Crack stitching

Lengths of helical HeliBar extending 500mm either side of the crack are bonded into cut slots, normally the mortar beds, with HeliBond grout for a reliable and permanent solution. Where cracks are less than 500mm from an external corner or an opening, at least 100mm should be bent round the corner and bonded into the return wall or bent and fixed into the reveal, avoiding any DPC membrane.

Reconnecting party walls with external walls

Predetermined slots on the internal wall are channelled out to the specified length right into the corner. Angled holes of 10mm are drilled from the corner into the external wall. Single lengths of HeliBar are bent to shape with the angled end being PolyPlus resin bonded into the hole and the remainder HeliBond grouted into the internal wall.

Helibeam Lintel Repair.

Repairing or creating flat arch lintels where lintels have lost their load-bearing capabilities the traditional solution is to cut out the brickwork, mechanically support the masonry above and install a new lintel, which is disruptive, time consuming, expensive and aesthetically undesirable.

The Helifix method involves parallel lengths of HeliBar, which are bonded into the specified cut slots above the opening or lintel to form masonry beams and create lintels using the existing brickwork.

Repair of bay windows

Twin HeliBars are bonded into predetermined cut slots around the bay above and below the window with the ends embedded in the front elevation. BowTies are driven into the joist ends via clearance holes in the masonry and low level cracks are stitched with single HeliBars.

Creating masonry beams

Where masonry has cracked and failed as a result of ground movement, component failure, weathering or increased loads and stresses, the innovative and versatile Helibeam System ties the masonry together and creates deep masonry beams within the existing masonry.

The Helibeam System uses long parallel lengths of HeliBar reinforcing bars bonded into predetermined cut slots (normally the mortar beds) with HeliBond grout to form deep masonry beams which distribute the building loads. These can be used to resist vertical loads to prevent building subsidence or the horizontal displacement of a bowing wall next to internal stairwell where BowTies cannot be used as there are no joists at this point.

Stabilising bowed walls into joist sides

BowTie HDs are inserted through clearance holes in the masonry and are power-driven through the first and second joist (and third, if required)before the outer end is bonded into the masonry with PolyPlus resin.

Replacing cavity wall ties:
DryFix wall ties are power driven directly into both leaves, via a small pilot hole of around 6mm diameter.
RetroTies are driven into a 4.5mm pilot hole in the far leaf, via a clearance hole in the near leaf into which they are bonded with PolyPlus resin.
ResiTies are resin bonded into a 10mm hole in both leaves.
