I want to drill a number of holes through the concrete floor of my house. This is to fix some heavy equipment to the floor. I presume there is a damp proof membrane which would be punctured.

Is this advisable to do? Would injecting some sort of silicone into the holes make good the damp proofing? Or what is the solution to my problem?

expansion bolts & bitumen, silicone, or any other totally waterproof
gloop. Note that many things sold as waterproof aren't really.

Another option is to resin some stud in (threaded rod). The resin does
both jobs then.

The DPM is likely around 100mm down so you may well not come near it
Put some silicon down if you're worried

use resin fixed anchors and that will avoid the problem ... especially
if you don't thru drill ... floor should be at least 150mm thick ... so
a resin in anchor at 100mm deep would be the way to go.
They put far less stress on floor ... and give a better fixing

If it's heavy equipment does it really need bolting down?
Our heavy duty gym equipment is fabricated with drilled lugs however we
don't suggest nor advise bolting the kit to the floor as it wouldn't go
anywhere. Only one place that insisted on bolting it down was a big
military and more the fact the lugs were there in the first place and
HSE (or whatever they have there) insisted on bolting everything down.

Just a thought...
