Concrete – movement joints

Concrete – movement joints

Concrete – movement joints in the Zürich area – precise execution, on‑schedule handover.

Eurofugen – Concrete – movement 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: Risse – Reaktionsharz. Planning priority: Fugenaufbau (Hinterfüllprofil, Primer, 2:1‑Geometrie). Standards: EN 15651 / ISO 11600; resistances per product data sheet.

Quality & acceptance

  • UV/weather‑resistant sealants fit to exposure
  • Crisp edges without staining
  • Uniform, slightly concave finish profile
  • Ensure bond at two flanks; prevent three‑sided adhesion using PE backer rod
  • Joint width/depth per plan (≈ 2:1)

Planning & preparation

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

Application & control

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

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.
