Planning principles

  1. Avoid contact between the construction elements and the ground.
  2. Ensure that the subsoil is firm and has a good bearing capacity.
  3. For applications that require an official technical approval, a static sufficiently measured, bearing and walkable foundation as a support for torroTIMBER® deckboards / sub-constructions is also required.
  4. Only use torroTIMBER® construction beams.
  5. In principle, all holes must 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.
  6. Do not lash down or brace the terrace during construction.
  7. The deckboard must maintain a distance of 2 mm to all fixed components.
  8. Ensure a sufficient amount of ventilation from underneath by observing the joints.
  9. Do not fill cavity spaces between the level surface of the gravel and sub-construction elements.
  10. The minimum gradient is 2%. The maximum deckboard protrusion over the last sub-construction is 50 mm.
  11. Production-related dimension tolerances regarding length, width and thickness are to be taken into account during assembly.
  12. All dimensions must be examined on site.
  13. Only use original torroTIMBER® parts and observe the rules contained in this construction manual. Otherwise no warranty can be provided.
