Exterior Beam and Block - OK to use pre-concreting

Recommended Posts

I'm building a driveway that is on a steel platform with beam and block on top of that. Is it OK to screed this and use it for storage (no vehicle traffic)  before putting the concrete / mesh top on it for a few months? Or should I wait another couple of weeks and get the concrete on first? Just not sure how stable this is with a screed on.

You can load out a beam and block floor that has where you just brush in a lean mix grout.  The concrete would give added strength but you should be OK.  The supplier should advise on max loadings.  I have seen one fail but they had staked blocks 2 packs high x 2 along one beam and the floor had not been grouted.
