Simple assembly

  • Avoid contact between the construction elements.
  • Ensure that the subsoil is firm and has a good load bearing capacity. For applications that require an official technical approval, a static sufficiently measured, bearing and walkable foundation as a support for torroTIMBER® boards /sub-constructions is also required.
  • Holes should be pre-drilled so that the part to be fixed is 2 mm larger and the retaining drill hole is 1 mm smaller (0.5 mm in the case of metric screws) than the screw diameter.
  • Observe the minimum clearances of the expansion joints so that the construction can expand without force if necessary and a sufficient amount of ventilation from underneath is ensured.
  • Cutting the longitudinal side of the boards may result in board offset.
  • Do not lash down or brace the deck during construction.
  • Distance between the deck board and all fixed components: 20 mm
  • Do not fill cavity spaces between the level surface of the gravel and sub-construction elements.
  • Recommended minimum gradient of 2 % in the longitudinal direction of the boards.
  • Maximum deck board protrusion over the last sub-construction is 50 mm.
  • Production-related dimension tolerances regarding length, width and thickness are to be taken into account during assembly and the dimensions on the construction must be examined once again.
  • The planks are to be cut off at right angles and then to chamfer.

Simple assembly for all structure types

Setup could not be any easier

We want you to enjoy your terrace for a long time. Only use original torroTIMBER® parts and observe our processing recommendations to ensure that our warranty does not become void.

Coordination with the manufacturer must take place and respective approval must be obtained in the event of special structures that deviate from these processing recommendations or the online planner in order for any potential warranty claims to be accepted.

Simply pay attention to the laying direction

Lay all of the boards in the same direction in order to obtain a homogeneous surface effect. This direction is shown by an arrow in the board groove or on a label on the board. Mix the boards prior to laying. This allows the slight differences in the colour of the boards to emphasise the natural appearance.

Assembly on concrete edge stones

In accordance with constructive wood preservation principles, we recommend to lay the boards with a minimum gradient of 2% in the longitudinal direction. As a result, the water can flow away, waterlogging and building damage is prevented and water stains are minimised.

Preparation of the subsurface

1. Establish a soil formation
 Establish a soil formation with a gradient of 4%.
2. Create a ballast bed
Whilst ensuring that it protrudes by 500 mm around the circumference of the deck, create a ballast bed (including drainage) with a 2% gradient. Apply fine grit to the ballast bed with a 2% gradient.

Assembly of the subconstruction

3. Lay the concrete edge stones
Lay the concrete edge stones (100 x 25 x 5 cm) on a gradient gravel bed with a centre distance of 500 mm.
4. Distribute the construction beams
Equally distribute the construction beams (40 x 40 mm) transverse to the concrete edge stones (the groove is at the bottom), ensuring that there is a protrusion of 50 mm on the end face (see Detail 8). Screw the construction beams at the beginning, the centre and the end of the board and the lateral supporting points for the construction beams to the concrete slabs. Place two beams each at the beginning and the end (axial dimension: 160 mm). Place 10 mm rubber pads under the construction beam and balance out any gradient-related differences using additional rubber pads.
5. Offset positioning
The joints of the construction beams should always be positioned offset from each other should the width of the deck exceed 3 m.
6. Cut the connecting clamp
Cut the connecting clamp to 250 mm so that the beam joints are joined to each other and then screw tightly on one side (clearance of the joints: 10 mm). Connecting clamps make it possible to create decks that are larger than 12 x 12 m without a requirement for structural expansion joints.
7. Saw the connection clamp
Saw a width of 20 mm and a depth of 10 mm out of the connecting clamp in the area of the screwed connection so that the connection profile can be mounted later.
8. Additional piece of construction beam
Mount an additional piece of construction beam in the area of the butt joints of the smooth edge boards should the deck boards be longer than 3 m.
9. Adhere retaining band
Adhere retaining band to the centre construction beam.

