SinusSLIDE® sinus expansion joints tested by Toyota

To check the difference, sinusoidal and straight expansion joints were installed in one of the TOYOTA building, on one pass. Forklifts have driven one wheel through sinusoidal expansion joints and the other through simple expansion joints.

After 4 years, the first crushing of the concrete was visible at the straight edge of the expansion joint. This was obviously just the beginning of an irreversible process that is now beginning to accelerate. The destruction of the entire straight expansion joint was only a matter of time.

SINUS expansion joints have remained intact.
