Expansion Joint Applications

Renewal of floor expansion joints with flexible sealant systems and Sika FloorJoint prefabricated composite panels, in keeping with the traffic and the use.

Why expansion joints

The joint is where the structure breathes.

Structures and floor slabs move: they expand with temperature and deform under load. Expansion joints are left to accommodate this movement; yet the joint is the floor’s hardest-working and most neglected detail. An expansion joint that has lost its function becomes a crossing with broken edges, an obstacle that wears out equipment and jolts the forklifts.

In expansion joint renewal we work with two solution families: flexible sealant systems for joints still in movement, and Sika FloorJoint for lines carrying heavy, constant traffic. Made of prefabricated carbon-fiber-reinforced composite panels, FloorJoint turns the joint into a crossing flush with the floor, free of vibration and of any perceptible profile. Edge repair is treated with the same care as the joint itself in both families, for the sake of the system’s life.

What sets this system apart
  • Designed for the movement: The detail is selected for the expected amount of movement and the traffic.
  • Two solution families: Flexible sealant systems or Sika FloorJoint prefabricated panels.
  • Edge repair included: Broken joint edges are rebuilt in a form suited to the system.
  • Traffic resistance: A flush, vibration-free surface under forklift and vehicle traffic.
Where it is used

Where movement crosses paths with traffic.

The expansion joint detail is selected for the traffic the joint line carries and the conditions of use.

Application discipline

The four conditions for touching the structure.

Every intervention on the structural system follows the same discipline: diagnosis, design, supervised application and complete records.

01

Diagnosis and design

The existing condition is documented; the intervention is limited to the scope and detail defined by the strengthening design.

02

Surface and member preparation

The application surface is brought to the condition the design requires; the preparation defines the system’s life.

03

Supervised application

The application is carried out under civil engineering supervision, adhering to the manufacturer’s system approvals.

04

Records and handover

Every stage is documented; the work is handed over with a traceable application file.

System cross-section

The detail accommodates the movement; the edge carries the detail.

A joint system’s life depends on the soundness of the edges as much as the flexibility of the filler; the two sides work together.

  • Backer rod or epoxy bedThe underlying preparation that makes the system work at the right cross-section with full adhesion.
  • Repaired joint edgesThe edges carrying the system, rebuilt where required.
  • Existing floor slabsThe moving concrete slabs the joint separates.
