Crack Repair, Private Court in Monte Negro

A private sport court in Reževići experienced persistent structural cracking caused by construction-related subsidence and foundational instability. The cracks were visible not only on the asphalt surface but also on adjacent concrete retaining walls, highlighting the severity of the issue.

Over the years, multiple repair methods were trialed—without lasting success. These included:

• Court Patch Binder – Provided only temporary repair before cracks reappeared.

• Two-component PU adhesive – While flexible, it led to surface issues due to seasonal temperature fluctuations: the adhesive would depress in cold weather and rise above the surface in heat, causing visible distortion and performance concerns.

OUTCOME

The performance of this epoxy-based approach is being monitored over time, but early results are promising compared to previous methods.

Additional Experiment: Crack Tape Isolation

A second technique was tested on a separate client’s court where old asphalt had been patched with new material—another known weak point where cracking occurs.

1. Tape Isolation Method:
   The junction between new and old asphalt was covered with tape bonded only along the crack using two-component PU adhesive. A 2 cm margin on either side was left unglued so the tape could “float,” minimizing stress transmission to the acrylic surface above.

2. Finish:
   Several coats of AR were applied over the tape, followed by full-court resurfacing.
