Drilling into concrete floor
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? |

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. NT |

Or what is the solution to my problem? 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.
