Hilti into brickwork


Recommended Posts

Have used Hilti DX450 attaching battens to concrete befor however we have loads of galvanised joist hangers to attach to a rendered brick wall. We are concerned about fracturing the bricks and also the soft hold of mortar joints.

For the first batch we drilled, plugged and screwed. hard work and slow!

To question: for small holes with the typical spade bit concrete hammer drills you can just hold the drill by hand. You can do this up to 2” which is dine with water cooled mining drill bits if you can find it. You are basically beating the the material with a haa amber to break it then sweeping away the material and repeating. Above that you drill a small hole with a hammer drill and mount a rod to support the drill then use a core hole saw to drill as big a hole as you want. This is the traditional solid concrete approach. The support can be done other ways with a little creativity.

The core drill is cutting with diamonds so fragility isn’t really a problem as long as you go slow enough.

Sorry, I was not very clear. We have to mount floor timbers in a house using galvanised joist hangers as we need to lower the floor. The previous floor rested on top of the wall whereas we need to be 14 inches lower fixing the joist hangers to the rendered brick work lower down. The idea of being able to fire fixings in with a nail gun would save a load of time as the alternative is to drill, plug and screw some 400 times! Tedious.
