A finalist in BBC2's 'Restoration' series, Grade I Listed Llanelly House, is Llanelli's most notable historic domestic buildings. Built in 1714, it is a large Georgian town house with an impressive frontage and was purchased by Llanelli Town Council in 1998 with the aim of completely restoring the property and reopening it in 2013 as a Genealogy Heritage Centre. To allow the renovations to take place without fear of weakening the building fabric, the masonry was stabilised and reinforced using Helifix structural repair techniques.
Helifix Approved Installer, TRAC Structural, was asked to address the repair of a large timber beam running above the shop front window and door on the front elevation. The timber beam, which provided support for two storeys of 650mm thick rubble-filled wall above, was in a very poor condition having suffered from wet rot and decay caused by long term water ingress from a fractured rain water pipe.
The beam repair required the removal of large sections of decaying timber that were providing support for the wall. To secure the wall and provide support, pairs of stainless steel HeliBars were bonded into the masonry at two levels above the timber beam, both internally and externally, to form a deep masonry beam using the existing brickwork. Within the area of the HeliBeam the rubble-filled wall was consolidated by cross pinning with fully grouted CemTies in a lattice arrangement.
The Helifix 'permanent temporary works' reinforced and stabilised the masonry, working in conjunction with traditional temporary support props to carry the load of the two storey structure and enabling the safe removal of decayed timber and the reconstruction of the beam.
