If existing pad is really good it can be done. But to make it the best epoxy rebar every 16" (should be drilled in every place), only need to drill in 4"-6" or so. With epoxy in, it will tear the concrete apart before that rebar will ever pull out. Do it all the time on bigger slabs with multiple pours instead of sticking rebar out.

But OP pad is 30 years old, way to old to be adding onto. Infact almost guaranteed if you tried to drill in you would see how soft the concrete has gotten. Plus that concrete is probably like 20 MPA if your REALLY lucky.

THIS IS THE DUMBEST post i have ever read. concrete continues to gain strength for up to 75 years. if your lucky you would be able to drill into it.soft.......OOK.
that concrete is stronger than it was 28 days after it was poured 30 years ago.

He is probably talking about a some crumbled side walked pour with a cement mixer many moons ago (how much cement with this dirty gravel). Sounds like maxwell has had some practice drilling in 30 year old concrete Ha ha ...How many holes and hour did you manage?

Ya there's a few threads with some bad info flying around here. One more reason I hate all these handyman tv shows. Everyone is a expert. In case anyone's wondering it's called hydration.
I can't wait for the season premier of boilermaking with Sven.

Lucky? Ya lucky if it doesn't crumble. Never ever had any issue drilling into any old concrete up to 60 years old, besides for it crumbling or cracking. Drills like butter or easier. 5 years old or so will be harder, but 30 years? Nope. Maybe in a perfectly controlled environment, but exposed to elements breaks down the concrete over time. Yes part of the reason is older concrete is not as good as todays, but a large part is also it getting weaker over a long period of time.

It's easy to sit behind a desk and say it's suppose to get harder, but go try for yourself. You'll find out the truth........
