Drilling concrete panel.

[Grassman]

I have to put a 100mn hole through a 100mm thick concrete panel. Is it difficult?
Just wondering what happens when I hit the reinforcing!

diamond core will eat the reinforcing

Go to your local tool hire centre.we often use em on building jobs to put vent holes through walls,in a tidy fashion

I'll have some offcuts tomorrow you can practice on. Better still come and cut my panels, familiarise yourself

Get a strong magnet and find the rod first

Look at the ends. You will see clearly where the wires are

Doddle with the right kit.
Pain without the right kit
Local dairy engineers did the last one for us

Is it possible you can bore between two rods, save weakening the panel.
As Bob says, find rods on end. Some 4" panels miss out a rod or two, you might be lucky

I don't think I can see the ends as they are in girders.

Ah problem then !
If you know which firm made them then there might be a specification on the website

Good idea. I have some strong magnets and a small metal detector.

Good diamond core drill, but don't try and push it through the reinforcing, it takes the teeth off and might yours if the slip clutch doesn't work quick enough.
When you get to the bars just cut them out with the oxy/acetylene and then carry on drilling.

Give the manufacturers a ring, they should be able to give you the position of the reinforcing.

This is a 100mm thick panel. 1.2 in height. Sorry didnt have a measure handy!!!

Diamond core and get plenty of them. We put 18 holes through 150mm thick panels for air tunnels (grain shed) and went through 9 diamond cores. We were 250mm diameter. Took a whole day 3 of us taking turns as it’s a rough job.

That gives me hope! Only need one near the bottom.

Luckily it's nothing like as bad as that!

Yep it was an afterthought so the panels were already in place so we couldn’t see the wires although the tunnels had to be evenly spaced so it wouldn’t of mattered anyway. I can honestly say it’s one of the worst jobs I’ve ever had to do.

 

[Grassman]

Just tried with magnets but no joy.
Then tried with the metal detector/ stud finder and it shows them spaced as in the picture so looks hopeful
