Additional Fixings -Stone ● Fix helical ties through the flat face only
● Drill pilot hole in face of SureCav panel
Timber-frame ties
Helical Ties ● Hammer helical tie into timber-frame
Provide additional wall-ties for extra support - various fixing options
Standard frame-ties are fitted each board
course, 450mm vertically and into the
main stud supports of the timber-frame.
Fix additional frame ties, as required, by
drilling and plugging ONLY through the
pod. Always use a SureCav seal washer to
seal the hole in the pod. Ensure the plug is
fixed at lead 50mm into timber-frame and
is long enough to suit the thickness of
insulation.
Helical ties can be inserted where
additional support is needed in any place
through the FLAT surface of the SureCav
sheet only. This is especially useful when
building with rubble stone or flint.
Fitting helical ties
Drill a pilot hole through the flat face
ONLY of the SureCav panel.
Drive the helical tie into the timber-
frame with the fixing tool.
For conventional block-work, where
additional fixings are required when
using rubble stone or flint, first drill and
plug the block before driving in the
helical tie.
