Cracked internal walls which have separated from the main outer walls can be repaired and reconnected both internally and externally.

Predetermined slots on the internal wall are channelled out to the specified length right into the corner. Angled holes of 10mm are drilled from the corner into the external wall. Single lengths of Helifix HeliBar are bent to shape with the angled end being Helifix PolyPlus resin bonded into the hole and the remainder Helifix HeliBond grouted into the internal wall.
