Helifix helps preserve historic Titanic dock pump house

Helifix non-disruptive and concealed masonry repair systems have been installed on the large pump house adjacent to the historic 850 feet long Thompson Graving Dock in Belfast, where Titanic and its sister ship Olympia were both fitted out.


Opened in 1911, this long terrace of gabled brick buildings required major structural repairs and stabilisation due to historic settlement and rotation. Now part of the Titanic Foundation, it was important that these repairs were sympathetic, restoring structural integrity while retaining the original appearance of the buildings.

Over 500 metres of stainless steel HeliBars were bonded into channelled-out mortar beds to stitch cracks in the masonry, which after re-pointing, were completely hidden from view.

Bespoke manufactured SockFix grouted sock anchors, ranging from 1.2 to 5 metres in length were used to reinstate failed arches and lintels, and reconnect main elevations to internal cross walls. These anchors were inserted into core-drilled clearance holes before being pumped full of grout, expanding the sock to fill voids and forming a strong mechanical connection with the masonry; the retained cores were then replaced in the external masonry to create an almost invisible repair.

Furthermore, providing additional peace of mind, this major repair programme was undertaken by a Helifix-trained Approved Installer and covered by a Helifix 10 year insurance-backed warranty.
