Hi group
I am building cement & brick foundations for decking.
How long after building the foundations must I wait, before drilling and inserting load bearing bolts, to attach the decking.
i.e. - is it strong enough as soon as it is dry, or does it get stronger with age?
thanks, Ian
At least 48 hours in these temperatures. A week might be better.
I think full strength is reached in 30 days. It's an exponential process so half strength is reached considerably sooner than 15 days, I think it's more like 4 days.
Andy.
