Balcony – connection joints

Balcony – connection joints

Balcony – connection joints in the Zürich area – professional, durable and documented.

Eurofugen – Balcony – connection joints in the Zürich area. We prepare the joint plan, verify substrate strength and movement, and select an approved system (neutral‑cure silicone, hybrid/MS polymer, PU) in strict accordance with manufacturer specs. Focus: Naturstein – Entwässerung. Planning priority: Fugenaufbau (Hinterfüllprofil, Primer, 2:1‑Geometrie). Standards: EN 15651 / ISO 11600; weather & UV resistance.

Quality & acceptance

  • Documented execution incl. photo record
  • Uniform, slightly concave finish profile
  • UV/weather‑resistant sealants fit to exposure
  • Ensure bond at two flanks; prevent three‑sided adhesion using PE backer rod
  • Joint width/depth per plan (≈ 2:1)

Planning & preparation

Joint layout based on panel sizes and anticipated movement; critical edge zones are eased. We verify weather and dew point; application only on dry, load‑bearing flanks. Primers are chosen per substrate absorption (e.g., clinker, fair‑faced concrete, fibre cement). Detailing at edges, reveals and penetrations is recorded in drawings. Create square, sound flanks, define depth and install the closed‑cell backer rod precisely. Mock‑ups with cut‑and‑pull checks provide pre‑approval.

Application & control

Maintain movement capability; remove masking in due time and verify edge adhesion. Use UV‑stable systems and protect adjacent surfaces from contamination. Random cut‑and‑pull checks, width/depth measurements and visual inspection are recorded. Transitions at profile joints and material changes are re‑worked separately. Apply sealant without bubbles, fill the joint evenly and tool to a slightly concave profile.

Interfaces to adjacent trades are clarified to avoid follow‑on damage.

Care guidance and maintenance intervals are included at handover.

Planning & preparation

Clean substrates, define edges and limit bond areas; primers & backer rod are matched to substrate and width. Mock‑ups and dew‑point checks secure approval. Interfaces are coordinated before start.

Application & control

Apply sealant bubble‑free, tool evenly and control dimensions. Check edge adhesion, remove masking in time and re‑work transitions neatly. Everything is recorded.
