Helifixing Structural Cracks on Edinburgh Tenement
/ The Challenge
A four-storey sandstone tenement on Warrender Park Road had a stepped crack running 8 metres through the gable wall. The crack widened after winter freeze-thaw cycles, and water was penetrating two top-floor flats. Scaffold was refused by Edinburgh City Council due to pavement width restrictions and tram line proximity.
/ The Solution
We deployed two IRATA Level 3 technicians by rope access from the roofline. Using HeliFix stainless steel bars and helical polymer grout, we stitched the crack across 14 bed joints. All work was completed without scaffold, without street closure, and without disturbing residents.
/ The Result
Crack permanently stabilised. Structural engineer sign-off achieved within 48 hours. Total cost to the property factor was 45% less than the scaffold-based quote. Residents reported zero disruption.
