Drilling into concrete

[Sparky]

Hi All

I wonder if anyone could recommend the length of time to leave before drilling into new concrete (as in a few days old)to fix a rawl bolt into place

depends on the size and thickness of concrete you have layed
how thick is the concrete ?

[Sparky]

Iam no expert but if its been down a few days for that size it should b ok.
i have just layed concrete for a garage base its 100 mm thick i have been told to leave it a week before drilling into it.

Thanks

My base is also 4" thick and not 40mm I typed it in a bit of a rush !

So guess I will give it a week and have a go

the longer you leave it the harder it is to drill into it.

sds drill on hammer with sds drill bit goes through concrete no probs

not to hijack this thread but how long to drill into a 300mm base, same type of thing, rawl bolt fixtures?

As said before, decent SDS hammer drill so no worries!

i,v drilled next day, and used epoxy as added security, and the posts are still there years later:)

Yep - I shuttered a section within a milton ring, poured the concrete to form the 'bench' for the hydroflow control device - removed the shutter the next morning and drilled the 14mm holes for the rag-bolts - the concrete was hard as hell - drilled as white dust.

Aslong as you have a decent mix, you'll be fine.
