Helifix Structural Repairs

The cottage was condemned by
the structural engineer after the
gable wall collapsed.

Strutt & Parker instructed LSE Structural Solutions to propose a scheme to repair stabilise and strengthen the property.
HELIFIX cemties were installed into the ends of the walls to a depth of about 500mm with 500mm exposed. The ties bound the stone work and were used as starters to bond the new block work

HELIFIX crack stitching and Bowties
were installed to repair the other defects.

The finished work was guaranteed by
HELIFIX for a period of 10 years.

Crack Crackstitching

Crack Stitching is used when a building starts to get vertical cracking, once the cause of the crack has been determined as suitable crack stitching method can be employed. Crack stitches are installed into the bed joints across the cracks. The bed joints are cut out and then the helical bar is grouted in place preventing any future movement. Helibeaming

Heli-Beaming is used to create a structural beam, by installing long lengths of helibar at a set spacing and using the existing masonry to create a beam. This method is used where subsidence is a problem and can be used in conjunction with under pinning. Remedial WalltiesWall Tie Replacement is carried out when the existing ties become corroded and can no longer carry out their function, which is to hold two skins of masonry together. This is a non-destructive repair which involves isolating the existing ties preventing them from causing any further damage. Then new helical ties are installed by drilling a pilot hole then using special equipment screwing them in to hold the two skins of masonry together again. The dry fix ties used for wall tie replacement can also be used to pin arches CemtiesCem-Ties are used to prevent walls that are separating from separating any further. A holes are drilled through the damaged area in a set pattern then cem-ties are installed using special equipment the ties is a length of Helical bar and it grouted in place. BowtiesBow-Ties are used to stop walls that have become unstable from falling down by tieing then into the floor joist, and using the floor as a diaphragm. They are install by drilling through the masonry at joist level then screwing them into the joists. They are then anchored to the masonry using a resin compound. Timber Resin RepairsTimber Resin Splices are used when a timber joist or beam end has become decayed and can no longer carry the load required. They are simple to install by our experienced technicians and are less destructive than the alternative which is a full replacement. The decayed timber is propped then the decayed end is then removed, slots are then formed and the timber splice is then positioned. The area is then sealed and resin is either poured or injected into the slots. Bower BeamBower Beams are used to replace joist ends that have decayed; they are a simple way to repair the joist without the need for a full replacement which can be very destructive. The joist is supported the decayed end is then removed and the bower beam is them bolted onto the joist end.
