LEAK REPAIR

SHOTCRETE DEFECTS & REPAIR

This leaking hole, which resulted from a bubble in an over-thickened shotcrete layer, was hanging from the ceiling's curves.

Plugs made from KF-C were used for curtailing the flow of water prior to the final KF-F application.

This hole was welded with KF-F spray, which turned it into a solid and glassy looking patch.

These horizontal leaking strips were caused by the shotcrete layer sliding from the ceiling's curves.

The leaking strips were repaired with KF-F welding technology.

This vertical leaking strip was caused by a misplaced isolation membrane.

The leaking strip of misplaced membrane was welded with a premix of KF-C + KF-F in a ratio of 1:3.
