LSE Structural Solutions use the
Helifix
system for repairing
masonry.
Wall 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.
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.

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.