Assembly of the boards with clip

10. Place an edge clip
Place an edge clip at the beginning of the face of the construction beam so that it is flush with the beam, pre-drill to a depth of 3 mm and loosely fix in place using a screw (do not tighten yet).
11. Push the first board
Push the first board onto the positioned edge clip. Use the clip for the following boards, pre-drill to a depth of 3 mm and loosely fix it to the construction beam using the enclosed screws. Now press the next board against it until the clip is positioned horizontally. Tighten the clip applying an average torque after approx. 5 boards have been laid. Repeat up to the penultimate board.
12. Cut the construction beams
After the penultimate board, calculate the width that is required for the final board and cut the construction beams so that they are flush. The construction beam is to protrude 10 mm over the edge of the final board so that the edge clip can be positioned as an end fastener.
13. Final board
Position the final board and fix the edge clip in place. Pre-drill a hole for the screw and screw in place applying an average torque.

Assembly of the edge boards

14. Connecting strip
Appropriately pre-drill the connecting strip on the face side facing the edge board (0.5 mm smaller) and screw on using a M8 x 80 mounting screw. Act as shown in Detail 8 with regard to butt joints.
15. Mount the edge board
Mount the edge board parallel to the construction beam using a M8 x 80 fastening screw. Screw together max. 60 mm from the ends and max. 500 mm in connection with each other. The butt joints of the edge boards support
16. Cut the board faces off
Cut the board faces off at a right-angle, leaving a protrusion of 15 mm. Chamfer the cut edges. Maximum board protrusion: 50 mm

Assembly with ConStep system

Our sophisticated ConStep system is the best sub-construction for your torroTIMBER® terrace. The system components impress with their lightness, variable installation heights and ease in terms of laying. Single and double mounts are clicked into the ConStep mounting plate and form the base of the construction beams which will be applied on top.

Easily implemented variable installation heights

Our patented click system allows construction heights of between 98-143 mm (in steps) to be easily implemented.

Preparation of the subsurface

1. Establish a soil formation
Establish a soil formation with a gradient of 4%.
2. Create a ballast bed
Whilst ensuring that it protrudes by 500 mm around the circumference of the terrace, create a ballast bed (including drainage) with a 2% gradient. Apply fine grit to the ballast bed with a gradient of 2%.

Assembly of the ConStep plates

3. ConStep mounting plate
In all of the ConStep mounting plate, click in the single and double mounts to the same height and centrally bond into place with a piece of retaining tape.
4. Distance to the house wall
Position the ConStep panel with double mount at a distance of 80 mm to the house wall and a maximum alignment of 500 mm to the next ConStep panel with double mount.
5. Dimension between axes
Position the ConStep panel with single mount with max. 400 mm dimension between axes in the next row.
6. ConStep double mount
Conclude the end of the deck using a further ConStep double mount. Click the sub-construction into place.
7. Minimise protrusions
Minimise protrusions. In order to do so, turn the ConStep panel where necessary.
8. Reinforce the sub-construction with perforated band
Using the ConStep assembly clip, reinforce the entire sub-construction with perforated band in a crosswise manner.

Assembly of the board with locking clamp

9. Position the edge clamp
Saw into the construction beam from the side from which the boards are to be laid. This must be performed 12 mm from the edge, to a depth of 5 mm and to a width of 2 mm. Position the edge clamp in this groove and, using pliers, fix together with the construction beam and push the board into the edge clamp.
10. Place the locking clamp
Place the locking clamp onto the construction beam, fix into place using pliers and push into the deck board groove. Using the supplied screw, engage the lock lips into every 3rd deck board row on the construction beam.
11. Saw the construction beam to length
After the penultimate board, determine the required width for the last deck board and saw the construction beam to length so that it is flush. In doing so, please note that the construction beam must protrude by 12 mm from the last board (for fixation of the edge clamp).
Assembly of the edge board see items 14 and 15 of assembly on concrete edge stones
Continue at assembly of the sub-construction concrete edge stone point 4 to 9.

Herringbone pattern installation with double sub-construction beam

Min. front-end space of the boards 8 mm and, in the event of floor panel, 5 mm. Use the Distanz Fix component for an ideal gap appearance. At the joint of two boards, use a construction beam at the start and end of the board respectively. Do not hit on a costruction beam.
