Helifix DryFix Power Driver Attachment

Drill Attachment for Installing DryFix Ties. The DryFix Power Driver Attachment (PDA), fitted to an SDS hammer drill, ensures the quick, easy, and non-disruptive installation of DryFix ties and fixings. 

DryFix can be installed through the brick or the mortar. If the mortar is of good enough quality, this will avoid any damage to the brick, but it must be tested at various locations as mortar strength can vary throughout a structure. If unsure of the mortar quality then install DryFix through the brick as it leaves only a small entry hole, which can be concealed with drilled-out brick dust. By installing through the brick a reliable connection can be guaranteed. Ties should be installed about 3cm from the end of the brick to avoid the frog. 

Drilling Notes: 

Correct drilling techniques are essential to ensure efficacy of remedial wall ties, and to minimise aesthetic and structural damage to the property under repair. Helifix requires the use of Rotary Percussion drill bits for drilling pilot / clearance holes wherever possible. This keeps spalling of the rear side of the outer leaf masonry, in cavity situations, to a minimum. Any spalling of the brick / block rear will reduce the effectiveness of the wall ties installed.

Rotary hammer drills, SDS type, are always used to drive the Helifix tie into position with the DryFix Power Driver Attachment for masonry stabilisation.
