient.



3. In all ConStep mounting plates, click all single and double mounts at the same height and centrally adhere into place using a piece of retaining band.

4. Position a ConStep panel with a double mount at a distance of 8 cm to the house wall and with a maximum 50 cm centre distance to the next ConStep panel with double mount.

5. Position the ConStep panel with single mount at a maximum 40 cm centre distance to the next row.

6. Conclude the end of the terrace with a ConStep double mount. Click the sub-construction into place.

7. Minimise protrusions. In order to do so, rotate the ConStep panel where necessary.

8. In the event of terrace sizes with a construction beam length > 3 m: Saw the ConStep connecting strip to a length of 25 cm, screw on one side and, in doing so, observe the beam expansion gap of 1 cm.

9. In the event of terrace sizes with a deckboard length > 3 m: The later assembly of the connection profile to the side butt joint of the ConStep double mount must be positioned as illustrated.

10. Check the distances of the entire sub-construction, compensate for unevenness and gradient inaccuracies using crushed stone.


11. In a crosswise manner, reinforce the entire sub-construction with perforated tape via the ConStep assembly clip.

12. When laying the deckboard, equip the top of the central construction beam with retaining band to prevent slipping.


13. At a distance of 12 mm from the edge, saw a 5 mm deep and 2 mm wide cut into the construction beams on the side on which the deckboards shall be laid. Position the edge clamp into this groove and, using pliers, fasten together with the construction beam and push the deckboard into the edge clamp.


14. Position the joined locking clamp on to the construction beam, push against the deckboard and lock using pliers. Using the supplied screw, lock the locking clamp on to the construction beam in every third row of deckboards.

15. After the penultimate deckboard, determine the required width for the last deckboard and saw the construction beams flush. In doing so, note that the deckboard protrusion should measure 1.5 cm.


16. On the frontal side, pre-drill the connection profile in the direction of the construction beam and screw into place. Proceed as illustrated in Step 9 when dealing with butt joints.

17. Assemble the connection profile parallel to the construction beam using a fastening screw. The screw connection must be located no further than 6 cm from the ends of the deckboards and at intervals no greater than 50 cm. The connection profile butt joint assumes the sub-construction connection profile.
