Main advantages of our expansion joints

  • up to 50 mm for horizontal displacements
  • from -10mm to +10 mm for vertical displacements
  • from -20mm to +20 mm for transversal or rotational displacements

  • Simple and robust design – Two aluminum alloy profiles connected by an elastomer profile
  • Aluminum profile for corrosion protection
  • Prestressed anchorages
  • No deep groove

  • Two barriers against water leakage, including one not exposed to traffic
  • Continuity of the waterproofing system

Adapted to concrete and steel structures

No free-moving metal parts

Cimac joints consist of the following components:

  • an aluminum extruded profile
  • pre-stressed anchors
  • a continuous elastomeric profile connecting the metal elements and a dedicated membrane underneath to ensure the continuity of the waterproofing system
  • standard accessories such as intersection joints or T-joints.

Installation

For new structures, the joints can be anchored in a recess or on supporting elements by fixings pre-placed during the construction of the support.
For existing structures where such provisions have not been made, drilled, controlled tightening fixings can be used.

Our other type of expansion joints

Road expansion joints

Expansion joints for road bridges ensure the continuity of the road surface and its load bearing capacity while guaranteeing the freedom of movement of the structure. As a specialist in structures and bridges, we give top priority to the robustness of our joints.

Railway expansion joints

Freyssinet railway joints are specifically designed to prevent ballast or other components from seeping into the joint gap at either end of the deck, regardless of displacement. Our four main products, developed in close coordination with rail operators and backed by 40 years of experience, cover movements up to 900 mm.
